Hair tests are regarded as an effective method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drugs by incorporating biomarkers into the hair strand as it grows. When hair is collected near the scalp, it can offer approximately a 3-month observation period for detecting alcohol and drugs. Hair is easy to collect, challenging to tamper with, and simple to transport.
A 1.5-inch sample comprising around 200 hair strands (comparable to a #2 pencil) taken closest to the scalp provides 100mg of hair, the preferred amount for both screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, it's advisable to have 150mg of the sample. We advise weighing the sample using a jeweler’s scale. If scalp hair isn't available, a similar amount of body hair may be used instead. When mentioning head hair, we mean scalp hair exclusively. Body hair signifies all other hair categories (facial, axillary, etc.).
Process Overview
The core steps in the lab processing of a drug test result are Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the initial logging of a sample into the lab's system. This process checks if the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any data entry not covered by an electronic chain of custody system.
Screening conducts a preliminary assessment for substances of abuse. Though Screening serves as a cost-efficient means to dismiss drug presence in most samples, any positive screening must be verified to be valid in a legal context. All samples that are presumed positive during Screening necessitate secondary confirmation.
Should a sample test presumptively positive in the Screening phase, additional hair is extracted from the initial sample and readied for Extraction. During Extraction, drugs are retrieved from hair at lower concentrations than in other methods (e.g., urine or oral fluid), contributing to the complexity of hair drug testing.
Positive screening results undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed before confirmation if necessary. Every aspect of the lab processing, from Accessioning to Confirmation, is audited under both the CAP (College of American Pathologists) Hair standard and the ISO / IEC 17025 accreditation.
