Hair Follicle Drug Testing - Lexington, MN

What it is, How it works

Hair analysis has emerged as a potent method to identify substance and alcohol intake. Hair offers a prolonged history of substance use by encasing biomarkers within the structure of the growing hair. When obtained near the scalp, hair can deliver a detection timeframe of up to three months for substances and alcohol. It is easy to collect, relatively hard to tamper with, and effortless to transport.

A 1.5-inch portion comprising roughly 200 strands (comparable to a #2 pencil in thickness) nearest to the scalp will provide 100mg of hair, which is the optimal sample for both screening and confirmation. For EtG tests, additional tests, and/or panels over ten, 150mg of the sample is advisable. It's recommended to measure the sample using a jeweler's scale. In the absence of scalp hair, a similar quantity of body hair can be used. Head hair specifically refers to scalp hair only, whereas body hair refers to all other types (like facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test assay comprises of four pivotal stages: Accessioning, Screening, Extraction, and Confirmation.

Accessioning entails the preliminary handling of a sample into the laboratory's system. This process includes confirming the proper sealing and shipment of the sample, allocating a random LAN (Laboratory Accessioning Number), and executing any further data entry not facilitated by an electronic chain of custody protocol.

Screening consists of an initial rapid assessment for substance abuse. While screening economically dismisses drug usage in most samples, a positive result must be validated to be admissible in legal proceedings. Any samples that yield a presumptive positive during Screening necessitate a follow-up confirmation.

If a specimen is presumed positive during the Screening phase, additional hair is taken from the initial sample and prepared for Extraction. During this phase, substances are extracted from the hair at significantly lower concentrations than alternative methods (e.g., urine or oral fluid), emphasizing the complexity of hair drug testing.

Confirmation of any positive screening result is undertaken through GC/MS, GC/MS/MS, or LC/MS/MS methods. All presumptive positive samples undergo washing prior to confirmation as required. The comprehensive laboratory process from Accessioning to Confirmation is evaluated according to both the CAP (College of American Pathologists) Hair designation and adherence to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can establish drug usage up to 90 days in contrast to the shorter detection time of urine tests.
• Minimal chance of tampering: It is notably difficult to falsify a hair drug test, ensuring accuracy of results.
• Offers historical patterns: It can illustrate a drug use pattern over an extended timeline, as opposed to only recent use.

Limitations:

• Lacks immediacy: It generally takes 5-7 days for substances to manifest in hair.
• Expense: Hair drug tests typically incur higher costs than alternative testing methods.
• Result variability: Factors such as hair color and personal differences in hair growth can influence drug metabolite concentrations in hair.

Note: Despite the frequent term "hair follicle tests," the analysis examines the hair strand, not the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

Hair follicle testing in Lexington, MN proves superior to traditional urine tests with its profound accuracy and extended detection window. Unlike urine tests, which might miss infrequent substance use, hair testing offers a more reliable assessment by examining months' worth of history. This gives a broader perspective on an individual's substance patterns and overall history.

Furthermore, hair tests mitigate the risk of tampering, demonstrating a consistency that urine tests can lack. They offer a non-invasive yet highly accurate procedure that remains unmatched in its ability to detect long-term substance use, thus serving effectively for stringent policies and regulations.

Extended Detection Window
