Hair Follicle Drug Testing - Hennepin, IL

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol use. Hair retains a comprehensive account of alcohol and drug consumption by embedding biomarkers within the strands as they grow. When taken near the scalp, hair offers a detection range of up to about 3 months for alcohol and drugs. The collection process is straightforward, making it hard to tamper with and simple to send off for testing.

A hair sample measuring 1.5 inches long, consisting of approximately 200 strands (similar in size to a #2 pencil) nearest the scalp, provides 100mg, which is the optimal quantity for both screening and confirmation. For tests like EtG or those exceeding 10 panels, 150mg of hair is advised. It's best to measure the sample with a jeweler’s scale. If scalp hair isn't accessible, equivalent body hair can be collected. In this context, head hair specifically means scalp hair, while body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory process for a drug test result includes four crucial steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails integrating a sample into the lab system initially. This encompasses ensuring the sample’s proper sealing and shipment, assigning a unique LAN (Laboratory Accessioning Number), and fulfilling any necessary data entry not provided by an electronic chain of custody system.

During Screening, there is a preliminary check for substance abuse. While Screening is a cost-efficient approach to eliminate drug usage in most samples, the positive findings require confirmation to be valid in court. Any sample flagged as presumptively positive during Screening necessitates further confirmation.

If a sample shows presumptive positivity in Screening, additional hair is extracted from the initial sample for Extraction. This step involves isolating drugs from hair at much lower concentrations than other methods (such as urine or oral fluid), making hair drug testing the most challenging method to conduct.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. Before confirmation, all samples with a presumptive positive result are washed as needed. The complete laboratory process from Accessioning to Confirmation is scrutinized under CAP (College of American Pathologists) Hair designation and it’s accredited to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection duration: Hair drug tests can identify drug use for a period of up to 90 days, unlike urine tests which cover a shorter span.
• Challenges to cheating: Cheating a hair drug test is highly challenging, thus increasing result reliability.
• Insights into past usage: It can reveal a drug use pattern over an extended period rather than just recent use.

Limitations:

• Inability to detect recent use: Drugs become detectable in hair approximately 5-7 days after use.
• Expense: Hair drug tests tend to be pricier than other drug testing techniques.
• Result variations: Variables such as hair color and individual growth trends can influence drug metabolite concentrations in hair.

Note: While commonly termed "hair follicle tests", the actual analysis is performed on the strand of hair, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

One major reason hair follicle testing surpasses urine assessments in Hennepin, IL, is its superior detection capability. Hair tests provide a broader and more reliable window of detection than traditional urine methods. Urine tests can miss long-term substance use, while hair analyses capture a complete picture, identifying drug use up to 90 days prior, making them ideal for rigorous screenings required by employers and legal entities.

Extended Detection Window

In Hennepin, IL, hair follicle testing stands out for its ability to trace drug use over an extended period, up to 90 days. This long detection window grants employers a clear and comprehensive view of an individual's substance history. It provides a detailed insight that aids in making more informed employment decisions, supporting a safer work environment by revealing patterns that may not be detectable in shorter-term tests.

Tamper-Resistant Testing Method

Hair follicle tests are a tamper-resistant method used in Hennepin, IL, significantly reducing the risk of sample tampering or adulteration that might occur in other testing types. By analyzing a non-intrusive component, like hair, the integrity of the sample is maintained, ensuring the results are genuine and reliable. This strengthens the credibility of the test outcomes, offering assurance to employers and regulatory bodies alike.

Convenient Nationwide Locations
