In Defiance, Missouri, Accredited Drug Testing offers comprehensive testing through hair follicle analysis. As specialists in hair drug and alcohol testing, we have a network of centers across cities Nationwide. Typically requiring 1.5 to 2 inches of hair on the crown or body, these tests can detect drugs, alcohol/ETG, and offer other tailored testing solutions.

Hair follicle drug testing has become a prevalent method for drug screening in recent years. Employers, courts, and substance abuse experts are leaning towards hair tests over urine tests. Employers with zero-tolerance drug policies, courts, and those on probation often prefer this method due to its extended detection period, which can last up to 90 days. Though the urine test remains more accurate for recent drug use, the hair test is nearly cheat-proof and observed during collection.

What it is, How it works

The use of hair testing has emerged as an effective method for identifying drug and alcohol consumption. Hair serves as a chronicling medium for detecting the presence of alcohol and other substances through the capture of biomarkers within the hair fibers. Collecting hair samples near the scalp allows detection for up to three months for alcohol and various drugs. Hair collection is straightforward, harder to tamper with, and convenient to transport.

A sample measuring 1.5 inches, consisting of around 200 hair strands (comparable to the size of a #2 pencil), is necessary to produce 100mg of hair, which is optimal for assessment and verification. For EtG, additional testing, and/or panels exceeding ten, a 150mg specimen is advisable. We advise using a jeweler’s scale to weigh the specimen. If scalp hair is inaccessible, a corresponding quantity of body hair can be used. In this context, head hair signifies scalp hair only, whereas body hair encompasses other types of hair (like facial, underarm, etc.).

Process Overview

The laboratory analysis of a drug test result comprises four essential phases: Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially processed into the laboratory system, ensuring that it was sealed and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and fulfilling any supplemental data entry not facilitated by an electronic chain of custody system.

Screening constitutes an initial rapid assessment for substances of abuse. Though Screening offers a cost-efficient means to eliminate drug consumption across numerous samples, confirmation is required for positives to be valid in legal proceedings. Samples that are presumptively positive in Screening necessitate confirmation.

When a sample is deemed presumptively positive during Screening, additional hair is taken from the original sample and prepped for Extraction. In this stage, substances are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or saliva), highlighting the complexity and precision required in hair drug screening.

Confirmation of any positive screening result is executed using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positive samples are cleansed before final confirmation as necessary. The complete laboratory procedure, from Accessioning to Confirmation, undergoes evaluation under both the CAP (College of American Pathologists) Hair designation and ISO/IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Long detection window: Hair drug tests detect drug use up to 90 days, unlike urine tests, which have a briefer detection period.
  • Difficulty to cheat: It's quite challenging to manipulate a hair drug test, ensuring higher accuracy in results.
  • Provides historical data: This method can illustrate a usage pattern over an extended duration, rather than recent activity only.

Limitations:

  • Cannot detect recent use: Drugs only become detectable in hair approximately 5-7 days post-consumption.
  • Cost: Hair drug testing is generally pricier compared to alternative drug testing techniques.
  • Variations in results: Elements like hair color and individual differences in hair growth may impact drug metabolite concentration in hair.

Note: The term "hair follicle tests" is commonly used, though the analysis targets the hair strand instead of 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.

Novel Analytical Techniques: The Verona meeting witnessed the unveiling of cutting-edge analytical techniques, offering enhanced sensitivity, selectivity, and accuracy for drug testing.

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.
