Hair Drug Testing Locations - Pease, MN

What it is, How it works

Hair testing is recognized as a formidable method for identifying drug and alcohol consumption. Hair captures long-term evidence of alcohol and drug presence by embedding biomarkers within its growing strands. When harvested near the scalp, it allows up to nearly a 3-month detection timeframe for substances. The process of collection is straightforward; tampering is quite challenging, and shipping is hassle-free.

A 1.5-inch snippet of approximately 200 hair strands (akin to the thickness of a #2 pencil) nearest to the scalp yields 100mg, the optimal sample size for testing and verification. For EtG, supplementary tests, or beyond a 10-panel test, 150mg of hair is advised. Utilizing a jeweler’s scale for weighing is suggested. If scalp hair is scarce, a similar measure of body hair can be used. When discussing head hair, it specifically pertains to scalp hair. Body hair encompasses all other types of hair (facial, axillary, etc.).

Process Overview

There are four primary phases in processing a drug test outcome: Accessioning, Screening, Extraction, and Confirmation.

Accessioning involves the primary integration of a sample into the laboratory’s procedures. This phase checks that the sample was correctly sealed and transported, assigns a random LAN (Laboratory Accessioning Number), and fulfills any extra data logging not included in an electronic chain of custody system.

Screening entails an initial rapid evaluation for substances of abuse. Screening offers an economical method to exclude drug use in most samples, though a positive result must be validated for courtroom acceptance. Samples showing a preliminary positive result in Screening necessitate additional confirmation.

For samples with a preliminary positive in the Screening phase, additional hair is retrieved from the original sample for Extraction. Here, drugs are isolated from hair at significantly lower concentrations than other methods (e.g., urine or oral fluid), making hair drug analysis the most demanding to execute.

Positive screening results are verified using GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially positive are cleaned before confirmation if needed. The full laboratory workflow from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair classification and ISO / IEC 17025 accreditation.

Advantages of hair drug testing:

• Extended detection window: Hair drug tests can identify drug use up to 90 days, while urine tests feature a briefer detection span.
• Hard to falsify: Cheating a hair drug test is exceedingly difficult, providing more dependable results.
• Yields historical patterns: It tracks a timeline of drug use rather than simply recent use.

Limitations:

• Delayed recent use detection: Drugs become noticeable in hair only after roughly 5-7 days.
• Expense: Hair drug testing is typically pricier than other methods.
• Result variability: Elements like hair color and individual hair growth can influence drug metabolites concentration in hair.

Note: Commonly misnamed as "hair follicle tests", this test actually examines the hair strand, not the follicle beneath the scalp.
