Hair testing is now regarded as a significant method for detecting drug and alcohol consumption. Hair serves as a long-term record of alcohol and drug use by capturing biomarkers within the strands as it grows. When a sample is obtained near the scalp, hair testing offers upto a roughly three-month detection timeframe for alcohol and drug presence. Collecting hair is straightforward, somewhat resistant to tampering, and can be easily transported.
A 1.5-inch hair sample consisting of roughly 200 strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred amount for analysis and verification. For EtG, add-ons, or screenings exceeding 10 panels, a specimen size of 150mg is advised. It is suggested to measure the sample using a jeweler's scale. If head hair can't be collected, a similar amount of body hair is acceptable. "Head hair" strictly refers to scalp hair; "body hair" includes all other types (facial, armpit, etc.).
Process Overview
There are four primary stages in the laboratory processing of drug test samples: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the initial handling of a specimen into the lab's system. This process includes the authentication of proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry absent from an electronic chain of custody setup.
Screening carries out a preliminary and rapid assessment for abuse of drugs. Although Screening economically filters drug usage from most specimens, a positive result requires verification for court validity. Samples indicating presumed positivity in Screening necessitate additional confirmation.
When samples show presumed positives at the Screening phase, more hair is prepared from the original specimen for the Extraction process. At this step, lower concentrations of drugs are derived from hair compared to other methods (e.g., urine or oral fluids), making hair screening exceptionally challenging.
Confirming any positive screening involves GC/MS, GC/MS/MS, or LC/MS/MS. Each presumed positive sample is cleaned before confirmation if necessary. The entire lab routine from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair specialization and certified to ISO / IEC 17025 standards.
