Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair testing is increasingly regarded as a potent method for identifying drug and alcohol usage. Hair captures a historical record of these substances by encasing biomarkers within the strands of hair as they grow. When collected close to the scalp, this can extend the detection window for drugs and alcohol to roughly 3 months. Hair is straightforward to collect, challenging to tamper with, and easy to transport.
A sample size of 1.5 inches composed of around 200 hair strands (approximately matching the girth of a #2 pencil) nearest to the scalp equates to 100mg, which is the preferred quantity for screening and verification. For EtG, supplementary assays, and/or tests exceeding 10 panels, a 150mg specimen is advised. It's best to weigh the specimen using a jeweler’s scale. Should scalp hair be unattainable, a similar amount of body hair can be utilized. The term "head hair" specifically refers to scalp hair, while "body hair" encompasses all other hair types (e.g., facial, axillary).
Process Overview
Drug test result processing in the lab involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails the preliminary handling of a sample within a lab's framework. This step verifies proper sealing and shipment of the sample, allocates a unique LAN (Laboratory Accessioning Number), and finishes any remaining data input absent from an electronic custody system.
Screening consists of an expeditious preliminary drug check. Despite being cost-effective for ruling drug use out in most samples, a positive screen must be confirmed for it to be admissible in a legal context. Samples returning presumptive positive results require a secondary confirmation.
Presumptive positive samples from the Screening stage undergo further hair extraction from the original sample for Extraction preparation. This stage involves extracting drugs from hair at lower concentrations than possible with methodologies such as urine or oral fluids, which is why hair drug testing is notably challenging.
Confirmation of positive screening findings is performed using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples are cleaned before confirmation as necessary. From Accessioning to Confirmation, the full laboratory process is scrutinized in compliance with both the CAP (College of American Pathologists) Hair guidelines and ISO/IEC 17025 accreditation standards.
Advantages of hair drug testing:
Limitations:
Note: Although known as "hair follicle tests", this testing examines the hair strand and not the follicle under the skin.
