Hair analysis is recognized as an effective method for tracking the use of drugs and alcohol. The strands of hair capture markers over time within their growing fibers, offering a prolonged timeline of substance use. When hair is taken near the scalp, it can reveal drug and alcohol usage for as long as three months. Gathering hair is straightforward, tampering with it is relatively challenging, and it is convenient for shipping.
A sample consisting of 1.5 inches of around 200 strands (similar in size to a #2 pencil) near the scalp provides 100mg, which is the preferred amount for testing and verification. For examinations like EtG, additional tests, or tests beyond 10 panels, it is advised to use 150mg of hair. Using a jeweler’s balance for weighing the sample is recommended. If hair from the scalp isn't available, a similar quantity of body hair can be used. References to head hair specifically mean scalp hair. Body hair includes all other hair types (facial, axillary, etc.).
Process Overview
The process in the lab for creating a drug test result involves four major steps: Accessioning, Screening, Extraction, and Confirmation.
During Accessioning, the sample is initially processed into the lab’s system. This phase includes checking if the sample was correctly sealed and sent, giving it a unique LAN (Laboratory Accessioning Number), and completing data entry not covered by electronic custody records.
Screening is a preliminary assessment to check for drugs. While Screening is efficient in excluding drug use in most samples, any positive results must be validated for legal acceptance. Any samples presumed positive in Screening need a follow-up confirmation.
Should a sample show a positive indication in Screening, additional hair from the original deposit is used for Extraction. Drugs are extracted at lower concentrations in hair than in other testing forms (urine, saliva), making hair screening complex.
Positive screenings undergo further checks using GC/MS, GC/MS/MS, or LC/MS/MS. Presumed positive samples are cleaned before validation if necessary. The whole process, from Accessioning to Confirmation, is checked following both CAP (College of American Pathologists) Hair guidelines and ISO / IEC 17025 accreditation.
