Accredited Drug Testing offers comprehensive hair follicle drug testing services in Clarksville, Missouri. If hair drug or alcohol testing is necessary, Accredited Drug Testing is a specialist in this area with centers nationwide. Most cases require 1.5 to 2 inches of hair, either from the head or body. Hair tests can also be tailored for drugs, alcohol/ETG, and other specific options.

Recently, the trend in drug testing has increasingly favored hair follicle tests. Employers, courts, and substance abuse experts opt for hair tests over standard urine tests. Hair follicle tests adhere to zero-tolerance policies, useful for employers, courts, and probationers. A significant advantage is its extended detection period for substance use, up to 90 days, with observed collection maintaining accuracy. Nevertheless, urine tests remain ideal for detecting recent drug use within 5 days.

What it is, How it works

Hair analysis is now recognized as an excellent method for detecting substance and alcohol consumption. Hair holds a prolonged record of these substances as it captures biochemical indicators within the threads of the maturing hair shaft. When clipped close to the scalp, it can indicate substance presence for a period lasting up to three months. This method is straightforward in collection, less prone to tampering, and convenient to transport.

A 1.5-inch segment comprising around 200 hair strands (similar in size to a #2 pencil) near the scalp provides 100mg of hair, which is ideal for both screening and verification. For EtG, add-ons, or screenings exceeding 10 panels, 150mg is preferred. It's advised to measure the sample with a jeweler's scale. Should scalp hair be inaccessible, an equivalent mass of body hair can be utilized. In this context, head hair refers specifically to scalp hair. Body hair includes all other types (facial, axillary, etc.).

Procedure Synopsis

The laboratory processing path for a drug screening comprises four fundamental steps: Accessioning, Screening, Extraction, and Validation.

Accessioning entails the initial incorporation of a sample into a lab's protocol. This process includes confirming the sample was sealed and dispatched correctly, generating a random LAN (Laboratory Accessioning Number), and carrying out any extra data processing not managed by an electronic chain-of-custody system.

Screening involves an initial rapid assessment for narcotics use. Though Screening is a cost-efficient approach to exclude substance usage on most specimens, a positive result requires confirmation to be permissible in court. Samples that are tentatively positive in Screening need secondary verification.

In scenarios where a sample is tentatively positive at the Screening phase, an additional amount of hair is gathered from the primary specimen and readied for Extraction. During Extraction, substances are isolated from hair at significantly lower averages than in other procedures (e.g., urine or oral samples), establishing hair analysis as the most intricate method to conduct.

Verification of any positive results from screening is executed through GC/MS, GC/MS/MS, or LC/MS/MS. All potentially positive samples undergo washing before verification as required. The complete laboratory process from Accessioning through to Validation is scrutinized under the CAP (College of American Pathologists) Hair classification and the certification to ISO/IEC 17025 standards.

Benefits of hair drug analysis:

  • Prolonged detection period: Hair analysis can identify substance use up to 90 days, in contrast to urine tests with a shorter detection period.
  • Hard to falsify: It is exceptionally challenging to manipulate a hair drug test, enhancing result reliability.
  • Offers historical insight: It can reveal a pattern of substance consumption over time, rather than just recent use.

Constraints:

  • Incapable of recent consumption detection: It generally takes about 5-7 days for substances to become traceable in hair.
  • Expense: Hair drug screenings are usually pricier compared to other testing techniques.
  • Result variability: Factors such as hair pigmentation and individual hair growth differences can influence drug metabolite concentrations within the hair.

Note: Although commonly referred to as "hair follicle tests," the analysis focuses on the hair strand rather than 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.
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.
