Hair testing has emerged as an effective measure for identifying drug and alcohol consumption. By capturing biomarkers within the strands of growing hair, it provides a comprehensive history of substance intake. When sourced close to the scalp, hair offers an approximately 3-month detection window for alcohol and substances. Collecting hair is straightforward, fairly tricky to tamper with, and convenient to transport.
A 1.5-inch segment of roughly 200 hair strands (about the size of a #2 pencil) near the scalp yields 100mg, which is the ideal sample size for both screening and confirmation. For EtG, add-ons, or tests over 10 panels, a 150mg specimen is advised. Using a jeweler’s scale to weigh the specimen is recommended. If scalp hair can’t be acquired, a similar quantity of body hair may be utilized. When we mention head hair, we specifically mean scalp hair. Body hair denotes all other hair types (facial, axillary, etc.).
Process Overview
There are four primary steps in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.
In Accessioning, a sample is initially processed into a lab’s system. This step ensures the sample was sealed and sent correctly, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry absent from an electronic chain of custody system.
Screening is a rapid preliminary assessment for drugs of abuse. Although Screening is a cost-efficient method to rule out drug usage for most samples, a positive screen requires confirmation in order to be court-admissible. Any samples with presumptively positive results during Screening need further confirmation.
If a sample is presumptively positive during Screening, more hair is extracted from the main specimen for Extraction preparation. At this stage, drugs are removed from hair at much lower concentrations than other methods (ex. urine or oral fluid), making hair drug screening the most challenging methodology to execute.
Confirmation of any positive Screening result is conducted via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are washed before confirmation if necessary. The entire lab process from Accessioning to Confirmation is subjected to review under both the CAP (College of American Pathologists) Hair designation and the ISO / IEC 17025 accreditation standards.
