Hair analysis has become recognized as a significant method for detecting the presence of drugs and alcohol. Hair can capture a prolonged history of drug and alcohol consumption by encasing markers within the fibers of the strand as it grows. If taken near the scalp, hair can offer a detection window of up to roughly three months for these substances. Gathering hair samples is straightforward, challenging to tamper with, and convenient for shipping.
A 1.5-inch segment of approximately 200 hair strands (similar in size to a #2 pencil) nearest to the scalp equates to 100mg, which serves as the perfect sample amount for analysis. For extended tests like EtG, add-ons, or those exceeding 10 panels, using 150mg of the sample is advisable. We suggest weighing the specimen with a jeweler's scale. In the absence of scalp hair, a proportional amount of body hair can be collected. When mentioning head hair, we specifically mean scalp hair. Body hair encompasses all other variants (such as facial or axillary).
Process Overview
The laboratory processing of a drug testing result involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step of entering a sample into the lab’s system. This phase ensures the sample is properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and fills in any data not captured by an electronic custody chain.
Screening acts as a preliminary inspection for drug presence. This economical method can eliminate drug usage in most samples, but any positive screening must be verified for legal credibility. Samples flagged as presumptively positive in Screening must undergo further confirmation.
For a presumptively positive specimen in Screening, additional hair is drawn from the sample and prepared for Extraction. This phase extracts drugs from the hair at significantly lower levels than other approaches (such as urine or oral fluids), rendering hair drug testing a complex procedure.
Verification of any positive screening output is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive undergo cleaning prior to confirmation as required. The end-to-end laboratory procedure, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair standards and meets ISO/IEC 17025 accreditation.
