Hair testing stands out as a robust method for identifying drug and alcohol usage. By embedding biomarkers within the hair fiber, hair serves as an extended record of substance intake, capturing data as the strand grows. When sampled near the scalp, it can offer up to a 90-day detection period for alcohol and drugs. Collection is straightforward, tampering is relatively tough, and shipping is uncomplicated.
A sample measuring 1.5 inches with roughly 200 hair strands (comparable to a #2 pencil thickness) near the scalp yields 100mg, ideal for testing and verification. For EtG, additional tests, or those exceeding 10 panels, acquiring 150mg of the sample is preferable. We advise using a jeweler’s scale to measure the specimen. If scalp hair is missing, a comparable quantity of body hair is a suitable alternative. References to head hair denote scalp hair, while body hair includes all other types (facial, underarm, etc.).
Process Overview
The primary stages in processing a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning covers the initial integration of a sample into the laboratory workflow. This comprises ensuring the sample was correctly sealed and sent, assigning an anonymous LAN (Laboratory Accessioning Number), and handling any outstanding data entry absent from an electronic chain of custody.
Screening performs a preliminary rapid assessment for banned substances. While efficient for dismissing drug use in most samples, a positive result necessitates confirmation to be legally acceptable. Presumptive positive findings in Screening mandate secondary verification.
In cases of presumptive positive results in the Screening, additional hair is collected from the initial sample for Extraction. This phase retrieves drugs from hair at a significantly lower level than other techniques (like urine or oral fluid), underlining why hair drug testing poses the greatest challenge.
Confirmation of positive results is conducted via GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive specimens undergo washing prior to confirmation, if needed. The whole procedure from Accessioning to Confirmation is evaluated according to both CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025.
