Acknowledged as an effective method, hair testing is highly effective for uncovering substance and alcohol intake. Hair retains a prolonged history of substance consumption by embedding biomarkers within the fibers of its strands as they grow. When cut near the scalp, hair can reveal substance use data from up to three months. Collecting hair is straightforward, hard to tamper with, and simple to transport.
A lock of hair measuring 1.5 inches, featuring around 200 strands (approximately the girth of a #2 pencil) closest to the scalp, yields 100mg—a prime sample amount for both screening and verification. For EtG, supplemental tests, or examinations exceeding 10 panels, a 150mg sample is advised. It's wise to measure the sample using a jeweler's scale. If scalp hair cannot be sourced, an equivalent amount of body hair can be utilized. By head hair, we specifically denote scalp hair; body hair refers to any other types like facial or axillary.
Process Overview
The drug testing process within a laboratory encompasses four crucial stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning signifies the preliminary handling of a sample into the laboratory’s database. This involves verifying proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and concluding any supplementary data input absent from an electronic chain of custody.
Screening is initiated to swiftly detect drug misuse. Although Screening is an economical approach to dismiss drug usage for the majority, confirming a positive screen is necessary for legal admissibility. Samples with presumptive positivity during Screening require additional confirmation.
For samples indicated as presumptively positive in Screening, more hair is extracted from the initial sample for preparing Extraction. Here, drug extraction from hair occurs at lower concentrations than other methods (such as urine or oral fluid), rendering hair testing more complex.
Confirmation of a positive screening outcome employs GC/MS, GC/MS/MS, or LC/MS/MS techniques. Samples flagged for presumptive positivity undergo washing before confirmation if required. From Accessioning through to Confirmation, the entire laboratory procedure complies with both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 standards.
