Hair testing has become recognized as a potent method for detecting drug and alcohol consumption. Hair offers a detailed history of alcohol and drug exposure by encapsulating biomarkers within the strands as they grow. When taken close to the scalp, hair can reveal substance use for up to three months. This method is easy to administer, relatively tamper-proof, and simple to transport.
A sample of 1.5 inches, consisting of about 200 hair strands (roughly as thick as a #2 pencil) near the scalp provides 100mg of hair, which is perfect for screening and confirmation. For EtG and additional tests or those beyond 10 panels, a 150mg specimen is advised. It’s best to weigh the sample using a jeweler’s scale. If scalp hair is absent, an equivalent amount of body hair can be used. The term head hair specifically refers to scalp hair. Body hair denotes other hair types (such as facial and axillary).
Process Overview
The laboratory process of drug testing encompasses four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is integrated into the laboratory's system. This step ensures the sample is properly sealed and transported, assigns a LAN (Laboratory Accessioning Number), and completes data entry that is not covered by an electronic chain of custody.
Screening serves as a preliminary check for drug abuse, offering a cost-effective way to eliminate negative samples. However, a positive screen needs further Confirmation to be legally valid. Screened samples with a positive result necessitate a follow-up confirmation test.
For samples testing positive in the Screening stage, additional hair is extracted and prepared for the Extraction phase. This part of the process pulls drugs from hair at much lower concentrations than other testing methods (like urine or oral fluid), highlighting why hair drug testing is notably intricate.
Any positive result during Screening undergoes Confirmation through GC/MS, GC/MS/MS, or LC/MS/MS. All such samples are thoroughly washed before Confirmation if necessary. The entire testing procedure, from Accessioning to Confirmation, complies with CAP (College of American Pathologists) Hair standards and ISO/IEC 17025 accreditation.
