Hair analysis is increasingly regarded as an effective method for identifying drug and alcohol consumption. The hair serves as a repository of historical data for alcohol and drug intake by capturing biomarkers within the strands as they grow. When clipped near the scalp, it can offer a detection timeline of roughly up to three months for various substances. Collecting hair is straightforward, somewhat resistant to tampering, and convenient to transport.
A hair sample of 1.5 inches comprising roughly 200 strands (around the diameter of a #2 pencil) close to the scalp yields 100mg, which is ideal for preliminary and confirmatory assessments. For EtG, additional tests, and tests extending beyond 10 panels, 150mg is advised. It is suggested to weigh the sample using a jeweler’s scale. In cases where scalp hair is inaccessible, an equivalent quantity of body hair may be used. "Head hair" pertains solely to scalp hair, while "body hair" includes all other categories of hair (facial, axillary, etc.).
Procedure Summary
The key phases in laboratory processing for drug testing include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial integration of a specimen into a laboratory’s system. This step entails confirming the sample's proper sealing and shipment, allocating a random LAN (Laboratory Accessioning Number), and concluding any extra data recording not covered by an electronic chain of custody framework.
Screening offers an initial swift assessment for substance abuse. Although it proves economical for ruling out drug use in most samples, a positive screen requires confirmation to hold up in court. Any specimens that appear positive in the Screening stage necessitate further confirmation.
Should a screening indicate a potential positive result, additional hair from the original sample undergoes Extraction. Here, substances are extracted from the hair at substantially lower concentrations compared to other methods (e.g., urine or saliva), highlighting the complexity of hair drug testing.
Verification of any positive screen is carried out using GC/MS, GC/MS/MS or LC/MS/MS technologies. Presumed positive samples undergo cleansing prior to confirmation if needed. The entire laboratory sequence from Accessioning to Confirmation is subject to reviews under both the CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
