Hair testing is recognized as an effective method for identifying drug and alcohol consumption. It provides a detailed, long-term history of substance use by encapsulating biomarkers in the fibers of growing hair strands. When sampled near the scalp, hair can offer a detection window of up to three months for alcohol and other drugs. The process of collecting hair is straightforward, with low risks of tampering, and it is easily transportable.
A 1.5-inch segment of approximately 200 hair strands (comparable to a #2 pencil's width) near the scalp yields 100mg, which is the preferred sample size for both screening and confirmation tests. For EtG, panels exceeding 10 tests, or add-ons, a specimen amounting to 150mg is suggested. It's advised to weigh the specimen with a jeweler's scale. In cases where scalp hair is unavailable, the equivalent amount of body hair can be used. References to head hair specifically indicate scalp hair, while body hair encompasses all other types such as facial and axillary hair.
Process Overview
The laboratory workflow of a drug test result encompasses Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into the laboratory’s system. This step verifies proper sealing and shipment of the sample, assigns a Laboratory Accessioning Number (LAN), and completes any data missing from an electronic chain of custody system.
Screening serves as an initial check for abusive drug use. While cost-effective for eliminating drug presence in most samples, a positive screen must undergo confirmation to be valid for court. Samples that test presumptively positive during Screening require secondary confirmation.
Presumptively positive samples at the Screening stage lead to additional hair extraction from the initial specimen for the Extraction stage. Here, drugs are extracted from hair at significantly lower concentrations than in other methods, such as urine or oral fluid, making hair drug screening the most challenging methodology.
Confirmation of any positive screening occurs through GC/MS, GC/MS/MS, or LC/MS/MS technologies. All presumptive positive samples undergo washing before confirmation if necessary. The complete process from Accessioning to Confirmation is scrutinized according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.
Advantages of hair drug testing:
