In La Presa, Texas, Accredited Drug Testing offers reliable hair follicle drug testing. If you're looking for hair drug or alcohol testing, we are experts and have facilities in cities across the nation ready to conduct hair testing. Typically, 1.5 to 2 inches of hair from your head or body can be tested. Hair tests can detect drugs, alcohol/ETG, and offer other specialized options.

Hair follicle drug testing has become a prevalent method for drug screening in recent times. Employers, judicial systems, and substance abuse experts opt for hair testing over standard urine tests. Organizations with zero-tolerance policies, legal courts, and probation-monitoring programs rely on hair tests. The key advantage lies in its ability to detect drug use over an extended period, up to 90 days, through a monitored collection process, while being nearly fraud-proof. Urine tests remain unmatched for detecting recent drug use within a 5-day window.

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying the usage of drugs and alcohol. Hair captures a prolonged record of consumption by encasing biomarkers within the strands as they grow. When sourced close to the scalp, hair can reveal usage of alcohol and drugs for up to roughly three months. The collection of hair is straightforward, somewhat resistant to tampering, and easy to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (similar to the thickness of a #2 pencil) near the scalp will yield 100mg of hair, which is the preferred sample size for testing and verification. For EtG, add-ons, or tests exceeding 10 panels, a 150mg specimen is preferred. It is advisable to weigh the sample on a jeweler’s scale. Should scalp hair be unavailable, an equivalent amount of body hair may suffice. When mentioning head hair, we exclusively refer to scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

The laboratory analysis of a drug test is comprised of four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the preliminary handling of a specimen within a laboratory’s system. This process ensures the sample was securely sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and completes any supplemental data entry not provided by an electronic chain of custody system.

Screening constitutes a preliminary assessment for substances of abuse. Although Screening is an economical method for excluding drug use in the majority of samples, a positive outcome mandates confirmation to be legally admissible. Any samples that test presumptively positive in Screening necessitate a secondary confirmation.

Should a sample appear positive in the Screening phase, additional hair is extracted from the original specimen and readied for Extraction. Here, drugs are removed from hair at significantly lower concentrations compared to other methods (such as urine or oral fluid), making hair drug screening the most challenging method to undertake.

Confirmation of any positive screening result is conducted using GC/MS, GC/MS/MS, or LC/MS/MS. Presumptive positive samples undergo washing before confirmation, if necessary. The complete laboratory process from Accessioning to Confirmation is reviewed in line with the CAP (College of American Pathologists) Hair standards and accreditation to ISO / IEC 17025 benchmarks.

Advantages of hair drug testing:

  • Extended detection period: Hair drug tests can identify drug use for up to 90 days, while urine tests offer a smaller detection period.
  • Hard to manipulate: It is very challenging to deceive a hair drug test, ensuring more reliable results.
  • Historical insights: It provides a trend of drug use over a duration, rather than just recent use.

Limitations:

  • Inability to detect recent use: It takes about 5-7 days for drugs to show up in hair.
  • Expense: Hair drug tests are typically more costly than other drug testing methods.
  • Result variability: Factors like hair color and individual hair growth rates can influence the concentration of drug metabolites present.

Note: Despite being commonly called "hair follicle tests", the analysis focuses on the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing significantly outshines urine testing in La Presa, TX, by offering superior detection accuracy and reliability. One advantage is its ability to detect drugs over a longer period, extending up to 90 days, compared to the shorter window with urine tests. This provides a more complete picture of substance use. Hair testing is nearly impossible to tamper with, ensuring the integrity of results and aiding establishments striving for drug-free environments.

Organizations find hair tests highly advantageous as they reduce the chances of false negatives often seen in urine tests. This makes hair follicle testing a more dependable choice. Moreover, while urine testing is suitable for recent consumption detection, businesses demanding stringent substance policies benefit greatly from the comprehensive review provided by hair testing.

Extended Detection Window

A major benefit of hair follicle testing in La Presa, TX, is its extended detection window. By capturing substance use over the past 90 days, this test provides a detailed history that standard urine tests can't match. Employers gain insights into sustained substance habits, aiding informed decisions about hiring or interventions. This long detection window is valuable for companies needing a thorough view into applicant or current employee behaviors.

With its ability to cover such an extensive period, hair testing is indispensable for maintaining transparent workplace conditions. As businesses seek reliable evidence of an individual's history, hair follicle tests offer a comprehensive examination, equipping employers with the data required to support a drug-free setting while also potentially reducing the risk of hiring individuals whose consumption might impact work performance.

Tamper-Resistant Testing Method

Hair follicle testing reduces the risks of sample tampering, guaranteeing reliable outcomes in La Presa, TX. This is crucial for employers who require unquestionable results to ensure company policies are strongly adhered to. Because altering a hair sample is far more difficult than a urine sample, this testing method is trusted for its authenticity and steadfastness in providing accurate data consistently.

In environments where policy compliance and safety are paramount, the risk of adulteration in traditional testing methods concerns management. Hair testing offers a solution to this issue, making it nearly impervious to deceit. Employers can confidently rely on these results, knowing they reflect true substance use, thus supporting the integrity of workplace policies and employee wellbeing.

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.

It is frequently selected for legal, compliance, and custody-related documentation.
A small section of hair is cut by a trained collector in a discreet, controlled manner. The sample is sealed, documented, and sent to the laboratory under established chain-of-custody procedures so that the results can be defended if they are ever challenged.
