Hair Follicle Drug Testing - La Selva Beach, CA

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers, providing a comprehensive history of substance use over time. By collecting hair close to the scalp, a detection window of up to roughly three months can be offered for alcohol and other substances. Hair is easy to gather, relatively resistant to tampering, and straightforward to transport.

To obtain an optimal sample for testing, a 1.5-inch section of approximately 200 hair strands (roughly the thickness of a #2 pencil) is required, yielding 100mg of hair. For EtG, add-ons, or testing beyond the 10-panel range, 150mg of the hair sample is preferred. Using a jeweler’s scale to weigh the sample is advised. If scalp hair is not accessible, an equivalent amount of body hair may be utilized. Note that “head hair” refers specifically to scalp hair, whereas “body hair” encompasses all other hair types, such as facial or axillary.

Process Overview

The comprehensive laboratory procedure of a drug test involves steps such as Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step whereby a sample is integrated into a lab’s workflow. This step covers the confirmation that the sample was sealed and transported correctly, assigning a unique LAN (Laboratory Accessioning Number), and completing any further necessary data entry absent from an electronic chain of custody.

Screening acts as an initial check for substances of misuse. Although Screening is an affordable method to eliminate drug use for most samples, any positive results necessitate confirmation to be legally acceptable. Presumptively positive Screening samples require additional confirmation testing.

Should a sample indicate a presumptive positive during Screening, additional hair is extracted from the initial sample for the Extraction stage. Drugs are pulled from hair at a significantly reduced concentration compared to other methods (such as urine or oral fluid), which underscores the complexity of hair drug testing as a procedure.

Positive samples identified during Screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples are cleansed before confirmation if needed. The holistic laboratory journey from Accessioning through to Confirmation is aligned with the CAP (College of American Pathologists) Hair guidelines and the ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

• Prolonged detection period: Hair drug tests can detect drug consumption up to 90 days, contrasted with the shorter window of urine tests.
• Challenge to deceive: Cheating a hair drug test is notably difficult, enhancing result reliability.
• Historical usage data: It offers insight into drug usage patterns over time, not just recent activity.

Drawbacks:

• Inability to detect immediate use: Detection in hair takes approximately 5-7 days post-consumption.
• Expense: Hair drug tests usually incur higher costs than alternative testing methods.
• Variability in results: Hair color and individual growth disparities can impact drug metabolite levels found in hair.

Acknowledgment: Tests often named "hair follicle tests" actually assess hair strands instead of the follicles located beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In La Selva Beach, CA, hair follicle tests surpass traditional urine tests by offering enhanced detection precision and dependability. Hair analysis provides a broader detection timeline and is less susceptible to manipulation, offering employers a more comprehensive understanding of substance use.
