Hair testing has become recognized as an effective tool for identifying drug and alcohol consumption. Hair offers a long-term record of these substances by capturing biomarkers within the fibers of the hair as it grows. When taken near the scalp, hair can offer a detection period of up to about 3 months for alcohol and other drugs. Hair collection is straightforward, relatively hard to tamper with, and uncomplicated to transport.
A 1.5-inch sample of roughly 200 hair strands (similar in size to a #2 pencil) nearest to the scalp will yield 100mg, the preferred sample for testing and confirmation. For EtG, additional tests, and tests beyond 10 panels, 150mg of the hair sample is advised. It's best to weigh the sample using a jeweler's scale. If scalp hair is unavailable, an equivalent quantity of body hair can be collected. Head hair specifically refers to scalp hair. Body hair includes all other types (like facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result encompasses four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the preliminary processing of a sample into the lab's system. This step includes ensuring the sample was sealed and shipped correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any required data entry not covered by an electronic chain of custody system.
Screening offers an initial rapid assessment for drug abuse. While Screening is a budget-friendly method to dismiss drug usage for most samples, a positive result requires confirmation for it to be legally acceptable. Samples that show a presumptive positive during Screening need secondary verification.
If screening indicates a sample may be positive, more hair from the original specimen is prepared for Extraction. In this stage, drugs are extracted from hair at a lower concentration compared to other methods (like urine or oral fluid), which is why hair drug screening remains the most challenging methodology.
Confirmation of a positive screening outcome is accomplished using GC/MS, GC/MS/MS or LC/MS/MS. All samples with a presumptive positive must be washed before confirmation if necessary. The complete laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
