Hair testing has become recognized as a robust method for identifying drug and alcohol consumption. Hair offers an extended history of substance use by embedding biomarkers within the strands as they grow. When obtained near the scalp, hair can detect alcohol and drugs for up to roughly three months. Hair is easy to gather, relatively hard to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of around 200 strands (comparable to the width of a #2 pencil) near the scalp yields 100mg, the ideal amount for analysis. For EtG, add-ons, and tests exceeding 10 panels, a sample of 150mg is advised. We suggest utilizing a jeweler’s scale to measure the sample. If scalp hair can’t be acquired, a similar volume of body hair may be used. References to head hair specifically mean scalp hair, while body hair includes all other types (such as facial or axillary).
Process Overview
The processing of a drug test in a lab involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial step where a sample is processed into the laboratory system. This includes checking that it was properly sealed and transported, assigning it a unique LAN (Laboratory Accessioning Number), and finishing any extra data entry not covered by an electronic custody chain.
Screening is a preliminary check for substance misuse. While it's economical for ruling out drug use in most cases, a positive result here needs confirmation for legal acceptance. Any sample that tests positive in Screening requires further verification.
Should a sample appear positive during Screening, more hair is extracted from the original sample for the Extraction phase. Drugs are isolated from hair at lower concentrations than in other methods (e.g., urine or saliva)—hence, hair drug testing is the most challenging analysis to conduct.
Confirmation of positive results from Screening is conducted through GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing positive are washed before confirmation if needed. The complete process from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
