Brady Bass, the plaintiff in this suit, appeals a summary judgment dismissing his claims against Convenient Care, L.L.C. d/b/a Total Occupational Medicine (TOM), a drug testing collection facility. After review, we affirm.
FACTUAL AND PROCEDURAL BACKGROUND
Mr. Bass was employed by Coastal Corrosion Control, Inc. (Coastal) as an onshore laborer. In January 2017, Coastal directed Mr. Bass to present to TOM for employment-related urine and hair sample drug testing. Mr. Basss urine test was negative, but his hair sample test returned a positive result for marijuana use. According to Mr. Bass, the positive result for marijuana was a false positive, which ultimately negatively impacted his ability to maintain employment in the petrochemical industry.
Mr. Bass filed this suit against TOM; DISA Global Solutions, Inc. (DISA), Coastals third-party drug test administrator; and Psychemedics Corporation (Psychemedics), the laboratory that performed the positive hair sample test. He alleged the defendants negligently mishandled his hair sample and conducted the drug test in an unsanitary and contaminated environment, resulting in the false positive drug test result for marijuana.
1
Mr. Bass alleged TOM collected the hair sample under the direction of DISA-trained-and-managed employees at TOMs clinic and then sent the hair sample to Psychemedics for chemical analysis. Mr. Bass also alleged the defendants defamed him by reporting and publicizing the alleged false positive drug test result to national drug testing databases, which prevented him from finding employment and caused him humiliation and embarrassment. Mr. Bass sought damages resulting from the false positive drug test, including lost employment, lost wages, lost benefits, loss of enjoyment of life, defamation, and emotional pain and suffering.
Specifically as to TOM, Mr. Bass alleged: the TOM employee who collected his hair sample (later identified as Matthew Guarisco) did so in an unsterile, disorganized, and unsanitary area while using unsterile collection equipment, which likely led to his hair sample being mislabeled or otherwise contaminated; Mr. Guarisco violated Substance Abuse and Mental Health Services Administration
2
(SAMHSA) regulations by failing to have Mr. Bass initial the specimen container housing his hair sample; and TOM committed negligence per se by violating statutory duties contained in the Louisiana Drug Testing Statute (La. R.S. 49:1001, et seq.), SAMHSA regulations, and PH MSA regulations.
3
The three defendants separately filed motions for summary judgment seeking dismissal of Mr. Basss claims. This Court affirmed a summary judgment dismissing Mr. Basss claims against Psychemedics, finding Mr. Bass failed to present evidence of Psychemedicss negligence, was not entitled to assert a negligence per se claim under certain statutes and regulations, and failed to present evidence of Psychemedicss unprivileged publication to a third party to support his defamation claim. Bass v. DISA Global Solutions, Inc., 2020-0071 (La. App. 1 Cir. 12/30/20), 318 So.3d 909, writ denied, 2021-00147 (La. 3/23/21), 313 So.3d 273 (Bass I). This Court reversed a summary judgment dismissing Mr. Basss claims against TOM and remanded for further proceedings, finding an experts affidavit created disputed factual issues regarding the validity and integrity of TOMs collection process. Bass v. DISA Global Solutions, Inc., 2019-1145 (La. App. 1 Cir. 6/12/20), 305 So.3d 903, 910, writ denied, 2020-01025 (La. 11/4/20), 303 So.3d 651 (Bass II). And, this Court vacated a judgment denying DISAs motion for summary judgment and remanded due to the trial courts failure to rule on evidentiary objections before ruling on the motion. Bass v. DISA Global Solutions, Inc., 2022-0957 (La. App. 1 Cir. 9/26/2022), 2022 WL 4463074.
In this appeal, we review a February 15, 2023 judgment granting TOMs second-filed motion for summary judgment and dismissing Mr. Basss claims against TOM. In a related appeal, our Docket Number 2023 CA 1307, we review a February 24, 2023 judgment granting DISAs re-set motion for summary judgment and dismissing Mr. Basss claims against DISA. On DISAs motion, this Court consolidated this appeal with Docket Number 2023 CA 1307 for oral argument and submission only.
In a single assignment of error, Mr. Bass contends the trial court erred in granting TOMs motion for summary judgment and dismissing his claims against TOM. Mr. Bass argues the trial court ignored evidence of Mr. Guariscos negligence, of possible sample contamination, Mr. Basss later-administered negative drug test,
4
and an “accumulation of evidence” creating genuine issues of material fact. We note that Mr. Bass does not assign error to nor discuss the trial courts dismissal of his claims against TOM for invasion of privacy, defamation, and negligence per se, and as such, we consider these issues abandoned. See Uniform Rules - Courts of Appeal, Rule 2-12.4(B)(4).

DISCUSSION
Summary Judgment
An appellate court reviews the grant or denial of summary judgment de novo under the same criteria governing the trial courts consideration of whether summary judgment is appropriate. Bass I, 318 So.3d at 916; Bass II, 305 So.3d at 906. A court shall grant a motion for summary judgment if the motion, memorandum, and admissible supporting documents show there is no genuine issue of material fact and that the mover is entitled to judgment as a matter of law. See La. C.C.P. art. 966(A)(3) and (4).
6
The summary judgment movant maintains the burden of proof. La. C.C.P. art. 966(D)(1). Nevertheless, if the movant will not bear the burden of proof at trial on the issue before the court on the motion, his burden is satisfied by pointing out an absence of factual support for one or more elements essential to the adverse partys claim, action, or defense. Id. Thereafter, the adverse party must produce factual support sufficient to establish he will be able to satisfy his evidentiary burden of proof at trial. Id. If the adverse party fails to meet this burden, there is no genuine issue of material fact, and, if appropriate, the court shall render summary judgment against him. La. C.C.P. arts. 966(D)(1) and 967(B).
Negligence
Because it is the substantive law that determines materiality in a summary judgment setting, whether a particular fact in dispute is material can be seen only in light of the substantive law applicable to the case. Bass I, 318 So.3d at 917. Mr. Basss claims against TOM are based on negligence and are subject to a duty/risk analysis. See Id. To prevail at trial, Mr. Bass would have the burden of proving: (1) TOM had a duty to conform its conduct to a specific standard (the duty element); (2) TOMs conduct failed to conform to the appropriate standard (the breach element); (3) TOMs substandard conduct was a cause in fact of Mr. Basss injuries (the cause in fact element); (4) TOMs substandard conduct was a legal cause of Mr. Basss injuries (the scope of duty element); and, (5) proof of actual damages (the damages element). Id.
Generally, under Louisiana law, a person has a duty to conform his conduct to the standard of care of an average reasonable man in like circumstances. Bass I, 318 So.3d at 917; Bass II, 305 So.3d at 907. Thus, for TOM to have breached a duty, it first must have owed a duty, and secondly, it must have acted unreasonably in collecting the hair sample from Mr. Bass. Bass II, 305 So.3d at 907. As conceded by TOM on appeal, a collector of a hair sample for drug testing purposes has a duty to maintain the integrity of the sample. See Williams v. Gulf Coast Occupational Medicine, Inc., 2015-1130 (La. App. 1 Cir. 2/26/16), 2016 WL 770376, *5, n.5, writ denied, 2016-0577 (La. 5/13/16), 191 So.3d 1056. Notwithstanding the collectors duty, a plaintiff alleging a collectors negligence still must show that the breach of that duty was the cause in fact of his injuries. See Williams v. Guif Coast Occupational Medicine, 2022-1224 (La. App. 1 Cir. 2/10/23), 2023 WL 1945454. The question of whether a collectors negligence was the cause of a false positive drug test may be decided on a motion for summary judgment. Id.
TOM contends that the trial court correctly granted its motion for summary judgment, because Mr. Bass will be unable to prove the breach and cause in fact elements of his negligence claim. In opposition, Mr. Bass argues the summary judgment evidence establishes genuine issues of material fact as to whether Mr. Guarisco negligently collected his hair sample, “which resulted in environmental contamination” of the sample. After de novo review, we conclude TOM is entitled to summary judgment, because Mr. Bass has failed to produce factual support sufficient to establish that he will be able to meet the cause in fact element of his burden of proof at trial.
Cause in Fact
To establish cause in fact, a plaintiff must prove a cause and effect relationship between a defendants conduct and the plaintiffs loss. The cause in fact test requires that “but for” the defendants conduct, the plaintiff would not have sustained the injuries. Pellerin v. Foster Farms, L.L.C., 54,829 (La. App. 2 Cir. 1/11/23), 354 So.3d 790, 796. Although the cause in fact inquiry is a factual determination best made by the factfinder, summary judgment may be appropriate when there is no evidence to show that the cause in fact test has been met. Young v. Department of Transportation and Development, 2020-0526 (La. App. 1 Cir. 12/30/20), 318 So.3d 887, 892.
In support of its motion for summary judgment, among other evidence, TOM filed the affidavit and report of Dr. Carl Selavka, a forensic scientist with experience in lab-based hair and urine drug testing. In preparing his report, Dr. Selavka reviewed lab results with supporting chain of custody files and analytical data showing three positive tests for marijuana on the hair sample Mr. Guarisco collected from Mr. Bass on January 16, 2017, Mr. Basss original and amended petitions, and Mr. Basss deposition testimony. In his report, Dr. Selavka noted Psychemedicss first positive test result. He then explained that, in such a case of an unexpected positive test, due to specific factors related to hair morphology and drug incorporation, and their impact on hair drug testing interpretation, some laboratories include aggressive wash procedures in their re-test protocol to insure that no common environmental causes could lead to another positive result. He noted that Psychemedics and Omega, a second laboratory, performed this type of aggressive wash procedure of Mr. Basss hair sample before re-testing it, and the hair sample twice again tested positive for marijuana. Dr. Selavka then opined,
[E]ven if hair collections by “ungloved Collectors” involve “dirty scissors” and “dirty tables” ․[,] Psychemedics and Omega employ extensive, aggressive wash steps prior to [follow-up] tests which [remove] any environmental drugs from the sample. No external contamination contributed to the [hair drug test] Positive Marijuana result reported for Mr. Bass. (Emphasis in original.)
This summary judgment evidence points to an absence of support for the cause in fact element of Mr. Basss claim. That is, with Dr. Selavkas report, TOM has shown that, even if Mr. Guarisco breached his duty to maintain the integrity of Mr. Basss hair sample (by negligently collecting the hair sample), such is not proof that breach of that duty was the cause in fact of the positive hair sample test. At this point, the burden shifted to Mr. Bass to produce factual support sufficient to establish that he could prove cause in fact at trial. See La. C.C.P. arts. 966(D)(1) and 967(B).
In opposition to TOMs motion, Mr. Bass points to summary judgment evidence that focuses on the integrity of TOMs collection process and the reliability of hair sample drug testing, not on causation. Specifically, Mr. Bass references depositions and affidavits of Andrew Easier, Mr. Basss expert in drug testing collection procedure, and of Daniel Buffington, Mr. Basss pharmacology and toxicology expert.
7
In his deposition, Mr. Easier opined that Mr. Guariscos collection process was flawed, primarily because he failed to sanitize the collection table in Mr. Basss presence before collecting Mr. Basss hair sample. However, Mr. Easier specifically testified that he was giving no opinion as to whether Mr. Basss hair sample was somehow contaminated because it touched the table; he stated that this causation inquiry was better addressed by a pathologist, and he would leave the “science of drug testing” to scientists. Similarly, in his deposition, Mr. Buffington stated that he was not taking a position as to how Mr. Basss hair was contaminated and admitted that he had no facts to support a finding that Mr. Basss hair sample was contaminated at TOMs facility or at either testing laboratory.
8
Rather, the focus of Mr. Buffingtons opinion was that, in general, hair drug testing is unreliable and of limited clinical utility. Specifically as to Mr. Bass, Mr. Buffington opined that the reliability of Mr. Basss thrice-positive hair test was questionable given that another hair sample tested negative only eleven days after Mr. Guarisco took the first sample. However, the reliability of hair sample drug testing is not at issue in this appeal, as Mr. Bass has made no such claim in this case. Thus, Mr. Buffingtons opinion regarding hair sample drug testing does not present a material issue for this Courts review. See Seal v. Louisiana Farm Bureau Mutual Insurance Company, 2021-0988 (La. App. 1 Cir. 3/16/22), 341 So.3d 659, 662 (For summary judgment purposes, a fact is material if it potentially ensures or precludes recovery, affects a litigants ultimate success, or determines the outcome of the legal dispute.)
Mr. Basss summary judgment evidence primarily focuses on Mr. Guarsicos alleged negligence in collecting his hair sample, i.e., that Mr. Guarisco collected the sample in an unsterile, disorganized, and unsanitary area while using unsterile collection equipment, “which likely led” to his hair sample being contaminated. But, Mr. Bass has provided this Court with no evidence to show that any of Mr. Guariscos conduct, even if true, “likely led” to contamination of Mr. Basss hair sample, somehow turning a negative hair sample test result into a false positive result for marijuana. Proof of negligence is not a substitute for evidence of causation. See Jenkins v. Big City Remodeling, 515 S.W.3d 843, 852 (Tenn. 2017). See Williams, 2023 WL 1945454 at *1 (granting summary judgment on appeal based on plaintiffs failure to produce sufficient evidence to demonstrate that he would be able to meet his burden of proving the defendants negligence caused his damages); also see Henry v. Ahern, 2021-0438 (La. App. 4 Cir. 2/9/22), 335 So.3d 871, 882 (affirming summary judgment because plaintiff failed to establish a causal connection between the defendants actions and the plaintiffs alleged loss) and Smeltzer v. Medtox Laboratories, 24 I.E.R. Cas. (BNA) 1555, 2006 WL 2095468, *4 (D. Minn. 2006), affd, 226 Fed.Appx. 613 (8th Cir. 2007) (affirming summary judgment because plaintiff failed to prove a re-test of his urine sample would have or could have produced a result different from the original test).
Mere speculation will not defeat a motion for summary judgment, and conclusory allegations, improbable inferences, and unsupported speculation are insufficient to create a genuine issue of material fact. See Wolfe v. Quad-Area Community Action Agency, Inc., 2022-0203 (La. App. 1 Cir. 9/16/22), 352 So.3d 992, 995, writ not considered, 2022-01625 (La. 1/11/23), 352 So.3d 562. Causation must be established beyond the point of speculation. Smeltzer, 2006 WL 2095468 at *4. Thus, because Mr. Bass has provided no evidence to support his speculative allegation that Mr. Guariscos negligent collection of his hair sample caused a false positive drug test for marijuana, we conclude the trial court correctly granted summary judgment in this case. Accordingly, we need not address TOMs argument that summary judgment is also appropriate as to the breach element of Mr. Basss negligence claim. See Williams, 2016 WL 770376 at *3 (noting that a negative answer to any of the inquires of the duty-risk analysis results in a determination of no liability).
CONCLUSION
For the foregoing reasons, we affirm the trial courts February 15, 2023 judgment, granting the motion for summary judgment filed by Convenient Care, L.L.C. d/b/a Total Occupational Medicine, and dismissing all of Brady Basss claims against Convenient Care, L.L.C. d/b/a Total Occupational Medicine. We assess costs of this appeal to Brady Bass.
AFFIRMED.

After the trial court dismissed Mr. Basss claims against Dr. Barnett, Mr. Bass filed a first amended petition naming Jerome Cooper, D.O., as a defendant, identifying him as DISAs Medical Review Officer. Mr. Basss claims against Dr. Cooper are not at issue in this appeal.

. On January 27, 2017, eleven days after Mr. Basss first hair sample was taken, J&B Industries collected a different sample of Mr. Basss hair, which returned a negative result for marijuana.
5
. Notwithstanding Mr. Basss failure to raise these issues, we note that, in Bass I, this Court determined the trial court properly dismissed Mr. Basss defamation claim therein, because there was no unprivileged publication to a third party and also properly dismissed his negligence per se claims because the Louisiana Drug Testing statute, Department of Transportation regulations, HIPAA, SAMHSA, and PHMSA guidelines did not apply to Mr. Basss claims. See Bass I, 318 So.3d at 921-923. Accord Russo v. International Drug Detection, L.L.C., 18-93 (La. App. 5 Cir. 5/30/18), 250 So.3d 1100, 1104 (finding SAMHSA regulations do not apply to hair drug testing and the Louisiana Drug Testing statute did not apply to a plaintiff employed in the exploration, drilling, or production of oil and gas in Louisiana).

. The Legislature recently amended La. C.C.P. art. 966, but those amendments are not applicable to this appeal. See 2023 La. Acts No. 317, § 1 (eff. Aug. 1, 2023), and 2023 La. Acts No. 368, § 1 (eff. Aug. 1, 2023); Jones v. Illinois Cent. R.R. Co., 2023-0457 (La. App. 1 Cir. 11/3/23), 378 So.3d 104, 106, n.2. Accordingly, we apply the version of La. C.C.P. art. 966 in effect on February 6, 2023, the date of the summary judgment hearing herein.
7
. Mr. Bass also filed the affidavit of Dana Way, a forensic scientist and chemist, in opposition to TOMs motion for summary judgment. After Mr. Bass filed his opposition, TOM filed a reply memorandum objecting to Ms. Ways affidavit as inadmissible summary judgment evidence. TOM argued the trial court should not consider Ms. Ways expert opinion regarding TOMs sample collection process. At the summary judgment hearing, the trial court heard argument on the issue and then granted TOMs objection, finding Ms. Ways affidavit failed to comply with La. C.C.P. art. 967 and contained conclusory opinions based on incomplete facts.After Mr. Bass appealed, TOM filed a motion with this Court to strike Ms. Ways affidavit from the appellate record. This Court denied the motion but noted that physical inclusion of the affidavit in the appellate record would not necessarily result in this Courts consideration of the affidavit on the merits of TOMs motion for summary judgment. Brady Bass v. DISA Global Solutions, Inc., et al., 2024 CA 0024 (La. App. 1 Cir. 3/13/24) (unpublished action). Because we affirm this summary judgment on a lack of evidence regarding the cause in fact element of Mr. Basss claim, we need not address Ms. Ways affidavit, which only addresses alleged errors in TOMs collection process and contains no discussion or opinion regarding the cause in fact of Mr. Basss positive drug tests.
8
. In an earlier affidavit included in the summary judgment record, Mr. Buffington attested that Mr. Basss positive hair sample tests “more likely than not reflect external contamination at the point of collection,” but gave no factual basis.
