Hair Follicle Drug Testing - Greenfield, MN

What it is, How it works

Hair analysis is widely regarded as an effective means of identifying drug and alcohol consumption. Hair strands capture biomarkers within their fibers as they grow, providing a long-term record of substance use. When collected near the scalp, hair samples can reveal alcohol and drug use for up to about three months. Sampling is straightforward, challenging to tamper with, and convenient to transport.

A sample that measures 1.5 inches and includes roughly 200 hair strands (approximately the size of a #2 pencil) nearest to the scalp yields 100mg of hair, which is optimal for testing and verification. For EtG, additional substances, and/or assessments beyond 10-panel tests, a sample of 150mg is advised. Using a jeweler's scale to weigh the sample is recommended. If scalp hair isn't available, an equivalent quantity of body hair can be obtained. "Head hair" refers specifically to scalp hair. "Body hair" encompasses all other types of hair (facial, axillary, etc.).

Process Overview

There are four primary phases in the lab processing of a drug test result: Accessioning, Screening, Extraction, and Confirmation.

Accessioning includes the initial entry of a sample into a lab's system. This process verifies proper sealing and shipment of the sample, assigns a unique LAN (Laboratory Accessioning Number), and completes any extra data entry not handled by an electronic chain of custody system.

Screening consists of a fast preliminary check for drug presence. While Screening is an efficient way to dismiss drug use in most samples, a positive result must be confirmed to be legally valid. Any samples that test positive during Screening require a follow-up confirmation.

Should a sample test positive in the Screening phase, additional hair is taken from the original sample and prepared for Extraction. Drugs are isolated from hair at a much lower concentration than in other methods (e.g., urine or oral fluid), making hair drug analysis one of the most complex techniques to conduct.

Confirmation of a positive screen is performed using GC/MS, GC/MS/MS, or LC/MS/MS methods. All samples that screen positive are cleansed before confirmation if necessary. The complete lab process, from Accessioning to Confirmation, is evaluated under both CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug testing can identify drug use for as long as 90 days, unlike urine tests which detect recent use.
• Hard to manipulate: Cheating a hair drug test is quite difficult, thus enhancing result accuracy.
• Tracks usage pattern: It reveals a timeline of drug use, beyond just recent consumption.

Limitations:

• Misses recent use: Detection in hair takes about 5-7 days after drug use begins.
• Expense: Hair drug tests typically cost more than other testing techniques.
• Result variability: Hair color and growth differences can influence drug metabolite concentrations in hair.

Note: Although frequently called "hair follicle tests," the analysis actually examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Greenfield, MN, is superior to traditional urine tests due to its longer detection period and heightened accuracy. Unlike urine tests, which may only detect recent drug use, hair tests offer insight into substance habits over the past 90 days, making it indispensable for comprehensive evaluations.

The reliability of hair follicle testing is unmatched. While urine tests are prone to adulteration and substitution, hair tests are resistant to these issues, ensuring organizations can fully trust their results. This makes it a more effective tool for enforcing zero-tolerance policies and carrying out due diligence.

Extended Detection Window
