Hair Follicle Drug Testing - Hereford, PA

What it is, How it works

Hair analysis has emerged as an effective means for uncovering drug and alcohol consumption. Hair retains a lasting record of substances by ensnaring biomarkers within its fibers as it grows. Gathering hair near the scalp offers an approximately 3-month window for detecting substances. Hair is straightforward to collect, challenging to tamper with, and simple to transport.

A 1.5-inch segment of around 200 hair strands (equivalent to a #2 pencil's width) closest to the scalp yields 100mg of hair, which is the preferred sample size for screening and validation. For EtG, additional tests, and/or panels exceeding 10, a 150mg sample is preferred. We advise utilizing a jeweler’s scale to measure the specimen. If scalp hair isn't available, a matching quantity of body hair may be sampled. When referencing head hair, it specifically pertains to scalp hair alone. Body hair signifies all other hair types (e.g., facial, axillary).

Process Overview

The drug testing protocol in the lab encompasses four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning covers the preliminary handling of a sample within a lab’s framework. This step ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and finalizes any remaining data input absent in the electronic custody record.

Screening entails an initial swift assessment for harmful substances. Despite being cost-efficient for excluding drug use in most samples, court admissibility requires confirmation of a positive screen. Samples presumed positive in Screening necessitate a confirmatory assessment.

If a sample signals a presumptive positive during Screening, more hair is extracted from the original specimen for Extraction. At this juncture, drugs are retrieved from hair at a significantly reduced level compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging to conduct.

Validation of any positive screening finding is performed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples with preliminary positive results undergo washing before confirmation when necessary. The holistic process, spanning Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair classification and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can unveil substance use for up to 90 days, compared to urine tests with a briefer detection span.
• Hard to manipulate: Hair drug tests are difficult to bypass, enhancing the accuracy of results.
• Reveals historical patterns: They offer a comprehensive drug usage pattern over time, beyond recent activity.

Limitations:

• Incapable of detecting immediate use: Drugs become noticeable in hair approximately 5-7 days post-consumption.
• Expense: Hair drug tests typically incur greater costs than alternate testing approaches.
• Result variability: Factors like hair hue and personal variations in hair growth can influence drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", the test itself examines the hair strand, not the follicle beneath the scalp
