Hair tests are increasingly recognized as an effective means for identifying drug and alcohol usage. Hair captures a prolonged record of drugs and alcohol by embedding biomarkers into the growing hair strand fibers. When taken near the scalp, a hair sample can offer nearly a 3-month detection range for alcohol and drugs. Hair is easy to collect, relatively hard to tamper with, and simple to transport.
A 1.5-inch sample, consisting of around 200 strands (roughly the diameter of a #2 pencil) from the scalp area will yield 100mg of hair, the ideal amount for screening and confirmation tests. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the sample is advised. It's advisable to weigh the sample on a jeweler’s scale. If scalp hair isn't available, an equal amount of body hair can be used. Head hair specifically refers to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).
Process Overview
The four central steps in processing a drug test in a lab include Accessioning, Screening, Extraction, and Confirmation.
Accessioning consists of the preliminary processing of a sample in a lab's system. This entails ensuring the sample was correctly sealed and transported, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entry not covered by an electronic chain of custody system.
Screening is about conducting an initial check for drugs. Although Screening is cost-efficient for eliminating drug use in the majority of samples, positive screens must be validated to be admissible legally. Samples with a presumptive positive in Screening need further Confirmation.
If a sample is presumptive positive during the Screening, additional hair is extracted from the original specimen and readied for Extraction. Here, drugs are isolated from hair at much lower concentrations than in other methods (such as urine or oral fluid), making hair drug screening the most challenging methodology.
Confirmation of any positive screen is executed via GC/MS, GC/MS/MS or LC/MS/MS. All presumptive positive samples are cleansed before confirmation as necessary. The full laboratory process from Accessioning to Confirmation undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 standards accreditation.
