Hair testing is increasingly viewed as an effective means for detecting drug and alcohol consumption. It captures long-term drug and alcohol usage histories by entrapping biomarkers within the strands as the hair grows. Hair samples taken near the scalp can offer up to roughly a three-month detection window for substances. Collecting hair is straightforward, challenging to adulterate, and easy to transport.
A 1.5-inch sample consisting of nearly 200 strands (around the girth of a #2 pencil) closest to the scalp provides 100mg of hair, which is ideal for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the specimen is advised. Using a jeweler's scale to weigh the sample is suggested. If scalp hair is not available, an equivalent quantity of body hair can be gathered. When mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses other types of hair (such as facial, axillary, etc.).
Process Overview
The lab processing of a drug test is composed of four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial processing into the lab's system, ensuring it was sealed and sent correctly, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that an electronic chain of custody system might not supply.
Screening is a preliminary rapid assessment for drugs of abuse. While it offers a cost-efficient method to rule out drug use for most samples, a positive screen requires confirmation for legal admissibility. Samples showing presumptive positives in Screening will undergo further confirmation.
Should a sample indicate presumptive positivity during Screening, more hair is extracted from the initial sample to prepare for Extraction. This step involves extracting drugs from hair at concentrations much lower than other methods (such as urine or oral fluid), highlighting the complexity of hair drug testing.
Positive results from screening are confirmed using methods like GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are washed ahead of confirmation if necessary. The comprehensive lab process from Accessioning to Confirmation is thoroughly reviewed under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
