Hair testing is increasingly recognized as an effective means for identifying drug and alcohol use. Hair captures a comprehensive historical record of alcohol and drug consumption by incorporating biomarkers within the strands of growing hair. When sourced near the scalp, hair analysis can reveal a detection span of up to roughly 3 months for alcohol and other substances. The collection process is straightforward, somewhat resistant to tampering, and convenient to transport.
A sample of 1.5 inches, containing about 200 strands of hair (comparable in size to a #2 pencil) from the scalp region, yields 100mg of hair, which is the ideal quantity for both screening and confirmatory purposes. For tests involving EtG, additional components, and/or over 10 panels, 150mg of hair is advised. It's suggested to weigh the sample on a jeweler's scale. If scalp hair is not available, an equivalent quantity of body hair can be used. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other hair types (like facial or axillary hair).
Process Overview
The laboratory processing of a drug test result comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning includes the initial integration of a sample into the lab's system. This step verifies the proper sealing and shipping of the sample, assigns a random Laboratory Accessioning Number (LAN), and completes any remaining data entry absent from an electronic chain of custody system.
Screening serves as a preliminary swift assessment for substances of abuse. Although Screening is an economical method to rule out substance usage for most samples, confirmation is necessary for any positive-screened samples to ensure their admissibility in court. Such samples presumed positive in Screening necessitate a subsequent confirmation.
For samples marked presumptively positive during Screening, the next step involves taking additional hair from the primary sample for Extraction. Here, drugs are extracted from hair at much lower concentrations compared to other methods (e.g., urine or oral fluid), underscoring the complexity of hair drug testing.
Confirmation of a positive screening outcome is performed using techniques like GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, any presumptively positive samples undergo washing as needed. The complete laboratory process from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although often termed "hair follicle tests," the analysis focuses on the hair strand rather than the follicle beneath the scalp.
Why does hair follicle testing outshine urine methods in Hartman, CO? The answer lies in its superior accuracy and reliability.
