Hair analysis has gained recognition as an instrumental method for identifying substance and alcohol usage. Hair offers a prolonged history of alcohol and other substances by embedding biomarkers within the fibers of the developing hair strand. When taken close to the scalp, hair can provide approximately a 3-month detection timeframe for alcohol and other substances. Hair collection is straightforward, relatively challenging to tamper with, and simple to transport.
A 1.5-inch segment comprising about 200 hair strands (roughly equivalent to the thickness of a #2 pencil) nearest the scalp will yield 100mg of hair, the preferred sample size for both screening and confirmation. For EtG, additional tests, and/or tests exceeding 10 panels, a sample size of 150mg is advised. It's recommended to measure the sample using a jeweler’s scale. Should scalp hair be absent, a comparable quantity of body hair may be used. When discussing head hair, it specifically refers to scalp hair. Body hair pertains to all other hair categories (facial, axillary, etc.).
Process Overview
The laboratory evaluation of a drug test result encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial integration of a sample into a laboratory's system. This step involves ensuring the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry that isn't provided by an electronic chain of custody system.
Screening involves a preliminary rapid assessment for commonly abused drugs. Although Screening offers a cost-effective means of eliminating drug usage across most samples, a positive screen necessitates confirmation for court admissibility. Samples that yield a presumptive positive during Screening require further confirmation.
If a sample yields a presumptive positive during the Screening phase, more hair is extracted from the original sample and prepared for Extraction. In this phase, drugs are extracted from hair at a significantly lower concentration compared to other methodologies (such as urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are cleansed prior to confirmation if necessary. The entire laboratory process from Accessioning to Confirmation undergoes evaluation under the CAP (College of American Pathologists) Hair designation, as well as adherence to ISO / IEC 17025 standards.
