Utilizing hair testing has emerged as an effective method to identify the consumption of drugs and alcohol. Hair serves as a long-lasting record of alcohol and drug use by capturing biomarkers within the fibers of the growing hair strand. When sourced near the scalp, hair can offer a detection period of up to roughly three months for alcohol and drugs. Hair collection is straightforward, relatively hard to tamper with, and simple to transport.
A 1.5-inch section consisting of approximately 200 hair strands (about the thickness of a #2 pencil) nearest to the scalp will yield 100mg of hair, the optimal sample for screening and validation. For EtG, additional tests, and/or evaluations exceeding 10 panels, 150mg of hair is suggested. It's advisable to measure the sample with a jeweler's scale. Should scalp hair be inaccessible, a comparable quantity of body hair can be gathered. When discussing head hair, it pertains solely to scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The key phases involved in laboratory handling of a drug test outcome consist of Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary processing of a sample into a laboratory’s system. This encompasses confirming that the sample was properly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and finalizing any additional data entry not supplied by an electronic chain of custody system.
Screening includes a preliminary swift examination for drugs of misuse. Although Screening offers a budget-friendly means to eliminate drug involvement in the bulk of samples, a positive screening must be corroborated to be permissible in legal proceedings. Any samples presenting a presumptive positive in Screening necessitate a secondary confirmation.
Should a sample demonstrate a presumptive positive in the Screening phase, more hair is extracted from the original specimen and prepared for Extraction. During this phase, drugs are drawn from hair at significantly lower concentrations than with other methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.
Verification of any positive screening result is executed through GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples undergo washing pre-confirmation as needed. The complete laboratory operation from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and accreditation per ISO / IEC 17025 criteria.
