Hair analysis has emerged as an effective technique for identifying drug and alcohol consumption. Hair retains a prolonged record of alcohol and drug intake by capturing biomarkers within the strands of the hair as it grows. Hair taken from near the scalp offers a detection period of up to roughly three months for substances. Collecting hair is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches composed of around 200 hair strands (comparable to a #2 pencil thickness) taken closest to the scalp yields 100mg of hair, which is ideal for testing and verification. For supplementing EtG, extending panels beyond 10, or additional analyses, 150mg of the sample is advisable. It's best to use a jeweler’s scale for weighing the specimen. If no scalp hair is present, the equivalent quantity of body hair may be utilized. The term head hair describes only scalp hair. Body hair includes any other hair types (like facial or axillary hair).
Process Overview
The drug test process in a lab encompasses four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into the lab’s system. This process includes ensuring the sample's seal and shipment are correct, allocating a random LAN (Laboratory Accessioning Number), and completing data input if an electronic chain of custody system doesn’t provide it.
Screening acts as an initial, rapid assessment for substance abuse. It is a cost-efficient method to exclude drug usage in the majority of cases, though positive findings must undergo confirmation to be valid in legal settings. Presumptively positive cases in Screening require further verification.
Should a sample test presumptively positive during Screening, additional hair is extracted from the original sample and processed for Extraction. This stage involves isolating drugs from hair in significantly lower concentrations than methods like urine or oral fluid testing; hence, performing hair drug screening is notably more challenging.
Any positive screening outcome undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methodologies. Samples that are presumptively positive are cleansed before confirmation if necessary. The entire process, from Accessioning to Confirmation, is examined under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.
