Hair testing is increasingly regarded as a valuable method for identifying drug and alcohol use. Hair offers an extensive historical record of substance use by embedding biomarkers in its strands as it grows. When samples are taken near the scalp, hair can provide a detection period of up to about three months for substances like alcohol and other drugs. The collection process for hair is straightforward, relatively resistant to tampering, and easy to transport.
A 1.5-inch hair sample consisting of approximately 200 strands (akin to the thickness of a #2 pencil) closest to the scalp will yield 100mg of hair, the optimal quantity for both screening and confirmation processes. For tests analyzing EtG, add-ons, or panels exceeding ten, a specimen of 150mg is advised. It's recommended to measure the sample using a jeweler's scale. In situations where scalp hair is not present, equivalent body hair may be used. References to head hair specifically denote scalp hair. All other forms, such as facial or axillary, are categorized as body hair.
Process Overview
The drug testing laboratory procedures are categorized into these four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning refers to the preliminary handling of a sample upon entry into a laboratory. This phase ensures the sample was securely sealed and appropriately shipped, assigns it a unique LAN (Laboratory Accessioning Number), and enters data as necessary, especially if not captured by an electronic chain of custody.
Screening is a preliminary evaluation for the presence of drugs. Though Screening is a cost-efficient approach for dismissing drug usage in most samples, a positive result in Screening requires confirmation to hold up in court. Any samples that test preliminary positive in Screening need a secondary confirmation step.
For samples testing positive in Screening, additional hair is extracted from the original specimen for the Extraction step. In this phase, drugs are separated from hair at lower concentrations than other testing methods (e.g., urine or oral fluid), thus making hair drug screening a more challenging methodology to execute.
Confirmation testing on any positive results from Screening is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all samples testing preliminary positive are cleansed as necessary. From Accessioning through Confirmation, the complete laboratory procedure is evaluated under the CAP (College of American Pathologists) Hair criteria and accredited according to ISO / IEC 17025 standards.
