Hair testing has emerged as a key method for identifying drug and alcohol usage. Hair offers an extended history of alcohol and drug intake by sequestering biomarkers within the hair strands as they grow. When taken near the scalp, hair can offer a detection period of around 3 months for alcohol and other drugs. Its collection is straightforward, it's challenging to tamper with, and it ships easily.
A sample measuring 1.5 inches, consisting of roughly 200 strands (similar to the thickness of a #2 pencil) nearest the scalp, yields 100mg of hair, which is ideal for both screening and confirmation. For EtG, test add-ons, or tests exceeding 10 panels, 150mg of the sample is suggested. Using a jeweler's scale to weigh the specimen is advised. If no scalp hair is available, a similar quantity of body hair can be collected. Here, head hair specifically means scalp hair, while body hair includes all other kinds of hair (like facial or axillary hairs).
Process Overview
The primary steps in processing a drug test in the lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial entry of a sample into the lab's system. This step ensures the sample's seal and shipment were intact, assigns a random LAN (Laboratory Accessioning Number), and finishes any further data entry missing from an electronic chain of custody system.
Screening is a preliminary examination for substances of abuse. While Screening serves as a cost-effective means to exclude drug use for most samples, any positive results must be verified for court acceptance. Samples showing positive results in Screening require subsequent confirmation.
For samples showing possible positive results in Screening, additional hair is extracted from the initial sample for the Extraction phase. This process extracts drugs from hair in much lower concentrations than in other analyses (such as urine or oral fluids), making hair drug screening more intricate to conduct.
Confirmation of any positive screening result is carried out using methods like GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are cleansed before confirmation as required. From Accessioning through Confirmation, the full lab process is evaluated under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.
