Can Elevate by Avantera Cause a False Positive UDS for Cocaine Metabolites?
No, Elevate by Avantera should not cause a false positive urine drug screen for cocaine metabolites based on its ingredient profile, as none of its components are known to cross-react with cocaine metabolite immunoassays.
Understanding Cocaine Metabolite Testing
Urine drug screens for cocaine specifically detect benzoylecgonine, the primary metabolite of cocaine, which has a urinary half-life of 6-8 hours and can be detected for approximately 24-48 hours after cocaine use 1. The standard cut-off value for a positive result is typically 300 ng/mL 1.
- Benzoylecgonine represents approximately 16-39% of the administered cocaine dose depending on route of administration 2
- This metabolite is highly specific to cocaine use and is the gold standard marker for cocaine exposure 3, 2
Known Causes of False Positives
Based on comprehensive guideline reviews, the medications and substances documented to cause false-positive drug screens do not include typical nootropic or supplement ingredients 4, 5:
Documented False Positive Causes:
- Bupropion (antidepressant) can cause false positives for amphetamines or cocaine on immunoassay screens 5
- Pseudoephedrine (decongestant) causes false-positive amphetamine results 4
- Dextromethorphan (cough suppressant) can cause false positives 4
- Poppy seeds cause false-positive opiate results 4
What Does NOT Cause Cocaine False Positives:
- Methylprednisolone and other corticosteroids do not interfere with standard urine drug screening 4
- Standard nootropic ingredients (amino acids, vitamins, herbal extracts) are not documented to cross-react with cocaine metabolite assays 4, 5
Critical Considerations for Interpretation
If a positive cocaine metabolite result occurs while taking Elevate:
- The positive result is likely a true positive, not attributable to the supplement 4
- Request confirmatory testing using gas chromatography-mass spectrometry (GC-MS), which is the gold standard and definitively distinguishes true cocaine use from false positives 1, 4, 6
- Review all other medications and substances, including over-the-counter products, as the source of any unexpected result 4, 5
Important Clinical Pitfalls
- Standard immunoassay screens are designed as presumptive tests only and have known limitations in specificity due to cross-reactivity 4, 5
- However, cocaine metabolite testing (benzoylecgonine) is highly specific compared to other drug screens because the metabolite structure is unique to cocaine 1, 2
- Never make consequential clinical decisions based solely on immunoassay results without confirmatory GC-MS testing when results are unexpected 4, 5
- Medicinal cocaine use (such as in nasal surgery) will cause positive results for 24-72 hours 7
Recommendation for Healthcare Providers
Obtain a complete medication and supplement history before interpreting any positive drug test, but recognize that dietary supplements like Elevate are extremely unlikely to cause cocaine metabolite false positives 4, 5. If a positive result occurs, proceed directly to confirmatory GC-MS testing rather than attributing the result to the supplement 4, 6.
