Accredited Drug Testing offers comprehensive hair follicle drug testing services in University City, Missouri. For those requiring a hair drug or alcohol test, Accredited Drug Testing excels in hair testing with locations in every city across the country where a hair test can be conducted. Generally, a minimum of 1.5 to 2 inches of hair is necessary from either the head or body. Hair tests can be processed for drugs, alcohol/ETG, or tailored hair testing solutions.

Lately, drug test methods increasingly incorporate hair follicle tests. A growing number of employers, legal entities, and Substance Abuse experts prefer hair testing over standard urine testing. Employers with zero-tolerance drug policies, courts, and individuals on probation utilize hair follicle drug tests. Their key advantage is an extended detection period of approximately 90 days, ensured through observed sample collection, making them almost impossible to evade. Nonetheless, when detecting recent drug use within the past 5 days, urine testing remains the most precise method.

What it is, How it works

Hair analysis is increasingly recognized as an effective method for detecting substance and alcohol consumption. It provides an extended record of alcohol and drug use by capturing biomarkers within the hair's fibers. When hair is cut near the scalp, it can offer an approximately three-month detection period for substances. Collecting hair samples is straightforward, challenging to tamper with, and easy to mail.

A 1.5-inch sample with around 200 hair strands (comparable to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, optimal for testing and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advisable. The specimen should be weighed using a jeweler’s scale. If scalp hair isn't available, an equivalent amount of body hair may be used. Reference to head hair pertains only to scalp hair, while body hair encompasses all other types (facial, axillary, etc.).

Process Overview

Processing a drug test result in the lab involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails initially processing a sample into the lab's system. This step verifies correct sealing and shipping of the sample, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry absent from an electronic chain of custody system.

Screening performs a quick preliminary test for substance abuse. Though cost-effective in excluding drug use for most samples, a positive screen must be confirmed for court use. Any samples showing a presumptive positive in Screening require further confirmation.

If a sample shows a presumptive positive at the Screening phase, additional hair is drawn from the original sample for Extraction. In this phase, drugs are extracted from hair at significantly lower concentrations than other methods (like urine or oral fluid), explaining the intricacy of hair drug screening.

Confirmation of any positive screening outcome is done through GC/MS, GC/MS/MS or LC/MS/MS. Presumptive positive samples undergo washing before confirmation as necessary. The complete lab process from Accessioning to Confirmation undergoes review under the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Long detection period: Hair drug tests identify drug use for as long as 90 days, unlike urine tests with shorter detection periods.
  • Difficult to tamper with: Hair drug tests are nearly impossible to cheat, ensuring greater result accuracy.
  • Shows usage patterns: They provide a chronological pattern of drug use, not just recent consumption.

Limitations:

  • Cannot detect recent consumption: Drugs generally become detectable in hair after about 5-7 days.
  • Expense: Hair drug tests typically cost more than other testing methods.
  • Result discrepancies: Factors like hair color and individual hair growth differences may influence drug metabolite concentration in hair.

Note: Often called "hair follicle tests", the test actually analyzes the hair strand, not the follicle itself beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In University City, MO, hair follicle testing presents several advantages over traditional urine tests. One of the most notable benefits is its superior detection accuracy. Compared to urine tests, hair tests offer a broader insight into an individual's substance history, detecting drug use over a longer period with greater reliability.

Another crucial advantage is the enhanced reliability of hair testing in identifying substances. Unlike urine tests, which can be more easily affected by recent lifestyle changes or temporary abstinence, hair testing provides a more stable and consistent measure of substance use over time.

Extended Detection Window

In University City, MO, hair follicle tests offer an extended detection window when assessing drug use. They provide the ability to identify substance use up to 90 days prior, far exceeding the capabilities of traditional urine tests, which typically only detect recent use.

This longer detection period grants employers a comprehensive view of an employee or applicant's substance use history, aiding in more informed hiring and management decisions. This extended timeline ensures that employers can maintain workplace integrity and safety.

Tamper-Resistant Testing Method

Hair follicle testing in University City, MO, is known for its tamper-resistant qualities. Unlike urine tests, hair tests significantly decrease the risk of sample adulteration or substitution, ensuring the integrity of the results.

These tests provide reliable and unquestionable outcomes, enhancing confidence in their findings. The challenge of tampering with hair samples confirms the test’s position as a trustworthy tool for detecting substance use, ultimately protecting the accuracy of test results.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time.
