Considered a potent instrument in identifying substance use, hair testing detects drugs and alcohol through biomarkers encased in hair fibers. When cut near the scalp, it provides an approximate 90-day look-back period for detecting substance use. Hair collection is straightforward, challenging to falsify, and convenient for shipping.
A 1.5-inch section containing roughly 200 hair strands (comparable to a #2 pencil) near the scalp equates to 100mg of hair, which is ideal for both screening and confirmation. For expanded panels or EtG tests, 150mg is advised. Using a jeweler's scale is recommended for weighing the sample. If scalp hair is not available, an equal quantity of body hair can be used. By "head hair", we refer specifically to scalp hair, while "body hair" denotes all other types (facial, axillary, etc.).
Process Overview
The principal steps in processing drug test results in a lab are Accessioning, Screening, Extraction, and Confirmation.
Accessioning engages in the initial sample integration into the lab system, ensuring it was correctly sealed and transported, assigning a distinct LAN (Laboratory Accessioning Number), and performing any extra data entry not covered by an electronic chain of custody.
Screening is a preliminary assessment for substance abuse. Although cost-efficient for dismissing drug usage in most samples, a positive Screening must be confirmed to be court-admissible. Samples with presumptive positive results in Screening require secondary confirmation.
Should a sample be presumptive positive during Screening, additional hair is extracted from the original sample for the Extraction phase. Here, drugs are drawn from the hair at a significantly lower concentration than alternative techniques (e.g., urine or oral fluid), underlining the complexity of hair drug screening.
Confirmation of any positive Screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation as required. The laboratory process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair designation alongside accreditation to ISO / IEC 17025 standards.
