Hair Follicle Drug Testing - Scotia, NE

What it is, How it works

Hair testing is now recognized as a potent technique for uncovering drug and alcohol consumption. Hair retains a historical record of substance usage by embedding biomarkers within the strands as they develop. When gathered near the scalp, hair can reveal alcohol and drug use dating back up to three months. Hair collection is straightforward, challenging to tamper with, and simple to transport.

A 1.5-inch snippet comprising roughly 200 hair strands—similar in diameter to a #2 pencil—is ideal, equating to 100mg of hair, suitable for both screening and validation. For EtG, supplemental assessments, or panels exceeding 10, a 150mg sample is advisable. It's suggested to measure the sample weight using a jeweler's scale. If scalp hair is not an option, an equivalent volume of body hair can be taken. When mentioning head hair, it specifically refers to scalp hair, while body hair includes all other types (such as facial and axillary hair).

Process Overview

Drug test results undergo four essential laboratory procedures: Accessioning, Screening, Extraction, and Confirmation.

Accessioning marks the initial phase where a sample enters a laboratory system. This step verifies the integrity of the seal and shipment of the sample, allocates a random LAN (Laboratory Accessioning Number), and fills in any missing details not provided by an electronic custody chain.

Screening provides a preliminary analysis for potential abuse of drugs. Although Screening offers a budget-friendly method to exclude drug ingestion in most cases, a positive result must undergo confirmation for legal validation. Samples with a presumptive positive outcome in Screening proceed to the confirmation stage.

Upon a presumptive positive result during Screening, additional hair is extracted from the collected sample for the Extraction phase. This step isolates drugs from hair at much lower concentrations compared to other methods (like urine or oral fluid), highlighting the intricate nature of hair drug analysis.

Any positive findings in screening go through Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS techniques. All samples suggesting a positive result are cleansed before confirmation if necessary. The full laboratory procedure from Accessioning to Confirmation adheres to the CAP (College of American Pathologists) Hair guidelines and complies with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Extensive detection period: Capable of identifying drug use for up to 90 days, unlike urine tests with shorter detection periods.
• Hard to deceive: The difficulty in manipulating hair drug tests enhances result reliability.
• Tracks usage history: Offers a timeline of drug use rather than identifying only recent intake.

Limitations:

• Incapable of noting recent usage: Drugs become traceable in hair approximately 5-7 days after use.
• Expense: Hair drug tests are typically pricier compared to alternative drug testing approaches.
• Result deviations: Individual factors like hair color and growth variations can influence the levels of drug substances in hair.

Note: Although often called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the skin.
