What was done
This is a narrative review describing analytical advances and toxicological applications of hair analysis for drug detection in clinical, forensic, pre-employment, and doping contexts compared with traditional biological matrices.
What was found
No quantitative data or diagnostic accuracy metrics are reported in the abstract. The review notes that hair analysis extends the drug detection window to weeks, months, or years, is noninvasive, and is less vulnerable to specimen adulteration or substitution compared to urine testing.
Why it matters
Hair testing provides an extended retrospective detection window, offering a complementary matrix to standard urinalysis for documenting drug exposure over longer time horizons.
Limits
The abstract presents no quantitative results, sample sizes, or systematic search criteria. It does not address potential confounders such as external contamination, cosmetic hair treatments, or racial and hair pigmentation differences in drug incorporation.
