Hair Follicle Drug Testing - Allentown, PA

What it is, How it works

The analysis of hair has become recognized as a potent method for detecting drug and alcohol usage. Hair captures a long-term record of substance use by trapping biomarkers in the fibers of the hair as it grows. A sample taken close to the scalp can provide up to a 90-day detection timeline for both alcohol and drugs. Hair is easy to collect, relatively challenging to tamper with, and simple to transport.

A hair sample of 1.5 inches, comprising approximately 200 strands (similar in size to a #2 pencil) near the scalp, yields 100mg, which is the optimal quantity for screening and confirmation. For tests such as EtG, add-ons, or panels exceeding 10, 150mg of the specimen is advised. Utilizing a jeweler’s scale to measure the specimen is recommended. If scalp hair cannot be obtained, an equivalent amount of body hair is permissible. References to head hair denote solely scalp hair, whereas body hair encompasses other types (facial, axillary, etc.).

Process Overview

The core stages in processing a drug test result in a laboratory are Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial phase of integrating a sample into a laboratory's framework. This step ensures the sample is sealed and conveyed appropriately, allocates a random LAN (Laboratory Accessioning Number), and concludes any remaining data entry absent from electronic chain of custody systems.

Screening provides a preliminary drug abuse assessment. Although Screening is an economical approach to dismiss drug presence in most samples, a positive result demands confirmation for court admissibility. Samples producing a presumptive positive in Screening necessitate additional verification.

Presumptive positive samples in Screening prompt the extraction of more hair from the original specimen for preparation in Extraction. In this phase, drugs are taken from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), accounting for the complexity of hair drug screening.

Confirmation of any positive outcome from screening involves methods like GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples undergo washing before confirmation if needed. The entire sequence from Accessioning to Confirmation adheres to both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 certification standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, compared to the shorter detection window of urine tests.
• High difficulty in falsification: Manipulating hair drug tests is highly complex, enhancing result accuracy.
• Retrospective data provision: It reveals a pattern of drug consumption over an extended period, beyond recent use.

Limitations:

• Inability to detect recent use: Drugs require approximately 5-7 days to become evident in hair.
• Expense: Hair drug tests often incur higher costs than alternative methods.
• Outcome variability: Factors like hair color and individual growth rates can influence drug metabolite concentrations in hair.

Note: Tests often called "hair follicle tests" actually assess the hair strand rather than the follicle beneath the scalp

Why Hair Follicle Testing Beats Urine Testing

When comparing hair follicle testing vs. urine tests in Allentown, PA, it's clear that hair testing offers superior detection capabilities. With a longer detection window, hair tests reveal repeated drug use patterns more effectively than urine tests, which only show recent use.

• Detection Period: Hair tests detect drug use over months, while urine tests are limited to days.
• Reliability: Hair tests are difficult to tamper with, unlike urine tests which can be manipulated.

Extended Detection Window

One of the chief benefits of hair follicle drug testing in Allentown, PA, is its extended detection window. Hair tests can screen for substances over a timeframe of up to 90 days, offering a more comprehensive overview than other testing methods.

This prolonged detection window is invaluable for employers seeking an in-depth view of an applicant's or employee's substance usage history, ensuring they make informed decisions regarding new hires and current staff.

Tamper-Resistant Testing Method

Hair follicle testing in Allentown, PA, boasts a robust tamper-resistant method, ensuring that test results remain reliable and untainted. Unlike urine tests, which can be diluted or altered, hair tests prevent manipulation through their direct sample collection approach.

This tamper-resistance guarantees that the results are both trustworthy and conclusive, minimizing the risk of false-negative outcomes due to sample adulteration or substitution.
