Navigating False Positives in Drug Tests: The Riboflavin and Vitamin B Conundrum

- **Riboflavin (Vitamin B2) Influence:**

  - Molecular similarity to certain drugs can trigger false positives in immunoassay-based drug tests.

  - Commonly found in multivitamin supplements, Riboflavin's structure can cross-react with drug test assays.

- **Vitamin B12 and False Positives:**

  - Vitamin B12, a B-vitamin, can alter urine composition, leading to potential confusion in drug tests.

  - Metabolic breakdown of B-vitamins may produce compounds resembling drug metabolites, causing misleading outcomes.

- **Cautionary Measures:**

  - Individuals undergoing drug tests should disclose supplement use to testing authorities.

  - Confirmatory tests like GC-MS or LC-MS can accurately identify substances, distinguishing false positives from true positives.

Understanding these dynamics empowers individuals to navigate drug tests confidently, ensuring accurate results while maintaining essential vitamin intake.
