Hair testing is recognized as an effective approach for uncovering drug and alcohol consumption. Through hair, a historical record of substances like alcohol and drugs is obtained by capturing biomarkers within the strands as they grow. Collecting hair close to the scalp grants a detection period for alcohol and drugs of around three months. The procedure of hair collection is straightforward, challenging to tamper with, and uncomplicated for transport.
Obtaining a 1.5-inch segment, approximately 200 hair strands (similar in size to a #2 pencil) from nearest the scalp results in a 100mg sample, which is optimal for both screening and confirmation. When dealing with EtG, additional tests, or tests exceeding 10 panels, a specimen of 150mg is advised. We recommend using a jeweler’s scale for weighing. If head hair is absent, a comparable quantity of body hair may be used. Head hair specifically refers to scalp hair, whereas body hair encompasses other types (e.g., facial, axillary).
Process Overview
The laboratory processing of drug test outcomes entails four critical stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning incorporates the initial handling of a sample into the lab’s system. This process verifies the sample’s proper sealing and shipping, assigns a Laboratory Accessioning Number (LAN), and completes any additional data entry missing from an electronic chain of custody system.
Screening provides a preliminary assessment for substances of abuse. While it is a cost-efficient method for excluding drug use in most samples, a positive result from Screening demands a confirmation to be legally credible. Samples showing presumptive positives in Screening must undergo subsequent confirmation.
In instances where a sample tests presumptively positive during Screening, extra hair is extracted from the original sample for the Extraction stage. In this phase, drugs are isolated from hair with lower concentrations than other techniques (e.g., urine or oral fluid), creating a challenge in hair drug screening execution.
Any confirmed positive from Screening undergoes verification via GC/MS, GC/MS/MS, or LC/MS/MS. Necessary washing of presumptive positive samples is conducted before confirmation. The entire laboratory workflow from Accessioning to Confirmation is subject to review under CAP (College of American Pathologists) Hair designation and accredited to ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: The term "hair follicle tests" is frequently utilized, but the test actually examines the hair strand, not the follicle underneath the scalp.
