Hair testing has evolved into a highly effective method for identifying drug and alcohol consumption. Hair offers a prolonged record of substance use by capturing biomarkers within the strands as they grow. When obtained near the scalp, hair can reveal a detection period of up to three months for various substances. It is straightforward to collect, somewhat tamper-resistant, and easy to transport.
A sample measuring 1.5 inches in length and consisting of approximately 200 hairs (comparable to the width of a #2 pencil) closest to the scalp yields around 100mg of hair, which is the optimal quantity for assessment. For EtG, supplementary tests, or tests beyond 10 panels, a 150mg specimen is advised. We suggest checking the specimen's weight using a jeweler’s scale. If there's no scalp hair, an equivalent body hair amount can be taken. When specifying head hair, we only mean scalp hair, while body hair encompasses other types (e.g., facial, axillary).
Process Overview
There are four primary stages in the lab processing of a drug test, which are Accessioning, Screening, Extraction, and Confirmation.
Accessioning starts with integrating a sample into a lab’s workflow. This phase includes confirming proper sealing and shipping of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data input not covered by an electronic chain of custody system.
Screening is an initial rapid assessment for drugs. Although it offers a cost-efficient way to eliminate drug use in most samples, a positive screen must be confirmed for legal admissibility. Any samples with presumptive positives in Screening need further confirmation.
Should a sample test presumptive positive during Screening, more hair is extracted from the initial sample for the Extraction process. This phase isolates drugs from hair concentrations significantly lower than those found in other methodologies, such as urine or oral fluid, making hair drug screening the most challenging procedure to execute.
Confirmation of a positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Samples testing presumptive positive are cleaned as necessary before confirmation. The complete lab workflow, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair criteria and is accredited to ISO / IEC 17025 standards.
