Accredited Drug Testing provides comprehensive hair follicle drug screenings in Llano Grande, Texas. If you're seeking a hair test for drugs or alcohol, Accredited Drug Testing is an expert in this field with facilities throughout all cities Nationwide. A minimum length of 1.5 to 2 inches of hair from your head or body is generally required. These tests can identify drugs, alcohol/ETG, or other bespoke testing options.

Recently, hair follicle drug tests have gained prominence as a method for drug screening. More employers, courts, and substance abuse specialists now prefer hair tests over urine tests. Those with strict no-drug-use policies like employers, courts, and probation officers often rely on hair follicle testing. The main advantage is its extended detection window, often up to 90 days, and it’s collected under supervision making it nearly immune to deception. However, for detecting recent drug use within the past 5 days, urine tests remain the gold standard.

What it is, How it works

Hair testing is recognized as a robust method for identifying drug and alcohol use. Hair captures a long-term record of substances by embedding markers within the fibers of the developing strand. When taken close to the scalp, hair offers up to an approximate 3-month window for detecting alcohol and other substances. Hair collection is easy, not easily tampered with, and convenient to transport.

A 1.5-inch section of around 200 hair strands (comparable to a #2 pencil) nearest the scalp yields 100mg of hair, which is optimal for screening and confirmation. For EtG, additional analytes, and/or examinations beyond 10 panels, 150mg of the sample is advisable. We suggest using a jeweler’s scale to measure the sample. If scalp hair is not accessible, a similar amount of body hair can be collected. When mentioning head hair, it pertains only to scalp hair. Body hair includes all other hair forms (facial, axillary, etc.).

Process Overview

The laboratory procedure to process a drug test result encompasses four primary phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning consists of the sample’s initial integration into a lab’s system, including confirmation of the sample's proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any additional data entry that the electronic chain of custody system doesn’t provide.

Screening serves as an initial rapid assessment for illicit substances. Screening offers an inexpensive method to exclude substance use from most samples; however, to be court-admissible, any positive screen must be verified. Samples testing presumptively positive in Screening necessitate a secondary verification.

If Screening suggests a positive result, additional hair is retrieved from the original sample for Extraction. Here, substances are isolated from hair at considerably lower concentrations than other techniques (e.g., urine or oral fluid), making hair drug analysis the most challenging technique to execute.

Verification of any positive screen results is performed via GC/MS, GC/MS/MS, or LC/MS/MS. As needed, all samples presumed positive undergo a wash before confirmation. The comprehensive lab process from Accessioning to Confirmation is examined under CAP (College of American Pathologists) Hair standards and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

  • Extensive detection window: Hair drug tests can reveal drug consumption for up to 90 days, in contrast to urine tests which have a briefer detection timeline.
  • Difficult to falsify: Cheating a hair drug test is extremely challenging, enhancing result accuracy.
  • Historical insight: It can indicate a drug use pattern over time, not merely recent use.

Limitations:

  • Inability to detect recent usage: It needs roughly 5-7 days for substances to become noticeable in hair.
  • Expense: Generally, hair drug tests cost more than other drug testing techniques.
  • Outcome variations: Hair color and individual hair growth variations can influence the concentration of drug metabolites in the hair.

Note: Though often termed "hair follicle tests", these tests focus on analyzing the hair strand, not the scalp’s underlying hair follicle

Why Hair Follicle Testing Beats Urine Testing

Why Hair Testing Excels
In Llano Grande, TX, hair follicle testing outperforms traditional urine testing by offering broader detection capabilities. While urine tests can detect recent drug use, their window is limited. Hair testing, in contrast, provides a historical perspective, showcasing drug use over several months.

Superior Detection
With a longer window of detection, hair follicle tests offer a comprehensive overview of an individual's substance use history. This makes them more reliable for employers who need to maintain a drug-free environment and courts that require accurate evidence of substance use.

Greater Reliability
The enhanced detection range and reliability of hair tests make them an invaluable tool for various testing needs. While urine tests still play a role in short-term detection, hair tests provide a level of accuracy and reliability that is unmatched, making them the preferred choice in many cases.

Extended Detection Window

Lengthy Detection Period
The ability of hair follicle tests to detect drug use over an extended duration, up to 90 days, is a significant advantage in Llano Grande, TX. Employers benefit from this broader window to assess an individual's long-term substance use.

Comprehensive Substance History
Hair testing offers a detailed record of an individual's drug use pattern, providing a comprehensive view that urine tests can't match. With this approach, employers and legal entities can make more informed decisions based on a complete drug use history.

Better Insight for Employers
Employers seeking to understand a candidate's drug use history appreciate the insight provided by hair follicle tests. This comprehensive detection window allows for a more accurate assessment of long-term substance use, aiding in healthier employment decisions.

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.
