Hair analysis is increasingly recognized as a reliable method for identifying substance and alcohol consumption. As hair develops, it captures biomarkers within its fibers, offering a prolonged history of alcohol and drug use. Sampling hair near the scalp allows for a detection period of up to around three months for alcohol and drugs. The collection process is straightforward, relatively resistant to tampering, and convenient for shipping.
A strand length of 1.5 inches, comprising roughly 200 pieces of hair (equivalent to a #2 pencil), yields 100mg of hair, which is ideal for initial testing and subsequent confirmation. For EtG, additional assessments, or tests exceeding 10 panels, 150mg of hair is advisable. Using a jeweler's scale for weighing is suggested. Should scalp hair be unavailable, an equivalent quantity of body hair can be utilized. "Head hair" specifically denotes scalp hair, whereas "body hair" encompasses all other types (facial, axillary, etc.).
Process Overview
The key phases in the lab handling of a drug test result include Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the initial stage where a sample is entered into a lab's system, confirming proper sealing and delivery, assigning a random Laboratory Accessioning Number (LAN), and inputting any required data outside an electronic chain of custody framework.
Screening is a preliminary check for substance presence. Although Screening is a cost-efficient method for dismissing drug use in most cases, any positive findings must be confirmed to hold up in legal settings. Samples testing as presumptively positive during Screening necessitate further confirmation.
For samples showing presumed positive results in Screening, additional hair from the original sample undergoes preparation for Extraction. Here, drugs are retrieved from hair at significantly lower levels than other methods (e.g., urine or oral fluids), making hair drug testing a complex process.
Confirmation of any positive results from screening is performed using GC/MS, GC/MS/MS or LC/MS/MS techniques. Samples with presumed positive findings are washed before confirmation as necessary. The complete lab process, from Accessioning through Confirmation, is examined under the CAP (College of American Pathologists) Hair designation and in accordance with ISO / IEC 17025 accreditation standards.
