Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair tracks a prolonged record of alcohol and drug intake by capturing biomarkers in its fibers as it grows. When taken close to the scalp, hair offers a detection period of up to roughly three months for alcohol and drugs. Its collection is straightforward, difficult to alter, and simple to mail.
A sample measuring 1.5 inches, with around 200 hair strands (approximately the thickness of a #2 pencil) near the scalp, yields 100mg of hair, which is the preferred amount for screening and validation. For tests like EtG, add-ons, and those greater than 10 panels, a 150mg sample is advised. We suggest using a jeweler’s scale for weighing. If scalp hair is unavailable, a comparable quantity of body hair may be used. The term "head hair" specifically refers to scalp hair, while "body hair" includes all other types (facial, axillary, etc.).
Process Overview
The primary stages in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the sample's initial input into a lab system. It involves verifying the sample’s proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data not provided by an electronic chain of custody.
Screening serves as a preliminary rapid check for drug abuse. While Screening can rule out drug use for most samples economically, a positive screen must be confirmed for courtroom admissibility. Presumptive positive samples require a secondary check.
If Screening's results are presumptively positive, additional hair is taken from the initial sample for Extraction. During this process, drugs are removed from the hair at concentrations much lower than other methods (e.g., urine or oral fluids), making hair drug screening highly challenging.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all presumptive positive samples are washed as necessary. Throughout, the process from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
