Hair tests are now viewed as a significant method for identifying drug and alcohol consumption. Hair offers a prolonged account of alcohol and other substance use by capturing biomarkers in the strands as they grow. Collected from near the scalp, hair samples can reveal alcohol and drug presence for up to roughly three months. Hair is easy to gather, hard to modify, and convenient to transport.
Collecting a 1.5-inch section consisting of roughly 200 hair strands (equivalent to a #2 pencil thickness) closest to the scalp provides 100mg of hair, which is the optimal quantity for both screening and confirmation. For EtG, add-on analyses, or tests exceeding 10 panels, 150mg of specimen is advisable. We suggest weighing the sample with a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair may be used. When we mention head hair, we are specifically discussing scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The main laboratory processes for handling a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within a lab’s network. This comprises verifying the sample's seal and shipment, assigning a random LAN (Laboratory Accessioning Number), and finalizing any extra data input absent from an electronic chain of custody system.
Screening involves an initial rapid review for drug substances. While it is a cost-efficient way to dismiss drug use in most samples, a positive result in Screening requires confirmation to hold up in legal proceedings. Samples flagged as presumptively positive in Screening demand a further verification.
For samples deemed presumptively positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. This step involves extracting drugs from hair at concentrations much lower than other methods (e.g., urine or oral fluid), which is why hair drug screening is considered the most challenging method to conduct.
Confirmations of any positive results from Screening are performed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo a cleansing prior to confirmation, if applicable. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair criteria along with ISO / IEC 17025 accreditation.
