Recognized for their efficacy, hair tests are a robust method for identifying drug and alcohol consumption. Hair captures a comprehensive timeline of substance intake by embedding biomarkers within the growing hair strands. When taken from near the scalp, hair can reveal alcohol and drug usage over an estimated three-month period. It is easy to gather, poses challenges for tampering, and is straightforward to transport.
A sample measuring 1.5 inches, containing approximately 200 hair strands (akin to the girth of a #2 pencil) nearest to the scalp, yields about 100mg of hair—ideal for screening and confirming presence. For EtG, additional tests, and/or more than 10 panels, a 150mg sample is advisable. To ensure proper measurement, using a jeweler’s scale is recommended. If scalp hair cannot be obtained, equivalent body hair may be used. "Head hair" specifically denotes scalp hair. "Body hair" includes all other types (facial, axillary, etc.).
Process Overview
The laboratory process for drug test results consists of four main stages: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, a sample is introduced into the laboratory's system. The process ensures the sample is sealed and sent correctly, assigns a LAN (Laboratory Accessioning Number) randomly, and completes any needed data entry absent in an electronic chain of custody.
Screening serves as a preliminary, swift evaluation for drug markers. It efficiently rules out drug use in most samples, but a confirmed test is required to establish validity for legal proceedings. Any samples showing positive results during Screening necessitate subsequent confirmation.
Should Screening suggest a positive result, additional hair is drawn from the sample for Extraction. Drugs are isolated from the hair at concentrations significantly lower than in other test types (e.g., urine or oral fluid), underlining the complexity of hair drug analysis.
Positive findings upon Screening proceed to Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Before confirmation, samples found presumptively positive are cleaned as required. The comprehensive lab process from Accessioning through Confirmation adheres to the CAP (College of American Pathologists) Hair guidelines and abides by ISO / IEC 17025 standards.
