Hair analysis is recognized as a robust approach for identifying substance misuse. Hair offers a prolonged record of alcohol and drug use by embedding biomarkers within the fibers of the growing strand. When harvested near the scalp, hair can reveal a detection span of up to three months for substances. The collection of hair is straightforward, comparatively hard to tamper with, and easy to transport.
A sample measuring 1.5 inches comprising around 200 strands (roughly matching a #2 pencil's thickness) nearest to the scalp yields 100mg of hair, ideal for analysis. For EtG, additional testing, or screenings beyond 10 panels, a specimen of 150mg is advised. We suggest using a jeweler's scale to weigh the sample. Should scalp hair be unavailable, a similar amount of body hair may be gathered. When we mention head hair, we specifically mean scalp hair. Body hair includes every other kind (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with logging a sample into the lab’s system, verifying it was sealed and sent correctly, assigning a random Laboratory Accessioning Number (LAN), and handling any extra data entry not covered by an electronic tracking system.
Screening is an initial quick assessment for substance misuse. Although Screening is an efficient way to exclude drug usage for most samples, a positive result requires subsequent confirmation to be valid in legal proceedings. Any samples testing presumptively positive during Screening need further confirmation.
If a sample tests presumptively positive at Screening, additional hair is taken from the initial sample for Extraction. At this phase, drugs are extracted from hair at a significantly lower concentration than in other methods (like urine or oral fluid), hence hair drug testing presents the greatest challenge.
Confirming any positive test result is done using GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicated as presumptively positive are washed prior to confirmation if necessary. The entire lab procedure, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair certification and the ISO / IEC 17025 standards accreditation.
