Hair Follicle Drug Testing - Eveleth, MN

What it is, How it works

Hair analysis is recognized as an effective method for detecting drug and alcohol consumption. Hair retains a prolonged record of alcohol and substances by embedding biomarkers in the growing fibers of the hair. When gathered close to the scalp, hair can offer up to around a 90-day detection period for alcohol and drugs. Hair collection is straightforward, relatively tamper-proof, and easy to transport.

A sample measuring 1.5 inches with roughly 200 hair strands (similar in size to a #2 pencil) near the scalp yields 100mg of hair, which is the optimal sample for testing and verification. For EtG, additional tests, or panels exceeding 10, a specimen weighing 150mg is advisable. It is recommended to measure the specimen using a jeweler’s scale. If scalp hair is not an option, a comparable amount of body hair may be used. References to head hair are solely about scalp hair. Body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of 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 verifies the sample's proper sealing and shipment, assigns a random LAN (Laboratory Accessioning Number), and fills in any missing data not captured by an electronic chain of custody system.

Screening offers an initial, rapid assessment for drug presence. Although cost-effective for ruling out drug use in most cases, positive screening results require confirmation for legal validity. Any samples flagged as presumptive positives in Screening must undergo secondary confirmation.

For samples flagged as positive during Screening, further hair is taken from the initial sample for Extraction. This stage extracts drugs from hair at much lower concentrations than other methods (e.g., urine or oral fluid), highlighting why hair drug testing is the most challenging to perform.

Confirmation of positive screening results is executed via GC/MS, GC/MS/MS, or LC/MS/MS. All samples presumed positive are washed before confirmation as necessary. The complete laboratory process, from Accessioning to Confirmation, is evaluated under the CAP (College of American Pathologists) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extensive detection length: Hair drug tests can identify drug use for up to 90 days, whereas urine tests have a more limited detection period.
• Hard to manipulate: Hair drug tests resist manipulation, ensuring more reliable results.
• Reveals usage history: They exhibit a pattern of drug usage over time, not just recent consumption.

Limitations:

• Incapable of recent detection: Drugs become detectable in hair after approximately 5-7 days.
• Expense: Hair drug testing tends to be costlier than other testing techniques.
• Result variations: Variables like hair color and personal hair growth rates can influence drug metabolite levels in hair.

Note: Though often termed "hair follicle tests", the process examines the hair strand, not the follicle beneath the scalp
