Hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. Through the capture of biomarkers in the fibers of developing hair strands, hair provides a long-term record of alcohol and drug use. When collected near the scalp, hair can reveal a detection timeframe of up to approximately 90 days for alcohol and drugs. Collecting hair is straightforward, relatively hard to adulterate, and convenient to ship.
A 1.5-inch section comprising about 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample size for both screening and confirmation. For additional EtG, add-ons, or tests exceeding 10 panels, it is advised to use 150mg of the sample. It is suggested to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a comparable volume of body hair can be collected. When mentioning head hair, it refers exclusively to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Procedure Summary
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary step of integrating a sample into the lab's framework. This step includes checking that the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any supplementary data input not handled by an electronic chain of custody system.
Screening provides an initial rapid assessment for drugs of misuse. Although Screening is a cost-efficient technique to eliminate drug usage in most samples, any positive results necessitate confirmation to be legally permissible. Any samples showing a presumptive positive in Screening must undergo secondary confirmation.
If Screening indicates a presumptive positive, additional hair from the initial sample is used for Extraction. In Extraction, drugs are retrieved from hair at concentrations lower than those in other methods (e.g., urine or oral fluid), making hair drug screening among the most challenging to perform.
Confirmation of a positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as required. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
