Seen as a robust resource, hair testing effectively detects drug and alcohol consumption. Hair strands capture biomarkers within the fibers, yielding a comprehensive history of alcohol and drug usage. When harvested near the scalp, hair offers a detection window that spans roughly 90 days for alcohol and drugs. Hair is uncomplicated to gather, relatively resistant to tampering, and straightforward to send.
Collecting a 1.5-inch segment of around 200 strands of hair nearest the scalp results in 100mg of hair, which is ideal for both screening and confirmation. For EtG, additional tests, or those exceeding 10 panels, 150mg of the sample is recommended. It is advised to utilize a jeweler's scale to weigh the sample. If scalp hair is absent, an equal quantity of body hair can be gathered. "Head hair" pertains solely to scalp hair, whereas "body hair" encompasses all other types (such as facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary integration of a sample into a laboratory's framework. This step includes confirming that the sample was correctly sealed and sent, assigning a unique LAN (Laboratory Accessioning Number), and performing any supplementary data entry that an electronic chain of custody system doesn't cover.
Screening serves as an initial, rapid assessment for drug misuse. While cost-effective, a positive screening outcome must be verified to be valid in a court of law. Samples that test presumptive positive during Screening need follow-up confirmation.
Presumptive positives during Screening prompt additional hair to be taken from the primary sample for the Extraction process. During Extraction, drugs are isolated from hair at a considerably lower concentration than other techniques (e.g., urine or oral fluid), rendering hair drug screening as the most complex methodology.
Positive results from screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before Confirmation as deemed necessary. The complete laboratory sequence from Accessioning through to Confirmation complies with CAP (College of American Pathologists) Hair designations and ISO / IEC 17025 accreditation.
