Hair analysis has gained recognition as a robust method for the identification of drug and alcohol consumption. Hair retains a long-term record of alcohol and other substances by capturing markers in the structure of the growing hair shaft. When sourced near the scalp, hair can offer a detection period of roughly 3 months for alcohol and other substances. Hair is straightforward to collect, relatively challenging to tamper with, and convenient to transport.
A sample sized at 1.5 inches consisting of around 200 hair fibers (approximately as thick as a #2 pencil) nearest to the scalp will yield 100mg of hair, the perfect sample for both screening and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of the sample is advised. We suggest measuring the specimen on a jeweler’s scale. If scalp hair is unattainable, a comparable amount of body hair can be gathered. When mentioning head hair, we are specifically talking about scalp hair only. Body hair denotes all other types (such as facial, axillary, etc.).
Process Overview
The process of analyzing a drug test involves four key stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the laboratory’s system. This step involves confirming that the sample was correctly sealed and transported, assigning a distinctive LAN (Laboratory Accessioning Number), and finishing any further data entry not accounted for by an electronic chain of custody system.
Screening refers to a preliminary rapid assessment for drug presence. While Screening is a budget-friendly method to exclude drug use in the majority of samples, a positive result needs validation to be considered valid in legal settings. Samples showing presumptive positivity in Screening require a subsequent confirmation.
For presumptively positive samples in the Screening stage, additional hair is retrieved from the original sample for Extraction. In this phase, the extraction of drugs from hair is conducted at a much finer concentration level than in other approaches (such as urine or oral fluids), which accounts for the high complexity of hair drug work.
Confirmation of any positive screenings is performed through GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positivity undergo washing before verification as necessary. The entire lab procedure from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standards and the accreditation to ISO / IEC 17025 norms.
