Hair testing is regarded as an effective means for identifying drug and alcohol consumption. The hair retains markers from these substances within its strands, offering a comprehensive timeline. When sampled proximate to the scalp, hair enables detection of substances up to nearly 90 days. Collection of hair is straightforward, relatively tamper-resistant, and easy for shipping purposes.
A 1.5-inch sample consisting of 200 hair strands (around the thickness of a #2 pencil) nearest to the scalp achieves 100mg, which is the optimal sample size for analysis. In cases of EtG tests, extended panels, or tests exceeding 10 panels, a specimen amount of 150mg is advised. Measurement should be conducted using a jeweler’s scale. If scalp hair is not available, a comparable quantity of body hair can be used. When mentioning head hair, we mean scalp hair exclusively. Body hair pertains to other hair types (facial, axillary, etc.).
Process Overview
The laboratory processing of drug test samples consists of four pivotal steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails entering a sample into the lab's system. It involves ensuring the sample's packaging and transport were done securely, assigning a randomized LAN (Laboratory Accessioning Number), and filling in any missing data that is not included in an electronic chain of custody.
Screening involves conducting a preliminary evaluation for substance abuse. Although a cost-efficient method to exclude many samples from drug use, any positive result from the Screening phase must be confirmed for judicial acceptance. Samples tentatively positive during Screening necessitate additional Confirmation.
When a sample might test positive in the Screening phase, more hair is selected from the original batch for Extraction. In this step, substances are isolated from hair in concentrations significantly lesser than other testing types (e.g., urine or saliva). This unique aspect makes hair testing notably challenging.
Positive results from the Screening phase are confirmed through GC/MS, GC/MS/MS, or LC/MS/MS processes. All presumptive positives are cleaned prior to Confirmation as needed. The complete process from Accessioning to Confirmation adheres to both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.
