Hair Follicle Drug Testing - Saint Leo, MN

What it is, How it works

Hair testing is now recognized as an effective method for identifying drug and alcohol consumption. Hair offers a comprehensive historical record by preserving biomarkers within the hair strand’s fibers as it grows. When sampled near the scalp, hair can indicate alcohol and drug usage up to roughly a three-month period. It is straightforward to collect, relatively hard to tamper with, and simple to transport.

A segment of 1.5 inches consisting of roughly 200 hair strands (comparable in size to a #2 pencil) nearest to the scalp yields 100mg, which is the ideal quantity for both screening and confirmation purposes. For EtG, additional tests, and/or tests exceeding 10 panels, a specimen of 150mg is suggested. It is advisable to measure the specimen using a jeweler’s scale. If scalp hair cannot be obtained, a similar quantity of body hair may be used. References to head hair pertain exclusively to scalp hair. Body hair denotes all other varieties (facial, axillary, etc.).

Process Overview

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

Accessioning encompasses the initial procedure of integrating a sample into a lab’s system. Tasks include verifying that the sample was adequately sealed and sent, assigning an arbitrary LAN (Laboratory Accessioning Number), and finalizing any supplementary data entry not completed by an electronic chain of custody system.

Screening conducts a preliminary rapid evaluation for drugs of abuse. Although Screening economically dismisses drugs in most samples, a positive result requires confirmation for court admissibility. Samples presumptive positive in Screening need secondary confirmation.

Samples presumptive positive at the Screening phase have more hair drawn from the original specimen for Extraction. This stage involves extracting drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), rendering hair drug screening the most complex methodology.

Confirmation of any positive result from screening is executed via GC/MS, GC/MS/MS, or LC/MS/MS. Prior to confirmation, all presumptive positive samples undergo washing as necessary. The entire lab process from Accessioning through Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and accreditation to ISO/IEC 17025 standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests can recognize drug use for as long as 90 days, compared to urine tests which have a shorter detection window.
• High resistance to falsification: Cheating is highly difficult in hair drug tests, thereby enhancing result accuracy.
• Historical usage patterns: Offers a timeline of drug use rather than only recent consumption data.

Limitations:

• Inability to detect recent consumption: It takes about 5-7 days for drugs to become evident in hair.
• Expense: Hair drug tests are typically pricier than alternate drug testing approaches.
• Result variability: Individual factors like hair color and growth rates can influence drug metabolite concentration in hair.

Note: Despite common reference as "hair follicle tests", the test evaluates the hair strand and not the follicle beneath the scalp
