Hair testing is increasingly recognized as an effective method for identifying the consumption of drugs and alcohol. Hair offers a prolonged history of substance use by capturing biomarkers in the strands of hair as they grow. When taken from near the scalp, hair may reveal alcohol and drug use over a time span of up to about three months. The collection of hair is straightforward, not easily tampered with, and convenient to transport.
A sample measuring 1.5 inches with roughly 200 strands of hair (comparable to the size of a number 2 pencil) nearest to the scalp yields 100mg, which is the preferred amount for testing and verification. For EtG, additional tests, and/or for panels exceeding 10, it is advised to gather 150mg of the sample. A jeweler’s scale is recommended for weighing the sample. Should scalp hair be unobtainable, an equivalent amount of body hair might be collected. References to head hair pertain exclusively to scalp hair, while body hair encompasses all other hair types (like facial and axillary).
Process Overview
The process in a laboratory for testing drug samples involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial processing of a specimen within the laboratory framework. This step verifies proper sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and executes any additional data entry not supplied by an electronic chain of custody.
Screening is a preliminary assessment for drug presence. Though cost-effective as a preliminary filter, a positive screen necessitates confirmation before it can be deemed legally valid. Presumptive positives from Screening require ensuing confirmation.
Upon a presumptive positive result in Screening, additional hair is extracted from the original sample and prepared for Extraction. Here, drugs are withdrawn from hair at more minute concentrations than with other techniques (e.g., urine or oral fluids), thus making hair testing a challenging approach to implement.
All positive screens undergo confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. Any samples preliminarily positive are cleansed prior to confirmation as required. The laboratory process from Accessioning through to Confirmation is evaluated in line with the CAP (College of American Pathologists) Hair protocol and ISO / IEC 17025 standards of accreditation.
