Testing involving hair is acknowledged as an efficient method for identifying the presence of drugs and alcohol. Hair captures indicators within its fibers, offering a retrospective account of substance use. When clipped near the scalp, it can reveal up to a 3-month span of drug and alcohol usage. The collection process of hair is straightforward, not easily tampered with, and convenient for transport.
A 1.5-inch portion consisting of around 200 hair strands, roughly matching the size of a #2 pencil, when sampled near the scalp, yields 100mg—ideal for analysis. For EtG, additional tests, or evaluations beyond 10 panels, a specimen weight of 150mg is advised. It is advisable to measure the sample using a jeweler's scale. If scalp hair is not accessible, an equal quantity of body hair can be utilized. References to head hair are specifically about scalp hair, whereas body hair encompasses all other varieties (facial, axillary, etc.).
Process Overview
The drug test laboratory procedures encompass four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample's initial entry into the laboratory's framework. This step includes ensuring the sample was correctly sealed and dispatched, assigning it a LAN (Laboratory Accessioning Number), and fulfilling any other data entry tasks not covered by an electronic chain of custody system.
Screening involves a preliminary assessment for drugs of abuse. While economic for ruling out drug presence in most samples, a positive result from Screening requires validation for court acceptance. Presumptive positives in Screening must undergo a subsequent confirmation.
When a sample tests presumptively positive during Screening, more hair is extracted from the original sample for Extraction. Drugs are isolated from hair at low concentrations, unlike other methodologies (e.g., urine or oral fluid), making hair drug screening particularly challenging.
Confirmation of positive screenings is performed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positives undergo cleansing prior to confirmation if necessary. The laboratory protocol from Accessioning to Confirmation is audited under both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation.
