Hair examination is increasingly recognized as a robust method for detecting drug and alcohol consumption. The strands of hair accumulate biomarkers within their fibers as they grow, providing a lengthy history of substance use. Samples taken from near the scalp can offer up to a three-month period for detecting alcohol and drugs. Collecting hair is straightforward, somewhat resistant to adulteration, and convenient for shipping.
A sample around 1.5 inches long, consisting of approximately 200 hair strands (similar in size to a #2 pencil) taken from the scalp, will yield roughly 100mg of hair, which is the perfect quantity for both screening and confirmation. For EtG testing, add-ons, and tests exceeding 10-panel, a recommendation of 150mg of the sample is suggested. It is best to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equal quantity of body hair can be used. When discussing head hair, it pertains solely to scalp hair. Body hair implies all other hair types (facial, axillary, etc.).
Process Overview
The fundamental stages in laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial incorporation of a sample into a lab’s system. This step ensures the sample was sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and finalizes any extra data entry omitted by an electronic chain of custody system.
Screening constitutes a preliminary rapid check for drug presence. While Screening is a cost-efficient method to exclude drug usage in the bulk of samples, any positive screen demands confirmation to be valid in judicial proceedings. Samples that return presumptively positive during Screening require a secondary confirmation.
If Screening results are presumptively positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are extracted from the hair at significantly lower concentrations than those encountered in other methodologies (e.g., urine or oral fluid), making hair drug screening a challenging methodology to conduct.
Confirmation of any positive screening results is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive specimens undergo washing prior to confirmation, if needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
