Hair testing is gaining recognition as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record for alcohol and drugs by encapsulating biomarkers within the fibers of the growing hair strand. When collected near the scalp, hair can reveal up to a roughly 3-month window for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and straightforward to transport.
A 1.5-inch segment of approximately 200 hair strands (around the size of a #2 pencil) closest to the scalp will obtain 100mg of hair, the optimal sample size for screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advisable. We recommend using a jeweler’s scale to weigh the sample. If scalp hair is unavailable, a similar quantity of body hair can be used. When mentioning head hair, we specifically refer to scalp hair. Body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four major steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial processing of a sample into a laboratory’s system. It involves confirming that the sample was sealed and transported properly, assigning a random LAN (Laboratory Accessioning Number), and completing any outstanding data entry not covered by an electronic chain of custody system.
Screening entails an initial rapid assessment for drugs of abuse. While Screening is an economical approach to exclude drug use in most samples, a positive screen necessitates confirmation to be valid in legal settings. Any samples that show presumptive positive results in Screening require secondary confirmation.
If a sample shows presumptive positives during the Screening phase, additional hair is taken from the initial sample and prepped for Extraction. During this phase, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging technique to undertake.
Confirmation of any positive Screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed before confirmation as necessary. The comprehensive lab process, from Accessioning to Confirmation, is reviewed under the CAP (College of American Pathologists) Hair designation and matches the accreditation to ISO / IEC 17025 standards.
