Hair testing is recognized as an effective method for identifying drug and alcohol consumption. By capturing biomarkers within the fibers of the hair strand as it grows, hair offers a comprehensive history of alcohol and drug use over an extended period. Sampling hair close to the scalp can reveal a detection window for alcohol and other substances that extends up to nearly three months. The collection process for hair is straightforward, somewhat tamper-resistant, and convenient for shipping.
A sample of hair measuring 1.5 inches with approximately 200 strands (about the thickness of a #2 pencil) taken from near the scalp provides a 100mg quantity, which is optimal for both screening and validation. For EtG, add-ons, and/or analyses exceeding 10 panels, a specimen amount of 150mg is advised. A jeweler’s scale should be used to verify the sample’s weight. In cases where scalp hair cannot be obtained, an equivalent quantity of body hair is an alternative. Head hair strictly refers to scalp hair, whereas body hair encompasses all other types such as facial and axillary hair.
Process Overview
The four primary stages in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.
Accessioning pertains to the initial administration of a sample within a laboratory’s framework. This stage ensures the sample is correctly sealed and dispatched, assigns a LAN (Laboratory Accessioning Number) at random, and completes any missing data entry not covered by an electronic chain of custody tool.
Screening acts as a preliminary evaluation for detecting substances of abuse. Although a Screening is a budget-friendly approach to dismissing drug use in the majority of cases, any positive result requires confirmation to be accepted legally. Samples with presumptive positive results in Screening necessitate a secondary confirmation.
Should the Screening stage indicate a presumptive positive, additional hair is drawn from the initial sample for the Extraction phase. In Extraction, substances are drawn out from hair at a significantly lower concentration compared to other methods (such as urine or oral fluid), which is a reason hair drug testing is particularly challenging to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS techniques confirm any positive results detected in screening. All samples considered presumptively positive undergo necessary washing before confirmation. This entire laboratory process, from Accessioning through to Confirmation, is conducted under the scrutiny of CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
