Hair testing is now regarded as a potent mechanism for uncovering drug and alcohol consumption. Hair captures biomarkers in the fibers of the hair strand as it grows, providing a comprehensive history of alcohol and other drugs. When collected near the scalp, hair can reveal a detection window of up to three months for alcohol and other drugs. Hair is simple to collect, somewhat resistant to tampering, and easy to transport.
A sample of 1.5 inches comprising approximately 200 strands of hair (about the diameter of a #2 pencil) closest to the scalp provides 100mg of hair, which is the optimal sample for screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, 150mg of the specimen is advised. We recommend using a jeweler’s scale for weighing the specimen. If head hair isn't available, an equivalent quantity of body hair might be used. When we talk about head hair, we mean only scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four fundamental steps in the laboratory processing of a drug test result comprise Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial processing of a sample into the laboratory’s system. This involves confirming that the sample was correctly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any necessary data entry that is not part of an electronic chain of custody system.
Screening includes an initial rapid assessment for drugs of abuse. While Screening is an economical way to rule out drug usage on most samples, a positive screen must be confirmed for legal acceptance. Samples showing presumptive positives in Screening require additional confirmation.
If a sample is presumptively positive at the Screening stage, further hair is extracted from the initial specimen and prepared for Extraction. During this phase, drugs are drawn from hair at a lower concentration compared to other methods (that is to say, urine or oral fluid), underscoring why hair drug screening is among the toughest methodologies to execute.
Confirmation of any positive screening result is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are washed as necessary prior to confirmation. The full laboratory process, from Accessioning to Confirmation, undergoes review according to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
