Hair analysis has gained recognition as an effective means for identifying alcohol and drug consumption. Hair acts as a secure reservoir for identifying substances by capturing markers within its fibers. When gathered near the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. Hair is easy to obtain, relatively hard to tamper with, and simple to transport.
A section measuring 1.5 inches consisting of around 200 hair strands (approximating the size of a #2 pencil) adjacent to the scalp delivers 100mg of hair, which is optimal for testing. For EtG, add-ons, and/or analyses exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for weighing the sample. If scalp hair can't be obtained, an equal quantity of body hair can be used. By head hair, we mean scalp hair exclusively, while body hair indicates all other types (facial, axillary, etc.).
Process Overview
The laboratory handling of a drug test outcome entails four key phases: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step of introducing a sample into the lab's workflow. This procedure checks if the sample was properly sealed and delivered, assigns a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry not provided by an electronic chain of custody system.
Screening is an initial rapid evaluation for substances. Although Screening economically eliminates drug use on many samples, a positive test must be validated to be legally acceptable. Samples indicating a presumptive positive in Screening need a subsequent confirmation.
If a specimen shows a presumptive positive during Screening, more hair is pulled from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at a concentration much smaller than other methods (e.g., urine or oral fluid), making hair drug testing exceptionally challenging.
Confirming any positive result is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives undergo washing before confirmation if necessary. Each phase from Accessioning to Confirmation is examined under the CAP (College of American Pathologists) Hair designation and follows ISO / IEC 17025 standards.
