Hair Follicle Drug Testing - Norshor Junction, MN

What it is, How it works

Hair testing has emerged as an effective means for identifying drug and alcohol consumption. By capturing biomarkers in the fibers of the hair strand, hair offers a history of alcohol and other substances. When collected near the scalp, hair can reveal a detection period for drugs and alcohol extending up to roughly 90 days. Hair collection is straightforward, relatively resistant to tampering, and simple to transport.

A 1.5-inch segment of approximately 200 hair strands (akin to the diameter of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the preferred sample amount for both screening and verification. For tests including EtG, supplements, and/or over 10 panels, a sample amount of 150mg is advisable. Using a jeweler's scale to measure the specimen's weight is suggested. If scalp hair cannot be obtained, an equivalent portion of body hair is acceptable. When discussing head hair, this refers solely to scalp hair. All other hair types (like facial, axillary, etc.) are categorized as body hair.

Process Overview

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

Accessioning pertains to the initial integration of a sample into a lab's system. This step ensures the sample was correctly sealed and sent, assigns a unique LAN (Laboratory Accessioning Number), and finalizes any supplementary data entry not covered by an electronic chain of custody system.

Screening offers an initial rapid assessment for substance abuse. While Screening is an economical method to negate drug use in most samples, court-admissible positive screenings necessitate confirmation. Samples with presumed positivity in Screening require further confirmation.

In cases where the sample shows presumed positivity during Screening, additional hair is drawn from the original sample and set for Extraction. At this stage, drugs are extracted from hair at a significantly reduced concentration compared to other methods (such as urine or oral fluid), which makes hair drug screening one of the most challenging methodologies.

Every positive screening result undergoes Confirmation using GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed as necessary before confirmation. The entire lab process from Accessioning to Confirmation is scrutinized under the CAP (College of American Pathologists) Hair criteria and the accreditation to ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection range: Hair drug tests can trace drug usage up to 90 days, in contrast to urine tests, which have a more limited detection range.
• Hard to deceive: Cheating a hair drug test is exceedingly difficult, increasing result accuracy.
• Offers historical insights: It reveals patterns of drug use over time, not merely recent use.

Limitations:

• Not suitable for detecting recent use: It requires about 5-7 days for drugs to become traceable in hair.
• Expense: Hair drug tests generally cost more than other testing methods.
• Result variability: Factors such as hair color and individual differences in hair growth can influence drug metabolite concentration in hair.

Note: While commonly termed "hair follicle tests", the examination targets the hair strand, not the hair follicle beneath the scalp.
