Hair Follicle Drug Testing - Columbia, MS

What it is, How it works

Hair testing is increasingly recognized as an effective method for identifying drug and alcohol consumption. Hair offers a long-term record of substance use by capturing biomarkers within the strands as they grow. When cut close to the skin, hair provides a detection period of up to roughly three months for alcohol and drugs. It's easy to collect, hard to tamper with, and simple to transport.

A 1.5-inch section of roughly 200 hairs (around the thickness of a #2 pencil) nearest to the scalp yields 100mg of hair—the optimal sample size for assessment and confirmation. For tests involving EtG or those exceeding ten panels, a 150mg sample is advised. It's best to measure the sample using a jeweler's scale. If head hair is not available, an equivalent amount of body hair can be used. When referencing head hair, it pertains specifically to scalp hair, while body hair includes all other types (facial, underarm, etc.).

Process Overview

The primary phases in processing a laboratory drug test result are Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves initially processing a sample into the lab’s database. This step ensures the sample was properly sealed and transported, assigns it a random Laboratory Accessioning Number (LAN), and completes any supplementary data entry absent from an electronic chain of custody system.

Screening entails a preliminary rapid test for substances of abuse. Although Screening is a cost-efficient method to rule out drug use in most samples, any positive result must be confirmed for court acceptance. Samples yielding a presumptive positive in Screening need further affirmation.

If Screening yields a presumptive positive result, additional hair is retrieved from the original sample for the Extraction step. During this phase, drugs are extracted from hair at concentrations much lower than in other methods, such as urine or oral fluid, making hair testing particularly challenging.

Positive results in Screening undergo Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All suspected positive samples are cleansed prior to confirmation as necessary. The entire lab process from Accessioning to Confirmation is inspected according to the CAP (College of American Pathologists) Hair criteria and the accreditation under ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, whereas urine tests have a shorter detection window.
• Hard to deceive: Hair drug tests are difficult to falsify, offering more accurate results.
• Chronicles usage history: It reveals drug usage patterns over time, not solely recent use.

Limitations:

• Incapable of identifying recent use: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug tests generally cost more than other testing techniques.
• Result variability: Factors like hair color and individual hair growth differences can influence drug metabolite concentrations in hair.

Note: Though commonly termed "hair follicle tests," these tests analyze the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Why does hair follicle testing outshine urine tests in Columbia, MS? Simply put, it offers superior detection accuracy. Unlike traditional urine assessments, hair tests capture a broader drug use history, making them far more reliable for long-term detection.
