Hair assessments have emerged as an effective method for identifying substance and alcohol usage. Hair captures a prolonged timeline of substance exposure by embedding markers in the strands of growing hair. When cut near the scalp, hair can reveal drug and alcohol presence for up to roughly 90 days. It's easy to obtain, challenging to tamper with, and straightforward to transport.
A sample size of 1.5 inches, comprising around 200 hair strands closest to the scalp (comparable to a #2 pencil thickness), yields 100mg of hair, ideal for analysis and verification. For tests like EtG and those exceeding 10 panels, 150mg is advised. Measuring the sample on a jeweler’s scale is suggested. If head hair is lacking, an equivalent quantity of body hair may be used. Here, head hair signifies scalp hair, while body hair encompasses all other hair types (such as facial or axillary).
Process Summary
There are four primary phases in lab processing of a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.
Accessioning involves the initial integration of a sample into a lab's database. This step ensures the sample was properly sealed and shipped, assigns a unique LAN (Laboratory Accessioning Number), and handles any supplementary data input absent in an electronic custody chain system.
Screening is a preliminary assessment for substance misuse. It offers a cost-efficient method for dismissing drug use in most samples, though a positive outcome requires confirmation for legal validity. Samples that are tentatively positive during Screening need further verification.
If a sample shows potential positivity in Screening, additional hair is extracted from the original sample for the Extraction phase. This process retrieves drugs from hair at a significantly lower concentration than alternative methods (like urine or oral fluid), underscoring the complexity of hair drug screening.
Verification of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to verification, all tentatively positive samples undergo cleansing if necessary. Each stage from Accessioning to Verification is audited under the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.
