Hair testing is increasingly recognized as an effective method for identifying drug and alcohol use. Hair offers a comprehensive history of substances by embedding biomarkers within the strands of growing hair. When obtained near the scalp, hair can reveal up to a 3-month detection period for drugs and alcohol. It is straightforward to collect, relatively resistant to tampering, and easy to transport.
A sample measuring 1.5 inches with around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is optimal for screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. Utilize a jeweler’s scale for weighing the specimen. In the absence of scalp hair, a comparable amount of body hair can be gathered. Head hair refers exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test outcome involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial incorporation of a sample into the laboratory system. It involves ensuring the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any further data entry not provided by an electronic chain of custody system.
Screening checks for drugs quickly and cost-effectively to exclude drug use on most samples; however, positive screens need confirmation to be legally sound. Samples showing a positive result in Screening require secondary confirmation.
For presumptively positive samples in Screening, additional hair is extracted from the original sample for Extraction. In this phase, drugs are extracted from hair at a lower concentration than other methods (e.g., urine or oral fluid), thus making hair drug screening the most challenging method to carry out.
Confirmation for any positive screening result involves GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed prior to confirmation as necessary. The entire process from Accessioning to Confirmation is reviewed under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
