Hair Follicle Drug Testing - Gowen, OK

What it is, How it works

Hair analysis is now recognized as a potent resource for identifying drug and alcohol consumption. By trapping biomarkers within the fibers of the growing hair strand, hair can reveal a long-term history of substance use. When sampled close to the scalp, it can disclose a detection window for drugs and alcohol up to roughly three months. Collecting hair is straightforward, complex to tamper with, and convenient to transport.

A 1.5-inch sample comprising approximately 200 hair strands (similar to the diameter of a #2 pencil) near the scalp yields 100mg, the perfect amount for both screening and confirmation. For EtG, add-ons, and/or evaluations beyond ten panels, collecting 150mg is advised. Using a jeweler’s scale to weigh the specimen is recommended. If head hair isn't obtainable, an equivalent volume of body hair might be gathered. The term head hair refers exclusively to scalp hair, while body hair encompasses all other hair types (e.g., facial, axillary).

Process Overview

The laboratory processing of a drug test result hinges on four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning denotes the initial intake of a sample into the laboratory system. This step involves checking that the sample was correctly sealed and dispatched, assigning a unique LAN (Laboratory Accessioning Number), and conducting any missing data entry not facilitated by an electronic chain of custody system.

Screening conducts an initial rapid assessment for substance abuse. Although it is a cost-effective solution to exclude drug use in the bulk of samples, a positive result from the screening requires confirmation to be acceptable in court. Any samples indicating presumptive positivity during Screening necessitate a secondary confirmation.

If Screening yields a presumptive positive, additional hair is extracted from the primary sample for Preparation. This stage involves retrieving drugs from hair at concentrations substantially lower than other methodologies (e.g., urine or saliva), underscoring why hair drug testing is the hardest to accomplish.

Any confirmed positive screening outcome undergoes verification via GC/MS, GC/MS/MS, or LC/MS/MS. All samples indicating presumptive positivity are washed before confirmation if necessary. The comprehensive laboratory process, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection duration: Hair tests can identify drug usage spanning up to 90 days, whereas urine tests offer a more limited detection window.
• Resistance to evasion: Hair tests are notably resilient against attempts to cheat, enhancing the reliability of the results.
• Chronological data provision: Hair tests afford insights into patterns of drug use over a timeline, going beyond mere recent usage.

Limitations:

• Inability to pinpoint recent usage: It generally takes 5-7 days for drugs to manifest in hair.
• Expense: Hair testing is often pricier than other drug-testing options.
• Result variability: Variables like hair color and personal differences in hair growth may influence the concentration of drug residues present in the hair.

Note: Despite occasionally being dubbed "hair follicle tests", the actual analysis examines the hair strand, not the follicle beneath the scalp.
