Hair analysis is now widely regarded as an effective method for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug use by embedding biomarkers within the strands as they grow. When taken from near the scalp, it allows for a detection period of up to 3 months for alcohol and drugs. Hair is easy to collect, challenging to tamper with, and is conveniently shipped.
A 1.5-inch portion consisting of roughly 200 strands of hair (similar in size to a #2 pencil) near the scalp yields 100mg, which is the preferred sample amount for screening and confirmation. For EtG, additional tests, and tests exceeding 10 panels, a sample weighing 150mg is suggested. We advocate measuring the sample on a jeweler’s scale. For instances when scalp hair is missing, the same quantity of body hair can be used. “Head hair” specifically refers to scalp hair, while “body hair” includes all other types of hair (e.g., facial, axillary).
Process Overview
The lab processing of a drug test involves four primary phases: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is entered into a lab’s system. This step verifies the proper sealing and shipping of the sample, assigns a unique LAN (Laboratory Accessioning Number), and concludes any data input missing from an electronic chain of custody system.
Screening provides a preliminary examination for drugs. Though Screening is cost-efficient for ruling out drug use in most samples, any positive results must be confirmed for legal admissibility. Any samples showing a presumptive positive in Screening necessitate a follow-up confirmation.
Upon a presumptive positive result in Screening, further hair is extracted from the original sample for Extraction. Here, drugs are drawn out from hair at concentrations notably lower than those utilized in alternative methods (such as urine or oral fluids), explaining why hair drug testing is a complex technique to conduct.
Confirmation of positive screening results is achieved using GC/MS, GC/MS/MS, or LC/MS/MS. Samples that are presumptive positive are prepped with washing if needed. The complete laboratory procedure, from Accessioning to Confirmation, undergoes examination under both the CAP (College of American Pathologists) Hair category and compliance with ISO / IEC 17025 standards.
