Hair testing is recognized as a robust method for identifying drug and alcohol consumption. Hair acts as a repository, preserving a drug and alcohol history by capturing biomarkers in the hair strand's fibers. When obtained close to the scalp, hair can provide an approximate 3-month detection timeframe for substances. Collecting hair is straightforward, somewhat resistant to tampering, and convenient for shipping.
A 1.5-inch section containing roughly 200 hair strands (similar in size to a #2 pencil) from near the scalp will yield 100mg of hair, which is optimal for screening and validation. For EtG tests, add-ons, or tests involving more than 10 panels, 150mg of the sample is advisable. It's suggested to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent amount of body hair can be gathered. Note that "head hair" specifically means scalp hair, while "body hair" refers to all other hair types (e.g., facial, axillary).
Process Overview
The laboratory processing of a drug test result includes four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial processing of a sample into a laboratory's system. This step ensures the sample is properly sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not managed by an electronic chain of custody system.
Screening serves as a preliminary drug check. While Screening is a cost-efficient method for ruling out drug use in most samples, a positive result must be confirmed to be valid in legal contexts. Any samples that screen positive require further confirmation.
If a sample screens positive, more hair is extracted from the initial collection and set for Extraction. In this procedure, drugs are isolated from hair at lower concentrations than in other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Positive screening outcomes are confirmed via GC/MS, GC/MS/MS, or LC/MS/MS. Any samples with presumptive positives undergo washing prior to confirmation when needed. The entire process, from Accessioning to Confirmation, adheres to CAP (College of American Pathologists) Hair designation and meets ISO / IEC 17025 accreditation standards.
