Hair testing is recognized as a significant method for pinpointing drug and alcohol consumption. Hair strands, due to their biological makeup, retain evidence of alcohol and various drugs by embedding biomarkers into their growing fibers. When samples are taken near the scalp, they can reveal drug and alcohol use for a period of up to three months. Collecting hair is straightforward, challenging to alter, and convenient for shipment.
A 1.5-inch segment consisting of roughly 200 hair strands (equivalent to a #2 pencil) nearest to the scalp secures 100mg of hair, which is the optimal quantity for analysis and verification. For EtG, additional tests, and/or examinations exceeding 10 panels, 150mg of hair is advised. It's advised to measure the sample using a jeweler’s scale. If scalp hair is inaccessible, a comparable quantity of body hair can be gathered. In discussing head hair, we mean scalp hair solely; body hair encompasses all remaining hair varieties (facial, axillary, etc.).
Process Overview
Four primary procedures take place in the lab analysis of a drug test, including Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial integration of a sample into the lab's framework. This encompasses ensuring the sample's secure sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and filling out any absent data not provided via an electronic chain of custody system.
Screening offers a rapid preliminary examination for substance misuse. Despite Screening being a cost-efficient approach to establish drug presence in most samples, a confirmed positive screen is necessary for court validity. Samples that appear positive during Screening require further confirmation.
If a sample emerges as presumptively positive during Screening, more hair is retrieved from the initial collection for the Extraction process. In this stage, narcotics are withdrawn from hair at notably lesser concentrations than other procedures (like urine or oral fluid), making hair drug testing highly complex.
Confirmation of any presumptive screening results utilizes GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples showing presumptive positivity undergo washing prior to confirmation if needed. From Accessioning to Confirmation, the comprehensive lab workflow is verified under the CAP (College of American Pathologists) Hair classification and compliance with ISO / IEC 17025 benchmarks.
Advantages of hair drug testing:
Limitations:
Note: Although commonly named "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
