The use of hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. Hair captures a long-term history by embedding biomarkers within the hair strands as they grow. When taken near the scalp, hair provides up to a 3-month detection period for alcohol and drugs. Hair is straightforward to collect, difficult to tamper with, and easy to transport.
A 1.5-inch segment comprising about 200 strands of hair (comparable to the diameter of a #2 pencil) closest to the scalp yields 100mg of hair, which is ideal for analysis. For EtG add-ons and/or panels over 10, 150mg is advised. It's advisable to weigh the hair using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be utilized. References to head hair pertain to scalp hair only, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where the sample is entered into the lab’s system. This involves ensuring the sample was securely sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and filling in any extra data entry needed outside of an electronic chain of custody system.
Screening is an initial scan for drugs of abuse. While Screening offers a cost-effective method to exclude drug use in most samples, a positive screen must be validated for court acceptance. Any samples flagged as presumptive positives during Screening need a follow-up confirmation.
Should a sample return a presumptive positive during Screening, additional hair is extracted from the original sample and prepared for Extraction. Drugs are isolated from hair at far lower concentrations than in other testing methods like urine or oral fluid, making hair drug testing the most challenging to execute.
Positive screening confirmations are carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed, if necessary. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation.
