Seeing hair testing as an effective method for identifying drug and alcohol consumption has become common. By embedding biomarkers within the strands of growing hair, it offers a prolonged history of alcohol and drug use. When taken from near the scalp, hair can present a detection window extending roughly three months for alcohol and drugs. The simplicity of collection, resistance to tampering, and ease of transportation characterize hair testing.
Collecting a 1.5-inch sample of approximately 200 hair strands, akin to a #2 pencil in size, nearest to the scalp yields 100mg of hair, making it the preferred amount for analysis. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's suggested to weigh the sample using a jeweler’s scale. If no scalp hair is on hand, an equivalent quantity of body hair may be taken. Referring to head hair only pertains to scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
Drug test processing in the lab is comprised of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, samples undergo initial processing into a lab's system. This involves checking that the sample was properly sealed and transported, assigning it a random LAN (Laboratory Accessioning Number), and finishing any necessary data entry not covered by an electronic chain of custody system.
Screening provides a preliminary evaluation for drugs of abuse. While Screening efficiently eliminates drug usage for many, any positive result needs confirmation for court acceptance. Samples testing presumptively positive in Screening necessitate secondary confirmation.
Should a sample be presumptively positive in Screening, additional hair is drawn from the original sample and readied for Extraction. At this phase, drugs are removed from hair in concentrations lower than other methods (for instance, urine or oral fluid), underlining the challenge of hair drug screening.
Confirmation of any positive screening output takes place via GC/MS, GC/MS/MS or LC/MS/MS. Needed positive samples are cleansed before confirmation. The comprehensive laboratory sequence from Accessioning to Confirmation abides by both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
