Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. The hair captures a long-term record of alcohol and drug presence by embedding biomarkers within the fibers of the hair as it grows. When taken close to the scalp, it can show drug or alcohol use for as far back as three months. Hair is easy to obtain, has a low chance of tampering, and is straightforward to transport.
Collecting a 1.5-inch portion of around 200 hairs (similar in thickness to a #2 pencil) close to the scalp results in approximately 100mg of hair, which is the preferred amount for initial analysis and validation. For the EtG, additional studies, or anything exceeding 10 panels, 150mg of the sample is suggested. It is advisable to weigh the sample using a jeweler’s scale. If scalp hair is not accessible, an equivalent quantity of body hair can be used. When referring to head hair, it specifically means hair from the scalp. Conversely, body hair encompasses other types like facial or axillary.
Process Overview
The procedural flow for lab analysis of a drug test comprises Accessioning, Screening, Extraction, and Confirmation.
Accessioning constitutes the sample’s entry into the lab's database. This step consists of ensuring the sample’s proper sealing and shipment, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any missing data not captured by an electronic chain of custody.
Screening is an initial rapid assay for drug substances. While it serves as a cost-effective mechanism to negate drug usage in most samples, confirmed results are mandatory for courtroom presentation. Consequently, any samples that test positive initially need further confirmation.
With a preliminary positive in the Screening phase, additional hair is taken from the original collection and processed for Extraction. During this step, drugs are isolated from the hair at much more reduced concentrations than other methods, like urine or saliva, reflective of the complexity in executing hair drug testing.
Verification of any initial positive screening is pursued using GC/MS, GC/MS/MS, or LC/MS/MS technologies. Presumptive positive samples undergo washing before confirmation as per need. The entire lab method from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair certificate and ISO / IEC 17025 accreditation.
