Hair testing is now considered a strong method for identifying drug and alcohol consumption. Hair offers an extended historical record of alcohol and other substances by encapsulating biomarkers within the fiber of the elongating hair strand. Collected from near the scalp, hair can present around a 90-day window of detection for alcohol and other substances. Hair collection is straightforward, somewhat hard to tamper with, and easily transportable.
A sample measuring 1.5 inches encompassing around 200 hair strands (similar to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, add-ons, or tests surpassing 10 panels, 150mg of the specimen is advised. It's suggested to use a jeweler’s scale for weighing the specimen. If scalp hair isn’t available, an equivalent body hair amount can be used. Head hair refers specifically to scalp hair. In contrast, body hair includes all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is where a sample is initially entered into a lab’s system. This step includes ensuring the sample was properly sealed and shipped, allocating it a random LAN (Laboratory Accessioning Number), and filling out any remaining data not entered by an electronic chain of custody system.
Screening offers a preliminary check for drug abuse. Screening serves as a low-cost technique to rule out drug usage in most samples, but a positive result needs confirmation to hold up in legal contexts. Samples that screen positively need further secondary confirmation.
If a specimen is positive in the Screening phase, extra hair comes from the initial sample and is set for Extraction. Drugs are extracted from hair in lower concentrations compared to urine or oral fluid, making hair drug screening a challenging methodology.
Confirmation for any positive result in screening is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleaned before confirmation as required. The complete laboratory procedure, from Accessioning to Confirmation, is inspected under both the CAP (College of American Pathologists) Hair designation and compliant with ISO / IEC 17025 standards.
