Hair testing has emerged as an effective mechanism for identifying drug and alcohol consumption. Hair captures a prolonged timeline of drugs and alcohol by embedding biomarkers in the fibers of the hair strand as it grows. When taken near the scalp, it can offer up to around a 3-month detection period for substances. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch segment of roughly 200 hair strands (around the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the ideal amount for both screening and confirmation. For EtG, additional tests, and/or panels beyond 10, it is suggested to use 150mg of hair. We recommend using a jeweler’s scale to weigh the specimen. If scalp hair is not available, a similar volume of body hair can be collected. When mentioning head hair, we exclusively refer to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result primarily involves four stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial phase where the sample is integrated into the lab system. It involves ensuring that the sample is properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and finalizing any necessary data entry not covered by an electronic chain of custody system.
Screening involves a preliminary check for drugs of abuse. Although Screening is a cost-efficient means to eliminate drug use for most samples, a positive screen necessitates confirmation to be legally valid in court. All samples flagged as presumptively positive during Screening necessitate a secondary confirmation step.
When a sample tests presumptively positive in the Screening phase, additional hair is taken from the initial sample for Extraction. This step involves extracting drugs from hair at concentrations substantially lower than other methods (e.g., urine or oral fluid), making hair drug testing particularly challenging.
Confirmation of any positive results from Screening is performed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation as required. The complete lab process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair designation and compliance with ISO / IEC 17025 standards.
Advantages of hair drug testing:
Limitations:
Note: Commonly termed as "hair follicle tests", the analysis is conducted on the hair strand rather than the follicle beneath the scalp.
