Hair analysis has grown to be recognized as an effective method for identifying drug and alcohol consumption. Hair captures a record of alcohol and drug intake over time by holding biomarkers within the hair strand as it grows. Collected near the scalp, it allows for up to a three-month window of detection for alcohol and drugs. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.
A section of hair measuring 1.5 inches with about 200 strands (equivalent to a #2 pencil) near the scalp offers 100mg of hair, ideal for both screening and confirming results. For EtG, additional panels, or tests exceeding 10 panels, a collection of 150mg is advised. Using a jeweler’s scale to weigh the sample is recommended. If scalp hair is unavailable, equivalent body hair may be used. In reference to head hair, we mean only scalp hair. Body hair includes all other types such as facial and axillary hair.
Process Overview
The laboratory processing of a drug test result includes four main steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves entering a sample into a lab’s system. This step includes ensuring the sample was properly sealed and sent, assigning a Laboratory Accessioning Number (LAN), and completing any missing data entry not covered by electronic chain of custody systems.
Screening entails a quick initial check for drugs of abuse. Although it’s a cost-effective way to eliminate the possibility of drug use in most samples, a positive screen must be confirmed for court acceptance. Samples showing presumptive positive results in Screening require additional confirmation.
If presumptively positive in the Screening stage, the sample undergoes additional hair collection for Extraction. This step extracts drugs from hair at a lower concentration compared to other methods like urine or oral fluid, enhancing the complexity of hair drug screening.
Confirmation of positive screening results employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples showing presumptive positives are washed before confirmation as needed. The complete process from Accessioning to Confirmation is verified under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
