Hair analysis is increasingly regarded as an influential method for identifying drug and alcohol consumption. The hair acts as a record for drugs and alcohol over time by capturing biomarkers within the strands as they develop. When obtained near the scalp, hair can reveal a detection span of up to about three months for drugs and alcohol. Hair collection is easy, relatively hard to alter, and straightforward to transport.
A sample of 1.5 inches consisting of around 200 hairs (approximately akin to a #2 pencil) closest to the scalp weighs 100mg, considered the optimal amount for both screening and confirmation. For EtG, additional tests, and/or examinations exceeding 10 panels, 150mg of hair is advised. It's suggested to measure the sample using a jeweler's scale. If hair from the scalp is not accessible, a comparable quantity of body hair can be obtained. When we talk about head hair, we are specifically referring to scalp hair. Body hair encompasses all other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test is divided into four key steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial incorporation of a specimen into a lab's system. This step ensures that the sample is correctly sealed and transported, assigns an arbitrary LAN (Laboratory Accessioning Number), and addresses any supplementary data input not covered by an electronic chain of custody process.
Screening is a preliminary rapid assessment for substances of abuse. Although Screening is an economical way to eliminate drug usage across numerous samples, a positive result must be validated for it to be considered applicable in legal settings. All samples that are tentatively positive during Screening necessitate further confirmation.
Upon a presumptive positive result in Screening, additional hair is removed from the initial sample for Extraction. During Extraction, the drugs are removed from hair at significantly lower concentrations compared to alternative methods (e.g., urine or oral fluid), making hair drug analysis one of the most complex techniques to conduct.
Any positive result from the screening is then confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptively positive samples undergo a thorough wash prior to confirmation if required. The comprehensive laboratory procedure, ranging from Accessioning to Confirmation, complies with both the CAP (College of American Pathologists) Hair criteria and ISO/IEC 17025 accreditation standards.
