Hair analysis is recognized as an effective method for identifying substance and alcohol use. Hair captures a long-term record of drug and alcohol usage by embedding biomarkers into its strands. When taken near the scalp, hair can offer a detection period of up to about 90 days. Hair is easy to gather, relatively hard to tamper with, and convenient for transportation.
A sample measuring 1.5 inches consisting of nearly 200 hair strands (roughly the thickness of a #2 pencil) near the scalp provides 100mg of hair, the optimal amount for evaluation. For EtG, add-ons, or over 10-panel tests, a 150mg sample is advised. We suggest using a jeweler’s scale to measure the sample. If scalp hair isn't available, the equivalent volume of body hair can be used. Head hair pertains only to scalp hair, while body hair includes other types (such as facial, underarm, etc.).
Process Overview
The primary steps in laboratory processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initializing of a sample in a lab's system. This step ensures that the sample was correctly sealed and sent, allocates a random LAN (Laboratory Accessioning Number), and finalizes any additional data entry not managed by an electronic chain of custody mechanism.
Screening entails an initial quick examination for drugs of abuse. Screening is an economical approach to exclude drug usage in most samples; however, a positive screen needs verification to be court-admissible. Samples that are presumptively positive in Screening require subsequent confirmation.
Should a sample show presumptive positives during Screening, additional hair is taken from the original sample and readied for Extraction. In this phase, drugs are extracted from hair at far lower concentrations than with other methods (such as urine or saliva), making hair drug testing exceptionally challenging.
Confirmation of any positive Screening outcomes is performed through GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples are washed if necessary. The entire process from Accessioning to Confirmation is regulated under CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards.
