Hair Follicle Drug Testing - Faith, AR

What it is, How it works

Hair analysis is increasingly recognized as a potent method for identifying drug and alcohol usage. Hair strands capture a long-term record of alcohol and drug presence by embedding biomarkers in their fibers as they grow. When cut near the scalp, hair can reveal drug and alcohol detection for a period of up to three months. The collection of hair is straightforward, resistant to tampering, and easy to transport.

A sample measuring 1.5 inches in length with roughly 200 hair strands (comparable to a #2 pencil's thickness) near the scalp yields 100mg, which is optimal for screening and confirmation. For EtG, additional testing, or panel tests exceeding 10, 150mg of the sample is advised. It's suggested to measure the weight of the sample using a jeweler’s scale. If scalp hair is not available, an equivalent amount of body hair is acceptable. "Head hair" refers exclusively to scalp hair, while "body hair" includes all other hair types (facial, axillary, etc.).

Process Overview

Drug test results in the lab undergo four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample within a lab's system. This step encompasses checking the sample's seal and proper shipping, assigning it a unique LAN (Laboratory Accessioning Number), and completing any missing information not provided by an electronic chain of custody.

Screening performs an initial rapid assessment for drug presence. Although it's an economical way to exclude drug use in most cases, positive screens must be verified to be court-admissible. Any sample that shows a presumptive positive at Screening needs subsequent confirmation.

For samples flagged as presumptively positive during Screening, an additional portion of the specimen is used for Extraction. This step involves retrieving drugs from hair at substantially lower levels than other techniques (like urine or saliva), which is why hair drug testing is the most challenging to execute.

Confirmation of any positive screen is achieved through GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples marked presumptive positive are cleansed before confirmation if necessary. The full laboratory procedure, from Accessioning to Confirmation, is subjected to review under the CAP (College of American Pathologists) Hair designation alongside the ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug usage for as long as 90 days, unlike urine tests which detect for a shorter span.
• Hard to manipulate: Hair drug tests are notoriously hard to cheat, resulting in more reliable outcomes.
• Historical usage pattern: This method can exhibit the history of drug use over time, not just recent consumption.

Limitations:

• Inability to detect recent intake: Drugs become detectable in hair only after approximately 5-7 days.
• Expense: Hair drug testing tends to be more costly compared to other methodologies.
• Result variability: Elements like hair color and individual hair growth can alter the levels of drug metabolites in hair.

Note: Commonly called "hair follicle tests", the evaluation focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Faith, AR, hair follicle tests surpass the efficacy of traditional urine tests. Their ability to detect substance use across a more extended period offers superior accuracy, making them a more reliable option for both employers and legal entities seeking comprehensive screening.
