Hair tests are recognized as a highly effective method for identifying drug and alcohol consumption. The hair captures a historical record of substances in its strands by embedding biomarkers. A sample taken from near the scalp can offer a detection span of roughly three months for various substances. Collecting hair is straightforward, relatively resistant to tampering, and easily transported.
A sample measuring 1.5 inches consisting of approximately 200 strands (similar to a #2 pencil in thickness) from near the scalp weighs 100mg, which is ideal for analysis. For EtG, additional tests, or those exceeding 10 panels, a 150mg sample is suggested. We advise using a jeweler’s scale to measure the sample. In the absence of scalp hair, an equivalent amount of body hair can be used. References to head hair pertain solely to scalp hair. Body hair encompasses all other types, such as facial or axillary hair.
Process Overview
The primary stages in a lab's drug testing process include Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab's system. This step covers ensuring the proper sealing and shipping of the sample, allocating a unique LAN (Laboratory Accessioning Number), and completing any extra data entry absent in an electronic chain of custody.
Screening acts as a preliminary assessment for substance abuse. While it's cost-efficient for dismissing drug use in most cases, any positive screens need confirmation for legal acceptance. Presumed positive samples identified during Screening require a follow-up confirmation.
Should a sample test positive at the Screening stage, more hair is taken from the initial batch for Extraction. Here, substances are extracted at significantly lower concentrations than other methods (like urine or saliva), making hair testing particularly intricate.
Confirmations of positive results are executed via GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positives undergo washing before confirmation. The entire procedure, from Accessioning to Confirmation, is scrutinized under the standards of both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation.
