Hair testing has emerged as an effective instrument for identifying drug and alcohol consumption. Hair records a lengthy history of alcohol and drug usage by embedding biomarkers within the strands. When gathered from areas near the scalp, hair can show drug and alcohol presence for as much as about 90 days. Hair is straightforward to collect, hard to tamper with, and straightforward to transport.
A sample measuring 1.5 inches with around 200 strands (similar in size to a #2 pencil) near the scalp will provide approximately 100mg, which is optimal for both screening and confirmation. For EtG, add-ons, or for tests exceeding 10 panels, an amount of 150mg is suggested. It's advisable to use a jeweler’s scale to weigh the specimen. If scalp hair isn't available, a similar quantity of body hair can be used. When mentioning head hair, it pertains solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The four principal steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning encompasses the initial integration of a sample into the lab's system. This process checks that the sample was properly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any missing data entry not available via electronic chain of custody.
Screening consists of a preliminary rapid assessment for drug presence. Although Screening is a budget-friendly method for eliminating drug use in most samples, any positive findings must be confirmed for legal purposes. Presumptively positive samples in Screening require further validation.
If a sample tests as presumptively positive during Screening, extra hair is sourced from the original sample for the Extraction phase. During this phase, drugs are removed from hair at a significantly lower concentration than methods using urine or oral fluid. This complexity makes hair drug screening the toughest methodology.
Confirmation of any positive screening outcome is administered using GC/MS, GC/MS/MS, or LC/MS/MS. Any samples found positive are cleansed before confirmation as needed. The entire series from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair standards and the ISO / IEC 17025 accreditation.
