Hair analysis has become recognized as a significant method for detecting alcohol and drug usage. Hair retains a comprehensive record of drugs and alcohol by embedding biomarkers within the strands as they grow. When taken from near the scalp, hair offers an approximately 3-month detection period for alcohol and drugs. The collection process is straightforward, tampering is challenging, and shipping is efficient.
A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the size of a #2 pencil) near the scalp will yield 100mg of hair, which is an optimal amount for testing and verification. For EtG add-ons or tests with more than 10 panels, a specimen size of 150mg is advised. It's recommended to weigh the hair on a jeweler’s scale. If no scalp hair is available, a similar quantity of body hair can be used. References to head hair pertain strictly to scalp hair. Body hair includes all other types (such as facial, axillary, etc.).
Process Overview
The primary steps in the lab processing of drug test results are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step involving the processing of a sample into the lab's system. This step ensures the sample is sealed and shipped correctly, assigns a LAN (Laboratory Accessioning Number), and enters any additional data not covered by an electronic chain of custody system.
Screening is a preliminary rapid test for drug presence. Though Screening is a cost-efficient method to exclude drug usage in most samples, a positive result requires confirmation to be valid in legal proceedings. Samples that test tentatively positive during Screening require a secondary confirmation.
Should the sample test tentatively positive during the Screening phase, additional hair is extracted from the initial sample for the Extraction phase. Here, drugs are extracted from hair at much lower concentrations than in other methods (like urine or oral fluid), making hair drug testing one of the most technically challenging methods.
Positive results from Screening are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Each presumptively positive sample is washed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
