Urine| Hair Follicle | Oral Fluid | Blood | ETG
Hair assessments have emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged history of substances by embedding biomarkers within the strands. When taken near the scalp, hair offers up to an approximate three-month detection span for alcohol and drugs. It's easy to gather, reasonably hard to tamper with, and convenient to send.
A 1.5-inch length comprising roughly 200 hair strands (similar to a #2 pencil in thickness) near the scalp provides 100mg, the perfect volume for analysis. For EtG, extra tests, and/or panels exceeding 10, 150mg is advised. We suggest measuring the specimen on a jeweler's balance. If scalp hair isn't present, an equivalent portion of body hair can be taken. "Head hair" refers specifically to scalp hair, whereas "body hair" encompasses all others (such as facial or axillary hair).
Process Overview
The process entailing four primary phases in lab analysis of drug test results includes Accessioning, Screening, Extraction, and Confirmation.
Accessioning entails introducing a sample into the lab’s framework. This step verifies proper sealing and shipment of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data tasks not fulfilled by an electronic chain of custody.
Screening gives a preliminary examination for substance use. While cost-effective for clearing most samples of drug use, any positive outcome during Screening demands additional verification for court validity. Presumptively positive samples necessitate a follow-up confirmation.
When Screening suggests a positive result, more hair is derived from the initial specimen for Extraction. Drugs are retrieved from hair at a reduced concentration compared to alternative techniques (e.g., urine or saliva), highlighting the challenges in hair drug analysis.
Confirming a positive screen involves methodologies like GC/MS, GC/MS/MS, or LC/MS/MS. All samples flagged as presumptive positives are cleansed before confirmation as necessary. The entire process, from Accessioning to Confirmation, undergoes scrutiny under the CAP (College of American Pathologists) Hair designation alongside ISO / IEC 17025 accreditation.
