Hair testing is recognized as an effective means for identifying drug and alcohol use. It offers a prolonged history of substance intake by trapping biomarkers within the fibers of the hair strand as it grows. When hair is collected near the scalp, it provides up to about a 3-month span for detecting alcohol and other substances. Hair collection is straightforward, resistant to tampering, and simple to transport.
A sample that is 1.5 inches long and consists of roughly 200 hair strands (approximately the diameter of a #2 pencil) fetched closest to the scalp will yield 100mg, which is optimal for both screening and confirmation. For EtG, additional tests or screenings beyond 10 panels, 150mg of the sample is advised. We suggest weighing the sample on a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair can be used. In mentioning head hair, we mean scalp hair exclusively. Body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the first phase in which a sample is processed into the lab’s system. This step verifies that the sample is appropriately sealed and shipped, assigns a random LAN (Laboratory Accessioning Number), and includes any additional data entry not already accomplished by an electronic chain of custody system.
Screening acts as an initial, swift assessment for substances of abuse. Screening is an economical method to often negate drug usage in most samples; however, a positive result requires confirmation to be legally valid. Presumptively positive specimens during Screening must undergo secondary confirmation.
Should a sample be presumptively positive in the Screening phase, further hair from the original specimen is used for the Extraction step. In this process, drugs are retrieved from hair at a much lower concentration than other methods (like urine or oral fluid), which is why hair drug testing poses the greatest challenge.
Confirmation of any positive results from screening is conducted via GC/MS, GC/MS/MS or LC/MS/MS. Any presumptive positive samples are washed before confirmation if necessary. The complete lab process from Accessioning to Confirmation is examined under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
