Hair Follicle Drug Testing - Diamond Springs, CA

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. Hair serves as a long-term record for alcohol and drugs by embedding biomarkers within the fibers of the hair as it grows. When gathered from the area near the scalp, hair can offer an approximately 3-month timeframe for detecting alcohol and drugs. Hair collection is straightforward, somewhat resistant to tampering, and easily transportable.

A 1.5-inch segment comprised of around 200 hair strands (similar in size to a #2 pencil) near the scalp supplies 100mg, which is the optimal amount for screening and verification. For EtG, additional tests, and/or tests beyond 10 panels, 150mg of hair is advised. It is suggested to weigh the specimen using a jeweler’s scale. If scalp hair is not available, a comparable amount of body hair is acceptable. In terms of head hair, this specifically means scalp hair. Body hair includes all other kinds (such as facial and axillary hair).

Process Overview

The process of analyzing a drug test outcome in the laboratory includes four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the first step where a sample is recorded into the laboratory system. This phase checks that the sample was sealed and sent correctly, assigns an Arbitrary LAN (Laboratory Accessioning Number), and completes additional data entry absent from an electronic chain of custody.

Screening offers an initial swift evaluation for drug abuse presence. While Screening is a cost-efficient method to deduce the non-use of drugs in most samples, a positive screen requires confirmation for legal acceptability. Samples showing presumptive positivity in Screening necessitate an additional verification step.

When a sample appears presumptively positive during Screening, additional hair is extracted from the original sample for the Extraction phase. At this stage, drugs are extracted from hair in significantly lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug screening the most complex testing method.

Verification of any positive screening result is performed using GC/MS, GC/MS/MS, or LC/MS/MS. Before verification, all presumptive positive samples undergo a cleaning as necessary. The full laboratory process from Accessioning to Verification is scrutinized under the CAP (College of American Pathologists) Hair designation and adheres to the accreditation of ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection window: Hair drug exams can trace drug use up to 90 days, while urine tests offer a narrower detection window.
• Hard to deceive: Deception is very challenging with a hair drug test, leading to more precise outcomes.
• Supplies historical usage data: It can illustrate a trend of drug consumption over a duration, not merely the most recent usage.

Limitations:

• Unable to detect recent usage: It requires about 5-7 days for substances to show up in hair.
• Expense: Hair drug examinations generally incur higher costs compared to other drug testing methods.
• Result variability: Factors like hair color and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests", the test evaluates the hair shaft rather than the follicle beneath the scalp
