Hair testing is recognized as an effective method for identifying drug and alcohol use. It provides a comprehensive timeline by capturing biomarkers within the fibers of the growing hair. A sample taken near the scalp offers approximately a 3-month detection period for substances like alcohol and other drugs. Hair collection is straightforward, challenging to tamper with, and easy to transport.
A sample of 1.5 inches consisting of about 200 hair strands (comparable to the thickness of a #2 pencil) nearest to the scalp yields 100mg, which is ideal for both screening and confirmation. For EtG, additional tests, and those beyond 10 panels, it's advised to collect 150mg of the hair. We suggest using a jeweler’s scale for weighing. If scalp hair isn't accessible, an equivalent volume of body hair can be used. By head hair, we refer exclusively to scalp hair, while body hair includes all other types (such as facial or axillary hair).
Process Overview
The method for processing a laboratory drug test result comprises four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where a sample is introduced into the laboratory’s system. It verifies that the sample was properly sealed and shipped, assigns a LAN (Laboratory Accessioning Number), and manages any extra data entry not covered by an electronic chain of custody.
Screening starts with a preliminary check for drugs of abuse. Though cost-effective, any positive screen must be confirmed to hold up in court. Samples with presumptive positive screens must undergo additional confirmation.
For samples indicated as presumptively positive during Screening, further hair is extracted for the Extraction phase. Here, substances are isolated from hair at lower concentrations compared to other methods (like urine or oral fluid), making hair drug testing the most challenging method to execute.
Confirmation of positive screening outcomes is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives undergo washing before confirmation as necessary. The complete process from Accessioning to Confirmation is reviewed under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
