Hair assessments are increasingly recognized as an effective method for uncovering drug and alcohol consumption. Hair archives a prolonged history of alcohol and other substances by encapsulating biomarkers within the expanding hair fibers. Gathering hair near the scalp allows for an approximate 3-month period in which alcohol and other drugs can be unveiled. Hair collection is straightforward, relatively tamper-resistant, and convenient for shipping.
A length of 1.5 inches comprising roughly 200 hair strands (equivalent to a #2 pencil) nearest the scalp provides 100mg, which is deemed optimal for testing and validation. For EtG, supplementary tests, and/or analyses exceeding 10 panels, a 150mg sample is advised. It's suggested to use a jeweler’s scale for weighing the specimen. In the absence of scalp hair, a commensurate volume of body hair can be gathered. Referring specifically to head hair means scalp hair, whereas body hair includes all other types (e.g., facial, axillary).
Process Overview
The key stages in processing a drug test result in a laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails introducing a sample into the laboratory system, which involves verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing other required manual data entries if not facilitated by an electronic chain of custody system.
Screening provides a preliminary evaluation for substance use. While it's a cost-efficient way to dismiss drug presence in most samples, a positive finding needs affirmation before any legal admissibility. Presumptive positive samples in the Screening phase require further confirmation.
Should Screening indicate potential positivity, additional hair is extracted from the primary sample for Extraction. In this segment, drugs are meticulously extracted from hair at significantly lower concentrations than other methods (such as urine or saliva), rendering hair testing more challenging.
Confirmation for any positive outcome in Screening utilizes techniques like GC/MS, GC/MS/MS, or LC/MS/MS. All samples with presumptive positives are cleansed before confirmation as necessary. The comprehensive laboratory operation, from Accessioning to Confirmation, is scrutinized following both the CAP (College of American Pathologists) Hair criteria and ISO / IEC 17025 accreditation.
