Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair acts as a long-term recorder of alcohol and drug usage by locking in biomarkers within the growing hair strand's fibers. If collected near the scalp, hair can offer up to a 90-day detection period for alcohol and drugs. Hair collection is straightforward, less susceptible to adulteration, and easily transferred for analysis.
A sample measuring 1.5 inches containing about 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is optimal for screening and validation. For EtG, additional analyses, and/or tests exceeding 10 panels, 150mg of the sample is advised. It is suggested to weigh the sample with a jeweler’s scale. In the absence of scalp hair, an equivalent quantity of body hair can be gathered. Reference to head hair pertains solely to scalp hair, while body hair includes other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result consists of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary process where a sample is entered into a laboratory's system. This step includes confirming that the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data input not supplied by an electronic chain of custody system.
Screening is a preliminary evaluation for drug misuse. Although Screening is an economical method to exclude drug usage for most samples, a positive result necessitates confirmation to be valid in legal proceedings. Samples that test presumptively positive in Screening require further confirmation.
Should a sample test presumptively positive during the Screening phase, additional hair is extracted from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at a considerably lower concentration than in other methodologies (e.g., urine or oral fluid), rendering hair drug screening the most challenging method to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples with presumptive positives are cleansed before confirmation if necessary. The comprehensive laboratory procedure from Accessioning to Confirmation is subject to review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
