Hair Follicle Drug Testing - Lynd, MN

What it is, How it works

The use of hair testing has increasingly gained prominence as an effective method for identifying drug and alcohol consumption. Hair offers a prolonged overview of substance use by capturing biomarkers within its structural fibers as it grows. When hair is clipped near the scalp, it can potentially provide a detection period extending up to three months for alcohol and other substances. Collecting hair is straightforward, relatively hard to tamper with, and conveniently shippable.

An ideal sample for assessment and verification is a 1.5-inch segment containing around 200 hair strands (approximately the thickness of a #2 pencil) clipped closest to the scalp, yielding 100mg of hair. For EtG, supplementary analyses, and/or tests over 10 panels, 150mg is advisable. The specimen's weight should be measured on a jeweler's scale. If scalp hair is not present, an equivalent quantity of body hair can be used. References to head hair specifically imply scalp hair, while body hair denotes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result includes four key stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial handling of a sample within a lab's system. This step confirms the sample's proper sealing and shipment, assigns a unique LAN (Laboratory Accessioning Number), and completes any supplementary data entry not addressed by an electronic chain of custody mechanism.

Screening is an initial rapid assessment for substances of abuse. While it’s an economical method to eliminate drug usage in most specimens, any positive results require confirmation for legal admissibility in court. Presumed positive screenings necessitate additional verification.

Should a sample return a positive presumptive result during Screening, more hair from the initial batch is extracted for the Extraction stage. In this step, substances are extracted from hair at much lower concentrations than other means (such as urine or oral fluid), explaining why hair drug screening is a particularly challenging methodology.

Confirmation of positive screening outcomes is accomplished through GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive undergo washing in preparation for confirmation if required. The full laboratory procedure from Accessioning to Confirmation is scrutinized under both the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing is effective in identifying drug use for up to 90 days, whereas urine tests have a noticeably shorter window.
• Cheating mitigation: It's notably challenging to manipulate hair drug testing, ensuring higher accuracy in results.
• History of use: Hair testing can reflect a pattern of drug use over time, rather than just recent consumption.

Limitations:

• Unable to detect recent use: It takes roughly 5-7 days for drugs to appear detectable within hair samples.
• Expensive: Compared to other methods, hair drug testing generally incurs higher costs.
• Result variations: Variables like hair color and individual growth patterns can influence drug metabolite concentration in hair.

Note: Despite often being termed "hair follicle tests", this analysis examines the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Compared to traditional urine tests, hair follicle testing in Lynd, MN, provides superior detection accuracy and reliability. While urine tests are common, hair tests are favored for their extended detection period, accuracy in identifying substance usage, and bias-resistant results. The hair test accurately reflects prolonged substance habits, thus serving as a more comprehensive solution.

Extended Detection Window

With an extended detection window of up to 90 days, hair follicle testing offers a broader perspective on an individual’s substance use history in Lynd, MN. This lengthy detection period enables employers to gain a more comprehensive understanding of an applicant’s or employee’s potential drug habits, assuring them of informed hiring decisions and reinforcing their workplace policies.

Tamper-Resistant Testing Method

Hair follicle testing in Lynd, MN, is renowned for being a tamper-resistant method, substantially mitigating the risk of altering sample integrity.
