Hair Follicle Drug Testing - Holt, AL

What it is, How it works

Hair analysis is now viewed as a potent method for identifying drug and alcohol consumption. It provides a long-term record of substance use by embedding biomarkers in the strands of hair as it grows. When sourced near the scalp, hair can offer an approximate three-month detection period for various substances. It is easy to collect, relatively hard to tamper with, and convenient for shipping.

A 1.5-inch segment consisting of around 200 hair strands (equivalent to a #2 pencil) near the scalp yields 100mg, the optimal amount for screening and verification. For EtG tests, add-ons, or evaluations exceeding 10 panels, a 150mg sample is suggested. It's advisable to measure the sample using a jeweler's scale. Should scalp hair be absent, a comparable measure of body hair is acceptable. Reference to head hair pertains exclusively to scalp hair. Body hair encompasses other types (facial, axillary, etc.).

Process Overview

The key stages in the laboratory analysis of a drug test sample involve Accessioning, Screening, Extraction, and Confirmation.

Accessioning is dedicated to the initial handling of a specimen within a lab's system, ensuring the sample’s proper sealing and delivery, assigning a random LAN (Laboratory Accessioning Number), and finalizing data entry that isn't covered by an electronic chain of custody system.

Screening acts as an essential preliminary examination for substance abuse. It’s an economical approach to eliminate drug usage across most samples; however, a positive screen necessitates confirmation to be deemed valid in legal settings. Any samples preliminarily positive in Screening necessitate further confirmation.

Should a sample appear presumptively positive during the Screening phase, additional hair is extracted from the original sample to prepare for Extraction. This phase involves removing drugs from hair at much lower concentrations than other techniques (e.g., urine or mouth swab), which is why hair screening is among the most challenging to perform.

Positive screening results are confirmed using GC/MS, GC/MS/MS, or LC/MS/MS. All samples marked presumptively positive undergo washing before confirmation as needed. The entire lab workflow, from Accessioning to Confirmation, undergoes review under both the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair testing can identify drug use for up to 90 days, unlike urine tests which have a more limited detection period.
• Hard to manipulate: Cheating a hair drug test is very challenging, thus results are typically more reliable.
• Shows usage trends: It offers insight into substance use patterns over time, not solely recent consumption.

Limitations:

• Limited to non-recent use: Drugs need around 5-7 days to become traceable in hair.
• Higher cost: Hair drug testing is often pricier compared to other methods.
• Result variability: Variables like hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Commonly known as "hair follicle tests", these tests analyze the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

The choice between hair follicle and urine testing in Holt, AL highlights many benefits. Hair tests offer superior detection accuracy and reliability, capable of identifying substance use patterns over a more extended period. Unlike urine tests, which primarily detect recent drug use, hair testing provides a broader view of potential substance abuse history.

Extended Detection Window

A significant advantage of hair follicle testing in Holt, AL is the extended detection window. It tracks drug use over as many as 90 days, giving employers a clearer understanding of an individual's substance use history. This extended tracking surpasses what urine tests offer, which mainly cover short-term use, thus providing a thorough examination of both current and past substance use, ensuring a fuller overview for HR and compliance purposes.

Tamper-Resistant Testing Method

With tamper-resistant attributes, hair follicle tests significantly minimize the chances of sample adulteration in Holt, AL. The integrity of hair testing stands against cheating attempts, presenting unquestionable and reliable results. Unlike urine tests, prone to manipulation, hair samples are collected and analyzed under conditions that ensure validity and accuracy, putting any concerns about result integrity at ease.
