Accredited Drug Testing offers comprehensive hair follicle drug testing services in Tanglewood, Texas. Whether you require a hair drug or alcohol test, we specialize in hair testing with facilities in cities across the Nation. Typically, you'll need 1.5 to 2 inches of hair from the crown or body for testing. Our services include tests for drugs, alcohol/ETG, and personalized hair testing options.

In recent trends, hair follicle drug tests have become increasingly popular for drug screening. Employers, courts, and Substance Abuse experts often prefer this method over traditional urine tests. Hair tests are favored for zero-tolerance drug policies and probation requirements. They offer a longer detection window, up to 90 days, are collected under observation, and are nearly impossible to tamper with. However, for recent drug use within the last 5 days, urine tests remain more precise.

What it is, How it works

Analyzing hair has gained recognition as a potent method for identifying drug and alcohol consumption. Hair retains biochemical markers within its fibers, offering an extended history of substance use as hair grows. When hair is retrieved near the scalp, it can indicate substance use over a period extending up to roughly 90 days. Collecting hair is straightforward, hard to tamper with, and convenient to transport.

A segment of hair measuring 1.5 inches and containing around 200 hairs (similar to the diameter of a #2 pencil) nearest to the scalp ensures a sample weighing approximately 100mg, which is optimal for screening and verification. For EtG, additional assessments, and tests that exceed 10 panels, a 150mg specimen is advised. It's recommended to weigh the sample using a jeweler's scale. If scalp hair isn't available, a comparable quantity of body hair can be utilized. "Head hair" specifically refers to scalp hair solely. "Body hair" encompasses all other hair types (facial, axillary, etc.).

Process Summary

The drug test laboratory processing comprises four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the preliminary handling of a sample to integrate it into the laboratory's system. This entails confirming the sample was properly sealed and shipped, allocating a random LAN (Laboratory Accessioning Number), and finalizing any further data input not managed by an electronic chain of custody setup.

Screening consists of an initial rapid detection of abused substances. Screening is an economical approach for excluding drug use in most samples, yet a positive screen necessitates confirmation for court acceptance. Any samples that appear positive in Screening must undergo supplementary confirmation.

If Screening yields a presumptive positive, further hair is extracted from the initial sample and prepped for Extraction. This phase involves isolating drugs from hair at substantially lower concentrations compared to other methods (e.g., urine or oral fluid), which is why hair screening is the most technically challenging method.

Confirming any positive screen is achieved using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples presumed positive are cleaned before confirmation as required. From Accessioning to Confirmation, every laboratory stage conforms to both CAP (College of American Pathologists) Hair specifications and ISO / IEC 17025 accreditation standards.

Benefits of hair drug testing:

  • Extended detection period: Hair drug tests recognize drug use up to 90 days, while urine tests have a shorter period.
  • Low chance of deception: Cheating a hair drug test is highly challenging, ensuring more reliable results.
  • Offers past usage data: It provides a history of drug use over time, not just recent consumption.

Drawbacks:

  • Inability to identify recent use: Detecting drugs in hair takes around 5-7 days.
  • Expense: Hair drug tests are typically costlier than other drug testing methods.
  • Result variations: Aspects such as hair color and individual hair growth variations can impact drug metabolite levels in hair.

Note: The often-used term "hair follicle tests" actually pertains to the analysis of the hair strand, not the follicle beneath the scalp.

What's New In Hair Follicle Drug Testing according to the Hair Drug Testing Experts

With its multidisciplinary nature, hair testing brings together researchers, scientists, and experts from various domains to develop innovative techniques, explore new methodologies, and address emerging concerns, responding to the ever-evolving challenges of drug abuse, therapeutic drug monitoring, and environmental exposures to pollutants.

The joint meeting of the Society of Hair Testing (SoHT) and the Italian Group of Forensic Toxicologists (GTFI) was organized in Verona, June 8–10, 2022, and hosted by the Legal Medicine team of the Verona University Hospital, directed by Franco Tagliaro together with Federica Bortolotti and Rossella Gottardo.

It served as a prominent platform for knowledge exchange and collaboration, facilitating groundbreaking advancements in hair testing and analysis. In this special issue of Drug Testing and Analysis, we aim to showcase the remarkable manuscripts presented at this significant event, shedding light on the latest research and highlighting the future directions in this field.

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.
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.
