Hair examination is now regarded as a significant method for identifying drug and alcohol consumption. Hair captures a long-term history of alcohol and other substances by securing biomarkers within the strands of developing hair. When collected near the scalp, hair offers a detection window for alcohol and other drugs of up to about 3 months. It's easy to collect, relatively hard to tamper with, and simple to transport.
A sample of 1.5 inches comprising approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, the perfect sample for both screening and confirmation. For EtG, add-ons, and/or panels exceeding 10, a sample of 150mg is advisable. It's recommended to measure the specimen using a jeweler’s scale. If scalp hair can't be obtained, an equivalent quantity of body hair may be used. When mentioning head hair, it signifies scalp hair exclusively. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The four major steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This comprises verifying that the sample was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and inputting any supplementary data not supplied by an electronic chain of custody system.
Screening involves an initial rapid check for drug abuse. Even though Screening is a cost-efficient means to dismiss drug usage for most samples, a positive screen requires confirmation to be court-admissible. Any samples suspected positive in Screening require further confirmation.
If a specimen is suspected positive during the Screening stage, additional hair is taken from the original sample and made ready for Extraction. At this stage, drugs are extracted from hair at much lower concentrations than other methods (e.g., urine or oral fluid), marking hair drug screening as the most challenging technique to implement.
Confirmation of any positive Screening result occurs via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed as necessary before confirmation. The entire lab process from Accessioning through Confirmation is thoroughly reviewed under both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.
