Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. By entrapping biomarkers within the strands, hair offers a prolonged overview of substance use. Sampling near the scalp, hair can identify alcohol and drug presence for up to 3 months. Collection is straightforward, tampering is tricky, and transportation is hassle-free.
A 1.5-inch collection comprising roughly 200 hair strands (similar to a #2 pencil's diameter) closest to the scalp yields 100mg, ideal for testing. For EtG, supplementary tests, and tests exceeding 10 panels, 150mg is suggested. Measuring with a jeweler’s scale is advised. If scalp hair can't be sourced, equivalent body hair serves as an alternative. When discussing head hair, it pertains to scalp strands alone. Body hair includes all other varieties (facial, axillary, etc.).
Process Overview
In the laboratory analysis of a drug test, four crucial phases take place: Accessioning, Screening, Extraction, and Confirmation.
Accessioning marks the sample's entry into the lab's system. This encompasses verifying the sample's integrity upon receipt, generating a random LAN (Laboratory Accessioning Number), and filling in any data gaps not covered by an electronic chain of custody system.
Screening offers a preliminary assessment for substance misuse. Although Screening is economical, positive results necessitate confirmation for legal validity. Any samples showing potential positives in Screening mandate further confirmation steps.
For samples marked as potentially positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drug compounds are extracted at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), highlighting the complexities of hair drug screening.
Confirmation of a presumptive positive requires GC/MS, GC/MS/MS, or LC/MS/MS. Positive samples undergo washing before Confirmation if needed. Each laboratory phase from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation.
