Hair testing has emerged as an effective method for identifying drug and alcohol use. Hair offers an extended timeline of substance use by embedding biomarkers within the growing hair strand. Collected near the scalp, hair can reveal drug and alcohol use for up to 90 days. The collection process is straightforward, tough to tamper with, and easy to transport.
A 1.5-inch segment comprising approximately 200 hair strands (roughly the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for analysis. For EtG add-ons and/or tests surpassing 10 panels, 150mg is advised. It's suggested to measure the sample with a jeweler’s scale. In the absence of scalp hair, a comparable amount of body hair can be acquired. "Head hair" refers strictly to scalp hair. "Body hair" encompasses other types (facial, axillary, etc.).
Process Overview
The drug testing laboratory process involves these four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is incorporated into a lab’s system. This step ensures the sample is appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and completes any necessary data entry missing from an electronic chain of custody system.
Screening is the preliminary assessment for drugs of abuse. Despite its effectiveness and cost-efficiency in ruling out drug presence in most cases, a positive screening needs further verification to hold up in court. Samples with a presumptive positive result in Screening need a secondary confirmation.
In case of a presumptive positive result at the Screening stage, additional hair is taken from the initial sample for Extraction. Here, drugs are isolated from hair at much lower concentrations compared to other methods like urine or oral fluid, which makes hair drug testing one of the most challenging procedures.
Confirmation of any positive result from Screening is done through GC/MS, GC/MS/MS, or LC/MS/MS. Necessary presumptive positive samples are cleansed before confirmation. The entire process, from Accessioning to Confirmation, meets the CAP (College of American Pathologists) Hair designation as well as ISO / IEC 17025 standards.
