Hair testing is now recognized as a potent instrument for detecting alcohol and drug use. It offers a prolonged history by embedding biomarkers within the hair strand fibers as they grow. When sampled near the scalp, hair can offer a detection span of up to three months for drugs and alcohol. Collecting hair is straightforward, somewhat hard to tamper with, and simple to transport.
A hair sample measuring 1.5 inches with approximately 200 strands (comparable to the thickness of a #2 pencil) located nearest to the scalp yields 100mg, the optimal quantity for screening and confirmation tests. For EtG, enhanced panels, and/or tests beyond 10 panels, 150mg of hair is advised. It is recommended to measure the sample on a jeweler’s scale. If scalp hair isn't available, an equal volume of body hair can be obtained. When referring to head hair, it implies scalp hair exclusively. Body hair includes all other hair types like facial, axillary, etc.
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first stage where a sample is processed into the lab's system. It includes confirming that the sample was properly sealed and sent, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not provided by an electronic chain of custody.
Screening is the preliminary rapid test for substance abuse. While Screening is economical for ruling out drug use in most samples, a positive result must be validated to be valid in court. Positive samples in Screening require a secondary confirmation.
Should a sample test positive in Screening, more hair is taken from the original sample and prepped for Extraction. Here, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), which makes hair drug screening the toughest method to perform.
Confirmation of a positive screening result is performed using GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples are cleaned before confirmation, if necessary. The lab process from Accessioning to Confirmation is reviewed according to the CAP (College of American Pathologists) Hair designation and complies with ISO / IEC 17025 standards.
