Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair testing is recognized as a robust method for detecting drug and alcohol consumption. The fibers in the hair strand capture biomarkers, offering a historical record of substance use over an extended period. When taken from near the scalp, hair reveals up to a 3-month window for alcohol and drug detection. It's easy to collect, relatively tamper-resistant, and simple to transport.
A sample of 1.5 inches, roughly 200 hair strands (similar in size to a #2 pencil), taken close to the scalp provides 100mg, ideal for testing and confirmation. For EtG, add-ons, or tests beyond 10 panels, around 150mg is advised. A jeweler's scale is suggested for weighing the sample. In the absence of scalp hair, an equivalent volume of body hair can be used. "Head hair" refers solely to scalp hair, while "body hair" includes other types (facial, axillary, etc.).
Process Overview
The primary stages in the lab processing of a drug test are Accessioning, Screening, Extraction, and Confirmation.
Accessioning is where a sample is first entered into the lab system. This stage confirms the sample was correctly sealed and sent, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data not captured by an electronic chain of custody system.
Screening offers an initial, quick assessment for drug presence. While cost-effective, a positive result from Screening needs confirmation to be valid in court. Any samples that test as presumptively positive require further confirmation.
Should a sample test positive during Screening, more hair is taken from the original specimen for Extraction. Drugs are extracted from hair at a significantly lower concentration than other methods (e.g., urine or oral fluid), making hair drug screening particularly challenging to execute.
Confirmation of positive screenings is done using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positives undergo washing before the confirmation process as necessary. The entire lab procedure, from Accessioning to Confirmation, is subject to review under CAP (College of American Pathologists) Hair designation along with accreditation to ISO / IEC 17025 standards.
