Accredited Drug Testing offers comprehensive hair follicle drug testing services in Juarez, Texas. For those seeking a hair drug or alcohol analysis, Accredited Drug Testing excels in hair testing and boasts testing centers in every major city across the nation where hair tests can be conducted. Typically, you need to have between 1.5 to 2 inches of hair on your head, although body hair can also be used in most scenarios. Hair samples can be examined for drugs, alcohol/ETG, or other customized hair testing options.

Recently, the approach to conducting drug tests has increasingly involved the use of hair follicle drug assessments. Many employers, courts, and substance abuse experts are now opting for hair drug tests instead of traditional urine tests. Hair follicle drug assessments are favored by employers with strict no-drug policies, judicial systems, and probationary individuals. The principal advantage of hair follicle drug testing is its extended drug use detection window—up to 90 days—gathered in an observed process that's nearly impossible to manipulate. However, for detecting drug use within the immediate past 5 days, urine tests remain the most precise.

What it is, How it works

Hair analysis is recognized as an effective method for identifying drug and alcohol consumption. By embedding biomarkers in the strands as the hair grows, it offers a prolonged timeline of substance use. Collected near the scalp, hair can reveal drug and alcohol consumption over nearly three months. It's easy to gather, challenging to tamper with, and simple to send for testing.

A 1.5-inch segment comprising approximately 200 hairs (around the diameter of a #2 pencil) from the scalp yields 100mg, the perfect amount for preliminary and confirmatory tests. If conducting EtG, additional, or more than 10-panel tests, 150mg is ideal. Use a jeweler's scale for precision. If scalp hair is not an option, a comparable quantity of body hair may be utilized. By scalp hair, we mean hair from the head exclusively. Body hair encompasses all other varieties (facial, axillary, etc.).

Process Overview

The laboratory process of drug testing involves four key steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step of logging a sample into a lab's records. This ensures the sample was properly sealed and sent, assigns it a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not handled by an electronic chain of custody system.

In Screening, an initial rapid check for drug use occurs. While Screening is cost-efficient for excluding drug use in most samples, a positive result requires confirmation for legal validation. Samples preliminarily positive in Screening need a follow-up confirmation.

For any sample testing positive in the Screening phase, additional hair from the specimen is readied for Extraction. Drugs are drawn out from hair in lower concentrations compared to other methods (e.g., urine or oral fluid), which makes hair drug screening a particularly challenging process.

Any positive results from Screening undergo Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS methods. Presumptive positive samples are cleansed prior to needed confirmations. The complete lab procedure from Accessioning to Confirmation is curated under both the CAP (College of American Pathologists) Hair category and compliance with ISO / IEC 17025 standards.

Advantages of hair drug testing:

  • Extended detection period: Hair drug testing reveals drug use for as long as 90 days, offering advantages over urine tests with shorter detection periods.
  • Hard to evade: Tampering with hair drug tests is exceedingly difficult, ensuring more trustworthy results.
  • Shows historical usage: Highlights a drug usage pattern over time, not solely recent consumption.

Limitations:

  • Cannot identify recent intake: Drugs take about 5-7 days to appear in hair.
  • Higher cost: Hair tests usually cost more than alternative drug testing techniques.
  • Result variability: Hair color and individual growth rates may influence the drug metabolite concentrations.

Note: Although commonly called "hair follicle tests", the test actually examines the hair strand and not the follicle beneath the skin.

Why Hair Follicle Testing Beats Urine Testing

In Juarez, TX, understanding why hair follicle testing outperforms urine testing is key. Hair testing provides superior detection accuracy, reliably identifying drug use over an extended timeframe.

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. The pitfalls encountered when the exogenous/endogenous nature of a substance is questioned were presented and discussed. The special issue presents also manuscripts that delve into the ethical implications of drug testing in drug facilitated sexual assaults.

Clinical Applications of hair testing are witnessed by the insight on environmental tobacco smoke exposure, assessed by hair analysis in a population of students and the study of in utero-exposure to drugs of abuse through neonatal hair analysis. Exposure to drugs was also important in cases of child abuse/neglect, when the clinical purpose of hair testing merge with its forensic applications.

The legal framework surrounding hair testing and the achievement of guidelines to ensure fairness, accuracy, and confidentiality in drug testing practices have also been discussed,and the SoHT consensus on general hair testing and testing for drugs of abuse was presented at the meeting and published as a Letter to the Editor.

Frequently Asked Questions

A hair follicle drug test analyzes a small sample of hair to detect a history of drug use over time. Because drug metabolites are incorporated into hair as it grows, this method can show patterns of use instead of just recent exposure. 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.
Hair drug testing commonly screens for marijuana/THC, cocaine, opiates/opioids, amphetamines/methamphetamines, and PCP. In many cases, additional expanded panels may be requested to include other substances.
Yes. If the donor's head hair is too short or unavailable, body hair may be collected as an alternative. The collector will document the source of the sample. This allows testing even for individuals with recently cut or shaved head hair.
Yes. Hair drug testing is commonly used in court, probation, custody, and compliance matters because the collection process follows a documented chain of custody and the analysis is performed by a certified laboratory. Results are provided in a form that can be reviewed by legal and administrative authorities.
Yes. Individuals, parents, attorneys, employers, and probation programs can all request hair drug testing. A doctor's order is not required. Results are confidential and released only to the authorized requesting party.
