In Greendale, MO, Accredited Drug Testing offers comprehensive hair follicle drug testing solutions. Whether you require a drug or alcohol test, our expertise in hair testing ensures that you receive reliable results at any of our nationwide centers. To perform a hair test, typically 1.5 to 2 inches of hair from the scalp or body is required. Hair testing includes options for drugs, alcohol/ETG, and other customized assessments.

Hair follicle testing has become a preferred method for drug screening in recent times. An increasing number of employers, judicial bodies, and substance abuse professionals now opt for hair tests over the traditional urine tests. Employers with strict no-drug policies, as well as courts and individuals on probation, utilize these tests. A key advantage is their extended detection window, reaching up to 90 days, almost eliminating the potential for tampering. However, for detecting recent drug use within five days, urine tests remain the most reliable.

What it is, How it works

Hair analysis has gained recognition as an effective method for detecting drug and alcohol consumption. It offers a comprehensive history of alcohol and drug exposure by embedding biomarkers within the hair strand as it grows. By collecting hair near the scalp, a timeframe of roughly three months can be analyzed for drug and alcohol presence. The collection process is straightforward, the risk of tampering is minimal, and transport is hassle-free.

A sample measuring 1.5 inches comprising approximately 200 hair strands (comparable to the width of a #2 pencil) taken from the scalp provides a 100mg sample, ideal for thorough screening and verification. For EtG tests or analyses exceeding 10 panels, a 150mg sample is advisable. Utilizing a jeweler’s scale to measure the sample is recommended. In instances where scalp hair is inaccessible, an equivalent volume of body hair may be utilized. When addressing head hair, we specifically mean scalp hair. Body hair encompasses all other types (such as facial and axillary).

Process Overview

The four core procedures in laboratory processing of a drug test outcome include Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample within a lab's framework. This covers confirming that the sample was properly sealed and transported, assigning a unique LAN (Laboratory Accessioning Number), and completing any additional information entry absent from an electronic chain of custody system.

Screening is a preliminary assessment to identify potential drug misuse. Although Screening is a cost-efficient approach to exclude drug use for the majority of cases, any positive results need further verification to be considered valid in legal contexts. Samples flagged as presumptively positive during Screening necessitate a subsequent confirmation step.

If a presumptive positive is identified during the Screening phase, additional hair is extracted from the original sample for Extraction. Here, drugs are isolated from hair at levels significantly lower compared to other techniques (e.g., urine or saliva), which makes hair drug analysis the most challenging process to conduct.

Positive screening outcomes are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS methods. Prior to confirmation, all samples presumed positive are cleaned as necessary. The complete lab procedure, from Accessioning to Confirmation, is scrutinized under both the CAP (College of American Pathologists) Hair classification and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

  • Extended detection duration: Hair drug assessments can identify drug consumption for as long as 90 days, in contrast to urine assessments which have a reduced detection duration.
  • Challenging to falsify: Hair drug assessments are difficult to manipulate, enhancing result fidelity.
  • Offers historical insight: It reveals patterns of drug use over time, not merely recent use.

Limitations:

  • Unable to identify recent consumption: Detecting drugs in hair takes around 5-7 days.
  • Expenses: Hair drug assessments typically cost more than alternative drug testing techniques.
  • Variation in outcomes: Variables such as hair hue and individual disparities in hair growth can influence drug metabolite concentration in hair.

Note: Commonly labeled as "hair follicle tests", the examination focuses on the hair strand, not the root beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why Hair Follicle Testing Beats Urine Testing in Greendale, MO
Hair follicle testing outshines traditional urine testing by offering superior detection accuracy. While urine tests are effective for recent drug use, hair tests detect substances over an extensive period, making them more reliable. Additionally, hair tests have a longer detection window, capturing drug use that may be missed by urine tests.

In Greendale, the adoption of hair testing is increasing for its reliability in revealing a comprehensive picture of an individual's drug use history. This method is nearly tamper-proof, reducing the possibility of sample adulteration. Consequently, employers rely on hair testing to maintain workplace integrity and compliance, ensuring the safety and productivity of their teams.

Extended Detection Window

Extended Detection Window in Greendale, MO
One of the significant advantages of hair follicle testing is its extended detection window of up to 90 days. This provides employers with an expansive overview of an applicant's substance use history, crucial for decision-making. While urine tests offer a brief detection period, hair tests ensure no previous substance use is overlooked.

Employers in Greendale benefit from this in-depth analysis, as it facilitates the assessment of long-term drug usage trends rather than short-term occurrences. By implementing hair testing, companies are equipped to evaluate potential hires thoroughly, thus fostering a more secure and productive workplace environment.
