The detection of drugs and alcohol through hair testing is now regarded as a highly effective approach. Hair captures long-term usage data by embedding biomarkers within its growing fibers. When sampled from the scalp, hair can reveal a drug and alcohol history stretching back about three months. The collection process is straightforward and the sample is tough to tamper with, plus it’s convenient to mail.
A 1.5-inch segment consisting of approximately 200 hair strands (roughly the size of a #2 pencil) from near the scalp offers 100mg of hair, which is considered the optimal amount for effective screening and confirmation. For EtG assessments, additional tests, and/or those exceeding 10 panels, a quantity of 150mg is preferable. We advise using a jeweler’s scale for measuring the sample. In cases where scalp hair is absent, a proportional amount of body hair can be utilized. When discussing head hair, it's specific to scalp hair. Body hair covers all other types (facial, axillary, etc.).
Process Overview
The drug testing process in the lab consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the step where a sample is initially integrated into the lab's system. This process involves ensuring the sample's seal and shipment were intact, assigning it a random Laboratory Accessioning Number (LAN), and filling in any data not provided by an electronic chain of custody protocol.
Screening acts as a preliminary evaluation for the presence of drug abuse. Although cost-effective for eliminating drug usage concerns in most samples, any positives from this stage must be validated for court use. Presumptive positives in Screening necessitate a further confirmation step.
For samples deemed presumptively positive during Screening, additional hair strands are taken from the original sample for the Extraction phase. Here, drugs are extracted at lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug testing a particularly challenging procedure.
All positive findings from screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, samples that are presumptively positive are cleansed based on requirements. The entire procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 standard accreditation.
