Hair testing is increasingly recognized as an effective method to detect drug and alcohol use. It reveals a long-term history by capturing biomarkers within the fibers of the hair as it grows. When collected near the scalp, it can indicate substance use over a period of around three months. The hair sample collection is straightforward, challenging to tamper with, and convenient to transport.
A standard sample size of 1.5 inches, consisting of approximately 200 strands near the scalp, equates to 100mg of hair, which is ideal for both screening and detailed confirmation. For extended tests like EtG, special add-ons, or tests exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale is recommended for accurate weighing. If the scalp hair isn't available, an equivalent amount of body hair can be gathered. When we mention head hair, it specifically refers to scalp hair, while body hair encompasses all other forms (such as facial or axillary).
Process Overview
The laboratory drug testing procedure comprises four essential steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails integrating the sample into the lab's system, which includes confirming proper sealing and shipping, assigning a Laboratory Accessioning Number (LAN), and fulfilling any additional data requirements not captured by the electronic chain of custody system.
Screening provides a preliminary check for drug use. It is a cost-efficient method to exclude drug presence in most samples, but any detection requires further confirmation for legal validity. Samples suspected of drug positivity in Screening need subsequent verification.
In cases of suspected positivity during Screening, additional hair is extracted from the original sample for the Extraction step. Here, drugs are isolated from the hair at significantly lower concentrations than other testing methods like urine or saliva, highlighting hair drug testing as a challenging technique.
Upon a positive Screening indication, Confirmation is executed using methods such as GC/MS, GC/MS/MS, or LC/MS/MS. Samples showing presumptive positivity undergo a necessary washing before Confirmation. Every step from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.
