Hair testing has emerged as an effective means for uncovering drug and alcohol consumption. The hair captures biomarkers within its growing strands, offering a prolonged view of substance use. When harvested near the scalp, hair can indicate consumption over a span of up to roughly three months. It's straightforward to collect, challenging to tamper with, and simple to transport.
A 1.5-inch section of roughly 200 hairs (approximately the size of a #2 pencil) from the scalp yields 100mg, which is optimal for both screening and confirmation. For EtG additions or tests exceeding 10 panels, 150mg of hair is preferred. We suggest using a jeweler’s scale for accuracy in weighing the sample. Should scalp hair be inaccessible, an equivalent mass of body hair is suitable. "Head hair" pertains exclusively to scalp hair, while "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The primary steps in processing the drug test at the laboratory include Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial processing where the sample enters the lab's system. This step ensures that the sample's seal and shipment were intact, assigns a Laboratory Accessioning Number (LAN) randomly, and completes any missing data not covered by an electronic custody chain system.
Screening provides an initial assessment for drug presence. While it's a cost-effective approach to evaluate most samples for drug usage, confirmed results are necessary for legal acceptance. Any samples testing positive at this stage require further confirmation.
If a Screening suggests drug presence, more hair is extracted from the original sample for further Examination. During this phase, drugs are extracted at notably lower concentrations than with other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug testing.
Confirmation of a positive result involves techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples undergo necessary pre-confirmation washing. Every step from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation and compliant with ISO / IEC 17025 standards.
