Accredited Drug Testing offers comprehensive hair follicle drug testing services in Carthage, Texas. For those needing hair drug or alcohol tests, our expertise lies in hair testing, with facilities across the U.S. ready for hair assessments. Generally, 1.5 to 2 inches of hair from the head or body suffices. Testing can detect drugs, alcohol/ETG, or be tailored to specific needs.

Over recent years, hair follicle drug tests have become more prevalent in drug testing modalities. Employers, judicial systems, and substance abuse experts increasingly prefer hair tests over urine tests. Employers with strict drug policies, courts, and probationary individuals rely on these tests. The advantage is a longer drug detection window—up to 90 days—using an observed process that's difficult to circumvent. Yet, for recent drug use within five days, urine tests prove more precise.

What it is, How it works

Hair testing is regarded as an effective method for identifying drug and alcohol consumption. The history of drug and alcohol use can be tracked over a long time frame by analyzing biomarkers embedded in a growing hair strand. A sample taken near the scalp can reveal drug and alcohol intake over a period of up to three months. Hair testing is easy to collect, somewhat resistant to tampering, and straightforward to ship.

Obtaining a 1.5-inch sample comprising approximately 200 hair strands (akin to the size of a #2 pencil) near the scalp yields 100mg of hair, ideally suited for screening and confirmation processes. For tests including EtG or those exceeding 10 panels, a specimen weighing 150mg is advisable. It’s recommended to weigh the specimen using a jeweler’s scale. If scalp hair is not available, a similar quantity of body hair can be utilized. By head hair, we specifically mean scalp hair, while body hair encompasses other types such as facial or axillary hair.

Process Overview

The laboratory processing of a drug test result involves four primary stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the preliminary stage where a sample enters the laboratory system. This step verifies the sample’s proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and completes any extra data entry that an electronic chain of custody system may lack.

Screening is an initial rapid evaluation for the presence of drugs of abuse. It serves as a cost-efficient method to exclude drug usage in most samples; however, a positive result from Screening necessitates confirmation for legal validity. Any samples with presumptively positive results in Screening require a secondary confirmation process.

If Screening suggests a presumptively positive result, more hair is extracted from the initial sample for further processing in Extraction. During Extraction, drugs are isolated from hair at a lower concentration compared to other methods (e.g., urine or oral fluid tests), which is why hair drug screening is among the more challenging methodologies.

Confirmation of any positive Screening result is done using GC/MS, GC/MS/MS, or LC/MS/MS techniques. Presumptive positive samples undergo washing before confirmation as necessary. The complete laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug use up to 90 days preceding, as opposed to urine tests with a more limited detection range.
  • Hard to manipulate: Cheating on a hair drug test is quite difficult, enhancing the reliability of the results.
  • Tracks historical use: Hair testing can illustrate a pattern of drug usage over time, rather than just recent consumption.

Limitations:

  • Inability to detect recent use: Detection in hair takes around 5-7 days post-exposure.
  • Expense: Hair drug tests generally incur higher costs compared to other testing methods.
  • Result variability: Factors like hair color and individual differences in hair growth can influence drug metabolite concentrations in hair.

Note: Although often termed as "hair follicle tests", the actual analysis is conducted on the hair strand and not the follicle underneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Carthage, TX, hair follicle testing provides several advantages over traditional urine tests. One key benefit is the test's ability to accurately detect drug use over a prolonged period. While urine tests are limited by shorter detection windows, hair tests reveal a more extensive substance use history.

Accuracy is a hallmark of hair testing, often superior to urine tests. The reliability of hair tests provides peace of mind for employers and stakeholders, as they ensure that detected substances reflect genuine usage rather than potential test tampering.

Extended Detection Window

One significant feature is the extended detection window of hair follicle testing in Carthage, TX. Unlike urine tests, which offer a shorter window, hair tests can reveal substance use for up to 90 days, providing a more comprehensive view of an individual's drug history.

For employers, the extended detection period of hair follicle tests offers a complete analysis of an employee's or job applicant's drug use. This more extended detection period helps make informed employment decisions based on reliable data.
Extended detection periods provide deeper insights into patterns of substance use.

Tamper-Resistant Testing Method
