Hair testing is recognized as a robust method for identifying drug and alcohol use. This method captures a prolonged record of substance intake by embedding biomarkers within the strands of hair as they grow. Testing hair collected near the scalp offers a detection span of up to three months for various substances. Hair collection is straightforward, relatively tamper-resistant, and easily transported.
Obtaining a 1.5-inch segment consisting of roughly 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp yields 100mg of hair, which is optimal for both screening and confirmation stages. For tests that include EtG, add-ons, and those exceeding 10 panels, 150mg of hair is advised. It is best to measure the sample using a jeweler’s scale. If scalp hair can't be acquired, a similar volume of body hair can be used. When discussing head hair, this specifically indicates scalp hair. Body hair encompasses all other types such as facial and axillary hair.
Process Overview
Laboratory processing for drug tests includes the steps of Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the initial processing and integration of a sample into a lab's systems. This step ensures proper sealing and shipping, assigns a random LAN (Laboratory Accessioning Number), and finalizes any additional data input absent from the electronic chain of custody.
Screening initiates a quick assessment for drug presence. Although economical for ruling out substance use in most samples, any positive results in Screening must undergo confirmation to be court-admissible. Samples showing presumptive positivity necessitate further confirmation.
Samples showing presumptive positivity in the Screening phase undergo Extraction, requiring more hair from the primary specimen. Here, drugs are extracted from hair in much lower concentrations compared to urine or oral fluid methods, making hair testing the most complex method to execute.
For validating any positive screening outcomes, GC/MS, GC/MS/MS, or LC/MS/MS methods are used. Presumptively positive samples receive washing prior to confirmation if needed. The full laboratory sequence, from Accessioning through Confirmation, adheres to both CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
