Hair analysis has gained recognition as an effective method for identifying drug and alcohol usage. Hair captures a prolonged history of substance use by embedding biomarkers during hair growth. A sample taken near the scalp can offer an alcohol and drug detection period of approximately 3 months. Collecting hair is straightforward, has a low risk of tampering, and is simple to transport.
A 1.5-inch portion of about 200 hair strands (roughly the size of a #2 pencil) situated close to the scalp provides 100mg of hair, which is the optimal amount for both screening and confirmation. For EtG, additional tests, or examinations exceeding 10 panels, a specimen of 150mg is advised. We suggest using a jeweler's scale to measure the specimen. If scalp hair is scarce, an equal volume of body hair may be utilized. When mentioning head hair, we specifically mean scalp hair, while body hair encompasses all other types (such as facial and axillary hair).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is brought into the laboratory system. This step ensures the sample was properly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry required outside of an electronic chain of custody system.
Screening is the preliminary rapid assessment for drug substances. While it is a cost-efficient way to eliminate most samples for drug use, positive findings must be confirmed to hold up in court. Presumptive positive samples from Screening necessitate an additional confirmation.
When a sample tests positive during the Screening phase, extra hair is extracted from the original sample for the Extraction process. Drugs are extracted at lower concentrations from hair than with other methods (e.g., urine or oral fluid), which is why hair drug screening is notably challenging to execute.
Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Every presumptive positive sample undergoes a washing process before confirmation if necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
