Accredited Drug Testing provides extensive hair follicle drug testing services in Blessing, Texas. Whether you need to test for drugs or alcohol, our specialty in hair analysis allows us to offer expert services, with testing sites available in all cities across the Nation. To conduct the test, typically 1.5 to 2 inches of hair from your head or body is needed. These tests can identify drugs, alcohol/ETG, or be customized for other options.

Recently, the hair follicle drug test has increasingly become a preferred method for drug detection. A growing number of employers, judicial systems, and substance abuse experts now favor hair tests over conventional urine tests. Employers enforcing strict no-drug policies, as well as courts and probation agencies, use hair tests. These tests offer a key advantage: an extended drug detection period of up to 90 days, undergoes direct observation during collection, and are virtually tamper-proof. However, urine tests remain the best choice for detecting recent drug use within the past 5 days.

What it is, How it works

The utilization of hair testing is increasingly regarded as an effective method for identifying drug and alcohol consumption. Hair encapsulates a historical record of alcohol and drug intake, capturing markers within the hair shaft as it forms. When sourced near the scalp, hair samples can provide an approximate 3-month detection span for various substances. Collection of hair is straightforward, relatively resistant to tampering, and convenient to transport.

A sample measuring 1.5 inches and comprising approximately 200 strands of hair (comparable to the diameter of a #2 pencil) near the scalp yields 100mg of hair, which is the optimal quantity for both screening and verification. For EtG, additional tests, and/or tests exceeding 10 panels, a firmer recommendation is 150mg of the sample. We suggest using a jeweler’s scale for measuring the specimen. In cases where scalp hair is absent, a comparable amount of body hair is suitable for collection. When discussing head hair, reference is made exclusively to scalp hair. Body hair includes all other varieties (facial, axillary, etc.).

Process Overview

The four fundamental steps in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the step where a sample is initially processed into the lab's system, ensuring the sample was properly sealed and shipped, assigning a unique LAN (Laboratory Accessioning Number), and performing any other data entry not handled by an electronic chain of custody.

Screening is a preliminary, cost-effective measure to identify potential drug use across most samples. For court admissibility, positive screens require confirmation. Samples with presumptive positive results during Screening must undergo definitive confirmation.

In cases where Screening results are presumptive positives, additional hair from the original sample is prepared for Extraction. Drugs are drawn from hair concentrations lower than those in alternative methods (like urine or saliva), underscoring the complexity of hair drug screening.

Confirmation of any positive Screening is accomplished via GC/MS, GC/MS/MS or LC/MS/MS techniques. All presumptive positives undergo a wash as needed before Confirmation. The complete lab procedure, ranging from Accessioning to Confirmation, is conducted under CAP (College of American Pathologists) Hair guidelines and in alignment with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can reveal drug use spanning up to 90 days, unlike urine tests which have brief detection periods.
  • Hard to tamper with: Cheating a hair drug test is notably challenging, enhancing result accuracy.
  • Reveals usage patterns: It delineates drug use trends over time rather than just recent consumption.

Limitations:

  • Lacks immediate detection: Drugs take about 5-7 days to appear in hair samples.
  • Expense: Hair drug testing often incurs higher costs than other drug testing techniques.
  • Result variability: Elements like hair color and individual hair growth differences can influence the concentration of drug residues in hair.

Note: The so-called "hair follicle tests" actually assess the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

For residents of Blessing, TX, hair follicle tests offer clear advantages over urine tests. The primary benefit lies in detection accuracy. Hair tests trace substances over a longer timeline, giving a full picture of drug use. Unlike urine tests, which are limited to recent usage, hair assessments provide a broader analysis of behavior.

Extended Detection Window

While urine tests catch recent drug consumption, the hair follicle approach gives a broader view. The advantage of this extended window is essential for companies maintaining drug-free workplaces, providing a fuller picture.

Biomarkers and Pharmacokinetics: The identification and validation of reliable biomarkers and pharmacokinetic studies are fundamental aspects of drug testing and analysis. The impact of hair treatments on the oxidation/decomposition of drugs in hair was also explored, as the long-term fate of drugs incorporated in the keratin matrix. Furthermore, the SoHT meeting in Verona featured research on the identification and quantification of alcohol abuse biomarkers, their stability, and their correlation with exposure and other biomarkers.

Forensic Applications and Interpretation: One of the vital objectives of hair testing is its application in forensic investigations and legal proceedings. The SoHT meeting in Verona emphasized the significance of rigorous interpretation of analytical results and the need for standardized protocols. Manuscripts in this section present advancements in forensic toxicology, and have explored the challenges posed by emerging designer drugs and strategies to combat their proliferation.

Frequently Asked Questions

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

It is frequently used for legal and court requirements, long-term monitoring, and high-trust workforce screening.
Standard hair drug testing typically reflects drug use over approximately a 90-day period, based on the length of hair collected at the time of testing. Longer hair can sometimes reflect a longer time frame, and extremely short hair can reduce that window.
