Hair tests have gained recognition as an effective method for detecting drug and alcohol use. Hair retains a comprehensive history of alcohol and drug consumption by capturing biomarkers within the strands as they grow. When obtained near the scalp, hair offers approximately a three-month detection timeframe for alcohol and drugs. Collecting hair is straightforward, a bit challenging to tamper with, and easy to transport.
A 1.5-inch segment consisting of around 200 hair strands (comparable to a #2 pencil) nearest to the scalp provides 100mg of hair, an ideal sample size for both screening and confirmation. For EtG, additional, and/or tests exceeding 10 panels, 150mg of hair is advisable. It's suggested to use a jeweler’s scale to measure the sample. In the absence of scalp hair, an equivalent amount of body hair can be gathered. When referring to head hair, it strictly implies scalp hair. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four key steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample undergoes initial processing into a lab’s system. This process ensures the sample is properly sealed and shipped, allocates a random LAN (Laboratory Accessioning Number), and completes any supplementary data entry absent from an electronic chain of custody system.
Screening conducts a preliminary, quick assessment for drugs of abuse. Although Screening is an economical method to exclude drug usage in most cases, a positive result necessitates confirmation to be legal in court. Samples that are presumptively positive in Screening necessitate a secondary confirmation.
If a sample is presumptively positive during Screening, additional hair is extracted from the initial sample for Extraction. In this stage, drugs are extracted at substantially lower concentrations from hair than other methods (e.g., urine or oral fluid), making hair drug screening the most complex methodology to execute.
Confirmation of any screening positives is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive specimens are cleaned before confirmation as required. The comprehensive lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.
