Seen as an effective measure for identifying drug and alcohol usage, hair testing offers an extended history of alcohol and drugs by capturing biomarkers within the fibers of the hair strand as it grows. A sample of hair collected near the scalp can provide an approximately three-month detection timeline for alcohol and drugs. Hair is easy to gather, relatively hard to tamper with, and convenient to deliver.
A sample measuring 1.5 inches with about 200 hair strands (similar in size to a #2 pencil) nearest the scalp gives 100mg of hair, the ideal amount for screening and validation. For EtG, add-ons, and/or tests exceeding 10 panels, 150mg of the specimen is advisable. It's recommended to weigh the specimen using a jeweler's scale. Should scalp hair not be attainable, an equivalent amount of body hair might be used. When mentioned, head hair specifically refers to scalp hair. Body hair indicates other hair types (e.g., facial, axillary, etc.).
Process Overview
The laboratory processing of a drug test result principally involves Accessioning, Screening, Extraction, and Confirmation.
Accessioning sets off with the initial processing of a sample within a laboratory's system. This step ensures that the sample is sealed and dispatched correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry not covered by an electronic chain of custody system.
Screening executes a preliminary fast check for substance abuse. While Screening economically rules out drug usage for most samples, a positive screen needs validation for court admissibility. Any samples that show presumptive positivity in Screening necessity secondary confirmation.
If a sample is presumptive positive in the Screening stage, more hair is taken from the initial specimen for Extraction preparation. During this phase, drugs are isolated from hair in much lower concentrations than other methods (e.g., urine or oral fluid), making hair drug screening the most challenging methodology to conduct.
GC/MS, GC/MS/MS, or LC/MS/MS conduct Confirmation of any positive Screening result. Before confirmation, all presumptively positive samples undergo necessary washing. The laboratory process from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.
