Hair analysis is now acknowledged as a potent method for detecting drug and alcohol usage. Hair offers a prolonged history of alcohol and drug use by embedding biomarkers in the strands of growing hair. Collected close to the scalp, hair can reveal up to a 90-day window of detection for alcohol and drug consumption. It is easy to collect, challenging to tamper with, and straightforward to transport.
A 1.5-inch sample with approximately 200 strands of hair (comparable to a #2 pencil) taken near the scalp provides 100mg of hair, which is the optimal sample size for both screening and confirmation. For EtG, add-ons, and tests exceeding 10 panels, 150mg of hair is suggested. It's advisable to weigh the hair using a jeweler's scale. If scalp hair isn't available, a similar amount of body hair can be used. The term head hair specifically refers to scalp hair, while body hair includes all other types (beard, axillary, etc.).
Process Overview
The drug test analysis in a lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first step where the sample is entered into the lab's system. This step verifies that the sample is sealed and shipped correctly, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing information not included in the electronic chain of custody system.
Screening serves as an initial swift assessment for drug abuse. Although Screening is an economical approach for ruling out drug use in most samples, a positive result requires confirmation to be valid in a legal setting. Any samples that appear positive in Screening must undergo a secondary confirmation.
When a sample tests positive during Screening, additional hair is extracted from the initial specimen for the Extraction phase. Drugs are isolated from hair at far lower concentrations than in other methods (such as urine or oral fluid), which makes hair drug testing one of the most intricate methods to execute.
Confirmation of a positive result from Screening is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are washed before confirmation if necessary. The complete lab process from Accessioning to Confirmation undergoes review following both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the skin.
