Hair analysis is recognized as an effective method for identifying substance usage of drugs and alcohol. The hair can chronicle a long-term history by embedding biomarkers within its developing strands. When acquired near the scalp, hair can reveal consumption data for alcohol and drugs within a timeframe of about three months. Collecting hair is straightforward, challenging to tamper with, and convenient for transportation.
A sample measuring 1.5 inches, with approximately 200 strands (roughly the thickness of a #2 pencil) closest to the scalp, will yield 100mg, which is the optimal amount for both preliminary and confirmatory testing. For EtG, additional screenings, and tests exceeding 10 panels, it's advisable to collect 150mg of the sample. Utilizing a jeweler’s scale for weighing the specimen is suggested. If scalp hair isn't accessible, a comparable quantity of body hair can be used. When discussing head hair, it specifically pertains to scalp hair; body hair includes all other varieties (such as facial or axillary).
Process Overview
The fundamental steps in processing a drug test result in the lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the introduction of the sample into the laboratory’s workflow. This process ensures that the sample remains sealed and is transported correctly, allocates a unique LAN (Laboratory Accessioning Number), and addresses any absent data from the electronic chain of custody procedures.
Screening serves as a preliminary assessment to detect substance misuse. Although Screening is a cost-efficient method to discount drug usage in many cases, a positive screen result requires confirmation for legal validity. Any screens that indicate a presumptive positive result necessitate an additional confirmation.
In cases where a sample is presumptive positive during Screening, additional hair is extracted and prepped for the Extraction phase. Here, drugs are isolated from hair at lower concentrations versus other methods (such as urine or saliva), marking hair drug tests as the most demanding to carry out.
A positive screening requires confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed if needed before confirmation. The holistic process from Accessioning to Confirmation is reviewed in compliance with the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation standards.
