Hair Follicle Drug Testing - Olivet, TN

What it is, How it works

Hair examination has gained recognition as an effective means for identifying drug and alcohol consumption. Hair retains a prolonged history of alcohol and drug exposure by securing biomarkers within the fibers of the extending hair strand. When obtained from the area nearest to the scalp, hair may offer up to a nearly three-month period of detection for alcohol and different drugs. Hair collection is straightforward, somewhat challenging to tamper with, and convenient to send.

A 1.5-inch portion consisting of around 200 hair strands (comparable to the size of a #2 pencil) nearest to the scalp will yield 100mg of hair, which is the optimal amount for screening and verification. For EtG, supplemental tests, and/or screenings beyond 10 panels, 150mg of the sample is advised. It’s suggested to measure the sample using a jeweler's scale. Should scalp hair be inaccessible, a comparable amount of body hair can be obtained. When mentioning head hair, it strictly refers to scalp hair. Body hair encompasses all other hair categories (facial, axillary, etc.).

Process Overview

The process for a drug test result consists of four key phases: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary entry of a sample into the lab’s system. This process ensures the sample was properly sealed and dispatched, assigns a random LAN (Laboratory Accessioning Number), and completes any remaining data entry not covered by an electronic chain of custody system.

Screening is the preliminary evaluation for drugs of abuse. Though Screening is a cost-effective method for excluding drug use in the majority of specimens, a positive outcome requires confirmation for court admissibility. Any samples with presumptive positive results in Screening necessitate additional confirmation.

When a sample is deemed presumptively positive during Screening, more hair is drawn from the original sample and readied for Extraction. In this step, drugs are extracted from hair at significantly lower concentrations compared to other methods (like urine or oral fluid), explaining why hair drug screening is the most challenging method to execute.

Confirmation for any positive screening result is carried out using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed prior to confirmation as required. The entire laboratory sequence from Accessioning to Confirmation is scrutinized under both CAP (College of American Pathologists) Hair designation and accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug evaluations can perceive drug use up to 90 days, unlike urine tests which offer a shorter detection span.
• Cheating is challenging: It is extremely hard to manipulate a hair drug test, enhancing result accuracy.
• Offers historical insight: It provides a record of drug usage over a time frame, not merely recent consumption.

Limitations:

• Incapable of spotting immediate use: Drugs need approximately 5-7 days to be noticeable in hair.
• Expense: Hair drug evaluations tend to be more costly than other drug testing approaches.
• Result variability: Elements such as hair coloration and individual growth differences can influence drug metabolite levels in hair.

Note: Although often called "hair follicle tests," the analysis is conducted on the hair strand and not the scalp-embedded follicle.

Why Hair Follicle Testing Beats Urine Testing

In Olivet, TN, hair follicle testing demonstrates clear advantages over urine tests. The extended detection period and difficulty in manipulation makes hair testing more trustworthy. While urine tests detect recent usage, hair tests offer a broader timeline, giving a clear view of an individual’s substance history.
