Hair assessments are recognized as an effective means to uncover drug and alcohol consumption. Hair captures a prolonged record of substance use by containing biomarkers within the strands' fibers as they grow. When taken near the scalp, hair can offer a detection period of nearly three months for alcohol and drugs. Hair samples are straightforward to obtain, relatively hard to tamper with, and convenient to transport.
A 1.5-inch section including roughly 200 strands of hair (comparable to the thickness of a #2 pencil) when taken closest to the scalp yields 100mg of hair, which is optimal for both screening and verification. For EtG, additional testing, and/or panels exceeding 10, 150mg of hair is advised. It's recommended to measure the sample using a jeweler’s scale. If scalp hair isn't available, a similar quantity of body hair can be utilized. 'Head hair' pertains solely to scalp hair. 'Body hair' is used to describe all other types (facial, axillary, etc.).
Process Overview
There are four principal phases in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary processing of a specimen into a laboratory’s framework. It includes ensuring the sample was appropriately sealed and dispatched, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data documentation not supplied by an electronic chain of custody framework.
Screening involves a preliminary swift assessment for substance abuse. While Screening offers an economical approach to rule out most drug use cases, a positive result requires confirmation to be legally acceptable. Samples that test presumptively positive in Screening must undergo further verification.
Should a sample show a presumptive positive result at the Screening phase, additional hair is extracted from the initial sample for the Extraction stage. Here, drugs are isolated from hair at concentrations considerably lower than other methods (such as urine or oral fluid), defining why hair drug testing is among the most complex methodologies.
Confirmation of any positive Screening findings is carried out using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleansed prior to confirmation as necessary. The entire process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and adheres to ISO / IEC 17025 certifications.
