Hair testing is recognized as an effective means for identifying drug and alcohol consumption. Hair offers a comprehensive timeline of substance use, capturing biomarkers within the strands as the hair grows. When sampled near the scalp, hair can indicate drug and alcohol usage over an approximate 3-month span. It's easy to collect, relatively hard to tamper with, and convenient for shipping.
A sample of 1.5 inches consisting of around 200 hair strands (comparable to the size of a #2 pencil) nearest the scalp provides 100mg of hair, which is optimal for both screening and confirmation. For EtG, additional testing, or panels exceeding 10, 150mg is suggested. It's advisable to use a jeweler’s scale for weighing the specimen. If scalp hair isn't available, the equivalent amount of body hair can be used. References to head hair mean scalp hair only, while body hair encompasses other types (such as facial, axillary, etc.).
Process Overview
There are four major stages in laboratory drug test processing: Accessioning, Screening, Extraction, and Confirmation.
Accessioning denotes the process of the sample's initial integration into a lab's system. This step ensures proper sealing and shipment of the sample, assigns a Laboratory Accessioning Number (LAN) at random, and completes data entry beyond what might be captured by an electronic custody system.
Screening represents a preliminary evaluation for substances of abuse. While Screening serves as an economical filter for excluding drug usage across the majority of samples, any screened positive results must be verified to hold up in court. Samples deemed presumptively positive in Screening must undergo further confirmation.
Presumptive positives from the Screening lead to additional hair extraction and preparation for the Extraction phase. Here, drug compounds are drawn out from the hair at a much more reduced concentration compared to other methods (e.g., urine or oral fluid), making hair drug screening notably challenging.
Confirmatory analysis of any positive screen is executed through methods like GC/MS, GC/MS/MS, or LC/MS/MS. Essential washing of presumptive positive samples is performed prior to confirmation. The complete lab process, from Accessioning to Confirmation, adheres to standards set by both the CAP (College of American Pathologists) for Hair and ISO/IEC 17025 accreditation.
