Hair Follicle Drug Testing - Kendrick, MS

What it is, How it works

Hair testing has emerged as a significant means for identifying drug and alcohol consumption. Hair captures the biomarkers of alcohol and drugs within the strands as they grow, offering a prolonged historical insight. When gathered near the scalp, it can provide an approximate 3-month detection timeline for these substances. Hair is easy to gather, somewhat challenging to tamper with, and simple to transport.

A 1.5-inch segment of around 200 strands of hair (comparable in size to a #2 pencil) taken from the scalp will yield 100mg, which serves as the preferred sample for screening and validation. For EtG, supplements, and tests exceeding 10 panels, a 150mg sample is advisable. We suggest weighing the sample using a jeweler's scale. If scalp hair isn't available, a similar volume of body hair may be used. By head hair, we specifically mean scalp hair, whereas body hair encompasses all other types (like facial, axillary, etc.).

Process Overview

The drug test result processing within a laboratory involves four core steps: Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample first enters the lab's system. This process includes making sure the sample was secured and transported correctly, allocating a random LAN (Laboratory Accessioning Number), and finalizing any extra data entry not facilitated by an electronic chain of custody system.

Screening offers an initial rapid assessment for substances of abuse. Though Screening provides an economical method to rule out drug use in most samples, any positive screen must be confirmed for legal admissibility. Presumptive positive samples in Screening warrant further confirmation.

Should a sample yield a presumptive positive during Screening, additional hair from the initial sample is utilized for Extraction. In this phase, drug extraction from hair occurs at a substantially lower concentration than in other methods (such as urine or oral fluid), rendering hair drug screening the most intricate method to execute.

The Confirmation process for any positive screen involves using GC/MS, GC/MS/MS, or LC/MS/MS. All presumptive positives are cleaned before Confirmation if necessary. The continuum from Accessioning to Confirmation is assessed under both the CAP (College of American Pathologists) Hair standards and the accreditation for ISO / IEC 17025.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can trace drug use up to 90 days, unlike urine tests with a more limited detection range.
• Tough to manipulate: Cheating a hair drug test is very hard, thereby enhancing result precision.
• Historical usage insight: It provides an overview of drug consumption trends over time, not merely recent usage.

Limitations:

• Incapable of detecting recent consumption: Drugs become detectable in hair only after about 5-7 days.
• Expense: Hair drug testing typically incurs more costs compared to other drug testing forms.
• Result variability: Elements like hair color and individual differences in hair growth may influence drug metabolite concentrations in hair.

Note: Referred to frequently as "hair follicle tests", the testing actually examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing outshines urine tests in Kendrick, MS, by delivering superior accuracy and reliability. Hair testing provides a broader detection scope, capturing a more extended history of substance use. Unlike urine tests, which are limited by their shorter detection period, hair tests can detect drugs up to 90 days. This extended window provides a clear and comprehensive assessment of an individual's substance use, reducing the chance of passing unnoticed drug usage.

Extended Detection Window

Drugs remain detectable through hair follicle testing for an impressive duration, up to 90 days in Kendrick, MS. This extended detection period grants employers a well-rounded view of an applicant's or employee's drug use history, unlike other tests that offer only short-term insights. By testing the strands of hair, businesses are armed with a more comprehensive understanding of an individual's substance usage, enhancing their ability to make informed staffing decisions.
