Hair Follicle Drug Testing - Cold Spring, WI

What it is, How it works

Hair analysis has gained recognition as an effective method for identifying drug and alcohol consumption. The hair encapsulates a prolonged record of alcohol and other drugs by embedding biomarkers within the strands of the expanding hair. When obtained near the scalp, hair can offer an approximate 90-day detection period for alcohol and other drugs. The process of collecting hair is straightforward, relatively resistant to tampering, and easy to transport.

A 1.5-inch section comprising roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal sample for both screening and verification. For EtG, additional tests, and/or panels exceeding 10, a recommendation of 150mg of the sample is advised. We suggest using a jeweler’s scale for weighing the specimen. If scalp hair cannot be obtained, a similar quantity of body hair may be used. References to head hair specifically mean scalp hair. Body hair encompasses all other types (facial, axillary, etc.).

Process Overview

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

Accessioning entails initially processing a sample within a laboratory’s framework. This step includes confirming that the sample was correctly sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and fulfilling any supplementary data entry not covered by an electronic chain of custody system.

Screening is a preliminary rapid assessment for detecting drug abuse. While it is an economical method to exclude drug usage for most samples, a positive screening must be verified to be valid in court. Samples that yield a presumptive positive during Screening require additional confirmation.

When a sample tests positive at the Screening stage, more hair is extracted from the original specimen and prepared for Extraction. During this phase, drugs are extracted from hair at significantly lower concentrations than in other methods (such as urine or oral fluid), making hair drug testing the most challenging methodology.

Confirmation of any positive screening is achieved via GC/MS, GC/MS/MS or LC/MS/MS techniques. All samples with presumptive positive results undergo washing before confirmation, as required. The complete laboratory process, from Accessioning to Confirmation, is evaluated according to both the CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for up to 90 days, in contrast to urine tests that have a shorter detection period.
• Challenging to falsify: Cheating a hair drug test is extremely difficult, resulting in more reliable outcomes.
• Provides usage pattern: It offers insights into a pattern of drug use over time, unlike tests that only detect recent use.

Limitations:

• Incapable of detecting recent use: Drugs take about 5-7 days to become detectable in hair.
• Expense: Hair drug tests are typically costlier than alternative drug testing approaches.
• Result variability: Factors like hair color and individual differences in hair growth can impact drug metabolite concentration in hair.

Note: While often referred to as "hair follicle tests", the examination targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing stands superior in Cold Spring, WI, due to its enhanced accuracy and reliability over traditional urine tests. Unlike urine analysis, which captures drug use within days, hair testing spans a multi-month period, revealing long-term patterns.

The reliability of hair testing ensures a broader detection spectrum, providing insights beyond recent drug consumption. This accuracy supports businesses enforcing zero-tolerance policies and complying with legal standards effectively.

Extended Detection Window

Hair follicle testing in Cold Spring, WI, offers a remarkable detection window extending up to 90 days. This prolonged period allows employers to gain a complete understanding of an individual’s drug use history, assisting in making informed decisions.

Compared to shorter detection periods of other drug tests, hair analysis provides a detailed analysis, revealing any repetitive substance abuse patterns. This extended look makes it indispensable for assessing long-term drug habits.

Tamper-Resistant Testing Method

The tamper-resistant nature of hair follicle tests in Cold Spring, WI, ensures the integrity of every result. Unlike urine tests, hair samples cannot be easily altered or diluted, safeguarding against any attempts to falsify results.

Through observed collection and resistant sample types, it becomes almost impossible to cheat the system. This reliability makes hair testing a trustworthy option for consistent, authentic drug assessment outcomes.
