Hair analysis is recognized as an effective method for identifying the usage of substances such as drugs and alcohol. The hair strands capture biomarkers, offering a long-term record of substance consumption. A sample taken near the scalp can reveal substance use over approximately a three-month period. The collection process is straightforward, it's relatively secure from tampering, and shipping is uncomplicated.
A sample measuring 1.5 inches, containing about 200 strands of hair (comparable to the width of a #2 pencil) and weighing around 100mg, is ideal for both screening and confirmation. For tests like EtG add-ons or those exceeding 10 panels, a 150mg sample is preferable. The best practice is to weigh the sample using a jeweler’s scale. In instances where scalp hair isn't available, a comparable amount of body hair can be collected. 'Head hair' strictly refers to scalp hair, whereas 'body hair' includes all other hair types (such as facial, underarm, etc.).
Process Overview
The drug testing laboratory process encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
In the Accessioning phase, the sample is entered into the lab system, confirming its proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and completing any necessary data entry not covered by an electronic chain of custody system.
Screening provides a preliminary evaluation for drug presence. While cost-effective for ruling out drug use in many samples, a positive screen requires confirmation to be legally valid. Samples showing presumptive positives in Screening must undergo further confirmation.
Should Screening indicate a presumptive positive, additional hair from the initial sample is processed for Extraction. Drugs are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), illustrating the complexity of hair drug analysis.
Confirmed positive results are validated through GC/MS, GC/MS/MS or LC/MS/MS methods. Presumptive positive samples are washed if necessary before confirmation. The entire testing process, from Accessioning to Confirmation, is critically assessed under the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
