Hair Follicle Drug Testing - Oneida, IA

What it is, How it works

Hair testing is increasingly being recognized as an effective means for detecting drug and alcohol consumption. Hair retains a long-term record of alcohol and drugs by embedding biomarkers in the fibers of the developing hair strand. When hair is collected near the scalp, it can offer up to a 3-month detection period for alcohol and other drugs. Hair is easy to collect, challenging to tamper with, and convenient to transport.

A 1.5-inch sample consisting of approximately 200 hair strands (about the width of a #2 pencil) closest to the scalp will yield 100mg of hair, which is the optimal amount for screening and confirmation. For EtG, add-ons, or tests exceeding 10 panels, 150mg of the specimen is advised. We suggest using a jeweler’s scale to measure the specimen. If scalp hair isn't obtainable, an equivalent amount of body hair can be collected. When discussing head hair, we specifically mean scalp hair. Body hair pertains to all other types (facial, axillary, etc.).

Process Overview

The laboratory process for a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the initial processing of a sample into a laboratory system. It includes confirming that the sample was properly sealed and shipped, assigning a random LAN (Laboratory Accessioning Number), and filling in any additional data not provided by an electronic chain of custody system.

Screening is a preliminary quick check for drugs of abuse. While Screening is a cost-effective method for ruling out drug usage in most samples, a positive screen must be confirmed for it to be admissible in court. Any samples that test presumptively positive in Screening require further confirmation.

If a sample shows a presumptive positive during Screening, additional hair is taken from the initial specimen for the Extraction phase. In this process, drugs are extracted from hair at significantly lower concentrations than in other methodologies (e.g., urine or oral fluid), which is why hair drug screening is the most challenging methodology to administer.

Confirmation of any positive screening results is carried out via GC/MS, GC/MS/MS, or LC/MS/MS. All samples that are presumptively positive are washed before confirmation as necessary. The full laboratory process from Accessioning to Confirmation is reviewed under both the CAP (College of American Pathologists) Hair designation and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can identify drug use for as long as 90 days, unlike urine tests which have a shorter detection period.
• Hard to evade: It's very challenging to manipulate a hair drug test, leading to more accurate results.
• Produces historical information: It can display a pattern of drug use over time, not merely recent consumption.

Limitations:

• Inability to detect recent use: It takes roughly 5-7 days for drugs to become detectable in hair.
• Expense: Hair drug tests are typically more costly than other drug testing techniques.
• Result variability: Factors such as hair color and individual growth rate can influence drug metabolite concentration in hair.

Note: Although often termed as "hair follicle tests", the test actually examines the hair strand and not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Oneida, IA, hair follicle testing offers several advantages over traditional urine testing. The enhanced detection accuracy of hair analysis means it can reliably indicate substance use over a more extended period, which urine tests might miss.

One major benefit of hair tests is their superior reliability. They provide a comprehensive understanding of an individual's drug history, negating attempts at deception that urine tests are more susceptible to.

Extended Detection Window

In Oneida, IA, the extended detection window of hair follicle testing offers a comprehensive view of an individual’s substance use, covering up to 90 days. This time frame is advantageous for employers aiming to understand the long-term behaviors of applicants or employees.

The long detection span makes hair testing ideal for providing a thorough assessment of drug use, surpassing other methods in its ability to reveal an extensive substance history effectively.
