Hair testing is emerging as an effective means for identifying drug and alcohol consumption. The fibers within hair strands capture biomarkers, offering a prolonged snapshot of alcohol and drug exposure. A strand harvested close to the scalp can reveal drug and alcohol presence for around a 3-month timeframe. Hair is straightforward to gather, relatively hard to tamper with, and convenient to transport.
A segment of hair measuring 1.5 inches and consisting of roughly 200 strands (comparable to the width of a #2 pencil) nearest to the scalp will provide 100mg of hair, which is the ideal sample quantity for screening and confirmation. To perform EtG, additional tests, or analysis exceeding 10 panels, 150mg of the sample is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair is not accessible, a similar quantity of body hair can be used. The term "head hair" exclusively refers to scalp hair, while "body hair" includes any other type (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four crucial steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary integration of a sample into a lab's database. This step involves checking the proper sealing and shipping of the sample, assigning a unique LAN (Laboratory Accessioning Number), and entering any supplementary details not covered by an automated chain of custody mechanism.
Screening involves a quick preliminary analysis for drug abuse indicators. Though it’s a cost-effective approach to negate drug use for most samples, any positive screening result requires confirmation to stand in legal proceedings. Samples with a tentative positive outcome in Screening necessitate further verification.
If a sample is tentatively positive during Screening, more hair is retrieved from the original sample for the Extraction phase. At this stage, drugs are extracted from hair at a concentration much lower than other methods (e.g., urine or oral fluid), which makes hair drug testing one of the most challenging techniques to execute.
GC/MS, GC/MS/MS, or LC/MS/MS techniques are employed for the Confirmation of any positive screening outcomes. All samples testing positive undergo necessary washing before confirmation. Every step from Accessioning to Confirmation is conducted adhering to the guidelines of both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
