Hair examinations have become recognized as an effective method for identifying drug and alcohol consumption. Hair can provide an extended history of substance use by capturing biomarkers within the strands as they grow. When taken near the scalp, hair can reveal a detection timeframe of up to roughly three months for substances such as alcohol and drugs. Hair collection is straightforward, challenging to tamper with, and convenient to transport.
A sample measuring 1.5 inches, consisting of approximately 200 hair strands (equivalent to a #2 pencil's thickness) nearest the scalp, will yield 100mg of hair—ideal for screening and verification. For EtG, additional tests, or tests exceeding 10 panels, a sample of 150mg is preferred. We advise using a jeweler's scale for accurate specimen weight measurement. If the scalp hair isn't accessible, an equivalent portion of body hair may be gathered. When mentioning head hair, we refer specifically to scalp hair. Body hair encompasses all other hair categories (such as facial, axillary, etc.).
Process Overview
The core steps in the laboratory processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial entry of a sample into the laboratory's system, confirming that the sample was properly sealed and shipped, assigning it a random LAN (Laboratory Accessioning Number), and completing any missing information not supplied by an electronic chain of custody system.
Screening is a preliminary examination for the presence of drugs. Although Screening efficiently dismisses drug usage in most samples, a positive result must be verified to be admissible in legal contexts. All samples showing presumptive positivity in Screening mandate further confirmation.
Upon gaining a presumptive positive in the Screening phase, additional hair is extracted from the original specimen and groomed for Extraction. In this particular phase, drugs are separated from the hair at a notably lower concentration than other methods (such as urine or oral fluid), underscoring the intricate complexity of hair drug screening.
The verification of any positive screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation as necessary, all presumptively positive samples undergo washing. The comprehensive laboratory cycle from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair criteria and accreditation to ISO / IEC 17025 standards.
