The perception of hair testing has evolved into a robust mechanism for identifying drug and alcohol consumption. Hair retains a historical record of alcohol and drug intake by encasing biomarkers within the strands of the expanding hair. If gathered near the scalp, it can present nearly a three-month detection period for alcohol and drugs. Hair is easy to gather, relatively tough to tamper with, and straightforward to transport.
A segment of hair, measuring 1.5 inches and containing around 200 strands (approximately the diameter of a #2 pencil) near the scalp, equates to 100mg, which is ideal for screening and confirmation. For tests involving EtG, extra panels, or more than 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale to weigh the specimen. If scalp hair is not accessible, an equivalent quantity of body hair can be collected. "Head hair" refers exclusively to scalp hair, while "body hair" encompasses other types, including facial and axillary hair.
Process Overview
The laboratory assessment of a drug test result encompasses four fundamental stages: Accessioning, Screening, Extraction, and Confirmation.
Accessioning is the preliminary stage where a sample is integrated into the laboratory's system. This involves confirming the proper sealing and transportation of the sample, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entries not covered by an electronic chain of custody.
Screening is a preliminary assessment for drugs of abuse. Though Screening is a budget-friendly method to dismiss drug use in the majority of samples, any positive results must be verified for court admissibility. Samples with a positive screening require a follow-up confirmation.
In cases of positive results in Screening, more hair is retrieved from the initial sample for Extraction. During this phase, drugs are separated from hair at significantly reduced concentrations compared to other methods (such as urine or oral fluid), rendering hair drug screening the most challenging method.
GC/MS, GC/MS/MS, or LC/MS/MS technologies are employed for the Confirmation of any positive screening outcomes. Necessary washing of presumptive positive samples is conducted before confirmation. The laboratory process from Accessioning to Confirmation adheres to CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.
