Hair testing is recognized as a robust method for detecting the presence of drugs and alcohol. Hair strands capture biomarkers within the growing fibers, offering a detailed record of alcohol and drug usage. When gathered near the scalp, hair can reveal up to an approximate 3-month detection timeline for both alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (equivalent to the thickness of a #2 pencil) nearest to the scalp provides 100mg of hair, considered the optimal quantity for both screening and confirmation. For EtG tests, add-ons, and/or tests exceeding 10 panels, a sample of 150mg is advised. It is recommended to use a jeweler’s scale for weighing the sample. Should scalp hair be absent, a comparable volume of body hair is acceptable. By head hair, we specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug testing result encompasses four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial handling of a sample within the lab’s framework. This process includes assurance that the sample has been securely sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and completing any further data input not already captured by an electronic chain of custody system.
Screening provides a preliminary assessment for drugs of abuse. Although Screening effectively rules out drug use in most samples, a positive result requires confirmation to be permissible in legal proceedings. Any samples flagged as presumptively positive during Screening necessitate additional confirmation.
If a sample is flagged as positive during the Screening phase, additional hair is retrieved from the original sample for Extraction. Here, drugs are extracted at concentrations significantly lower than other methods (like urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmed positive results from Screening are validated through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed as needed before confirmation. The comprehensive process, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
