Hair analysis is now regarded as an effective means for detecting the use of drugs and alcohol. Hair captures a prolonged record of drug and alcohol use by preserving biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can indicate drug or alcohol usage for up to a roughly 3-month span. Hair is easy to collect, challenging to tamper with, and simple to transport.
A sample measuring 1.5 inches, consisting of roughly 200 hair strands (comparable in width to a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG, additional tests, and/or panels exceeding 10, a specimen of 150mg is advised. It's suggested to measure the specimen with a jeweler’s scale. In cases where scalp hair isn't available, an equivalent quantity of body hair can be collected. By head hair, we mean only scalp hair. Body hair encompasses all other types (such as facial, axillary, etc.).
Process Overview
The fundamental stages in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the sample’s initial introduction into the lab’s system. This phase includes confirming the sample was properly sealed and shipped, generating a random LAN (Laboratory Accessioning Number), and finishing any supplemental data entry not supplied by an electronic chain of custody system.
Screening offers a preliminary check for drugs of abuse. While Screening is a budget-friendly method to rule out drug use in most samples, a positive result must be confirmed for court admissibility. Any sample with a presumptive positive result in Screening requires a follow-up confirmation.
If a sample tests presumptively positive during Screening, additional hair is extracted from the initial sample for the Extraction process. Here, drugs are removed from hair at noticeably lower concentrations than in other methodologies (like urine or oral fluid), making hair drug screening the most challenging methodology to carry out.
Confirmation of a positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples that test presumptively positive are washed as needed before confirmation. The entire lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
