Hair analysis has gained recognition as a strong method for detecting drug and alcohol use. Hair offers an extended history of alcohol and other drugs by embedding biomarkers in the strands of the hair as it grows. If taken close to the scalp, hair can offer a detection timeframe of up to roughly three months for alcohol and drugs. It is easy to gather, fairly resistant to tampering, and simple to transport.
A sample of 1.5 inches, consisting of approximately 200 hair strands (comparable to a #2 pencil in size) near the scalp provides 100mg of hair, which is the optimal quantity for tests and confirmations. For EtG, additional testing, or screens exceeding 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale for measuring the sample. If scalp hair is not available, a comparable amount of body hair can be used. In terms of head hair, we specifically mean scalp hair. Body hair includes all other hair types (like facial and axillary).
Process Overview
The core procedures in laboratory drug test result processing consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the initial handling of a sample into the lab’s system. This process ensures that the sample was properly sealed and shipped, assigns a LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody.
Screening offers an initial rapid drug abuse check. While economical for negating drug use in most samples, a positive screening outcome requires confirmation to be viable in judicial settings. Samples with presumptively positive results necessitate further confirmation.
If screening results in a presumptive positive, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are sourced from hair at much lower levels compared to other methods (like urine or saliva), making hair drug screening the most complex procedure to implement.
Any positive screening findings are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, presumptive positive samples are cleansed as needed. The full lab process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 standards.
