Hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. By encapsulating biomarkers in the fibers of growing strands, hair reveals a long-term record of substance usage. Obtaining hair samples near the scalp can offer insights into roughly a three-month window of alcohol and drug consumption. Collecting hair is straightforward, less prone to tampering, and easy to transport.
A sample measuring 1.5 inches, containing around 200 hair strands (similar in size to a #2 pencil) from the scalp will yield 100mg, which is considered optimal for screening and confirmation. For EtG, additional tests, and tests beyond 10 panels, it's advisable to use 150mg of hair. Using a jeweler’s scale is recommended for weighing the specimen. In the absence of scalp hair, a similar quantity of body hair can be used. "Head hair" pertains specifically to scalp hair, whereas "body hair" includes all other hair (facial, axillary, etc.).
Process Overview
The four primary phases in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a lab’s system. This involves ensuring the sample is properly sealed, assigning a unique LAN (Laboratory Accessioning Number), and completing any supplementary data entry not captured by an electronic chain of custody.
Screening offers a preliminary assessment for drugs of abuse. Although Screening is an economical method for discounting drug use in most samples, a positive screen demands confirmation to be legally valid. Samples showing a presumptive positive in Screening require further confirmation.
When a sample shows a presumptive positive during Screening, additional hair is extracted from the initial specimen and readied for Extraction. In this step, drugs are isolated from hair at a lower concentration than other methods (such as urine or oral fluids), making hair drug screening a particularly challenging process.
Confirmation of any positive screening result is undertaken using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as needed. The complete lab process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair guidelines and the accreditation of ISO / IEC 17025 standards.
