Hair testing has gained recognition as an effective approach for uncovering use of drugs and alcohol. Hair strands act as a timeline by preserving biomarkers within their fibers, documenting long-term alcohol and drug usage. When cut near the scalp, hair samples can offer an estimation of a 3-month window for detecting alcohol and drugs. Collecting hair is straightforward, fairly resistant to tampering, and convenient to transport.
A 1.5-inch section consisting of roughly 200 hair strands (approximately the girth of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal quantity for testing and verification. For EtG, additional tests, and/or assessments exceeding 10 panel tests, a 150mg specimen is advised. It is suggested to measure the sample using a jeweler’s scale. If head hair is not available, a similar amount of body hair may be utilized. In reference to head hair, it denotes only scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug tests involves four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage wherein a sample is processed into a laboratory's system. This step ensures the sample was adequately sealed and sent, generates a unique LAN (Laboratory Accessioning Number), and finalizes any other data input not included through an electronic chain of custody process.
Screening performs a preliminary rapid test for abuse of substances. While it is an affordable method to exclude drug usage in the majority of samples, a positive screen requires confirmation to be valid for legal proceedings. Samples yielding presumptive positive results during Screening necessitate further confirmation.
In instances where a sample returns a presumptive positive during Screening, additional hair is obtained from the original specimen for the Extraction phase. At this point, drugs are drawn from hair at a significantly reduced concentration compared to other techniques (e.g., urine or oral fluid), thus making hair drug screening the most challenging methodology to implement.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are prepped and cleansed before confirmation as necessary. The entire procedure from Accessioning to Confirmation is thoroughly evaluated following both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
