Hair analysis has emerged as a significant method for identifying drug and alcohol consumption. The hair retains long-term data on alcohol and drug use thanks to the biomarkers embedded within the hair shaft. Collecting hair near the scalp can provide up to an approximate three-month detection period for these substances. It's easy to collect, challenging to tamper with, and simple to transport.
A sample of hair measuring 1.5 inches and consisting of about 200 strands (about the size of a #2 pencil) close to the scalp provides 100mg, which is the perfect amount for testing and confirmation. For EtG or elevated testing panels above 10, a 150mg specimen is suggested. It's advisable to measure the sample on a jeweler’s scale. If scalp hair isn't available, an equivalent body hair sample can be used. Head hair refers strictly to scalp hair, while body hair encompasses other hair types such as facial and axillary hair.
Process Overview
There are four essential stages in laboratory processing of a drug test: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails initially processing a sample into the lab’s information system. It involves checking that the sample was shipped correctly sealed, assigning it a random LAN (Laboratory Accessioning Number), and completing any other data entry not covered by an electronic chain of custody.
Screening is a preliminary check for substances of abuse. Although it's a cost-effective method for ruling out drug use for the majority of samples, a positive result in Screening must be validated to hold up in legal settings. Any samples that are presumptively positive in Screening need additional confirmation.
If the Screening stage indicates a presumptive positive, more hair will be taken from the initial sample for the Extraction stage. Drugs are at this stage extracted from hair in much lower concentrations compared to other methods like urine or oral fluid, making hair drug testing notably challenging.
Positive screening results are confirmed using GC/MS, GC/MS/MS or LC/MS/MS. Before Confirmation, all presumptive positives need washing as needed. The review of the entire lab process from Accessioning to Confirmation is done under both the CAP (College of American Pathologists) Hair designation and accreditation according to ISO / IEC 17025 standards.
