Hair Follicle Drug Testing - Lake Itasca, MN

What it is, How it works

Hair analysis has emerged as a significant method for detecting substances. Hair offers a comprehensive record of substance usage by embedding markers within the fibers of the hair as it grows. When taken from near the scalp, it can yield up to a three-month window of detection for various substances. Hair is straightforward to obtain, relatively hard to tamper with, and convenient to dispatch.

A sample measuring 1.5 inches, comprising roughly 200 hair strands (comparable to a #2 pencil in thickness) near the scalp provides 100mg of hair, which is perfect for examination and verification. For EtG, additional tests, and/or panels exceeding 10, 150mg of hair is advisable. We suggest using a jeweler’s scale to weigh the sample. If scalp hair isn't present, the same amount of body hair may be used. By head hair, we specifically refer to scalp hair. Body hair encompasses other types such as facial and axillary hair.

Process Overview

The key stages in a lab processing a drug test result include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the initial integration of a sample into a lab’s records. It confirms that the sample was properly sealed and dispatched, assigns a unique LAN (Laboratory Accessioning Number), and inputs any extra data not captured by an electronic chain of custody system.

Screening is a preliminary check for illicit substances. While it's a cost-efficient method to dismiss most drug usage, a positive screen must be further verified for legal acceptance. Any samples considered positive during Screening necessitate additional Confirmation.

If Screening indicates a presumptive positive, further hair is drawn from the original sample and readied for Extraction. Here, substances are extracted at significantly lower concentrations than in other methods (like urine or oral fluid), highlighting why hair drug testing is particularly challenging.

Confirmation of any positive screen occurs via GC/MS, GC/MS/MS, or LC/MS/MS. Any presumptive positive samples are cleansed before confirmation if necessary. The comprehensive laboratory sequence from Accessioning to Confirmation is examined under the guidelines of CAP (College of American Pathologists) Hair designation and recognized by ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair tests can identify drug use spanning up to 90 days, unlike urine tests which have a reduced detection period.
• Challenge to deceive: Cheating a hair drug test is very challenging, thus increasing result accuracy.
• Reveals historical usage: It illustrates a pattern of substance usage over time, rather than merely recent usage.

Limitations:

• Inability to detect recent usage: It requires about 5-7 days for substances to show in hair.
• Expense: Hair drug testing is usually more costly compared to other testing methods.
• Result variability: Elements like hair color and individual differences in hair growth can impact drug metabolite levels in hair.

Note: While commonly called "hair follicle tests", the evaluation targets the hair strand rather than the follicle itself under the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lake Itasca, MN, the preference for hair follicle testing over urine tests is supported by several advantages. Hair tests provide a longer detection period, capturing drug use that occurred several months prior. This is particularly beneficial for employers seeking detailed substance histories.
