Hair Follicle Drug Testing - Vilas, WI

What it is, How it works

Hair analysis has emerged as an effective method for identifying drug and alcohol consumption. Hair captures a prolonged record of alcohol and drug presence by embedding biomarkers within the strands of growing hair. Collected near the scalp, hair can reveal drug and alcohol use for a span of up to three months. Its collection is straightforward, hard to tamper with, and simple to transport.

An approximately 1.5-inch segment containing 200 hair strands (roughly the width of a #2 pencil) closest to the scalp will produce 100mg of hair, the preferred amount for both screening and confirmation. For EtG, additional testing, and tests exceeding 10 panels, it's advisable to have 150mg of the hair. A jeweler’s scale is recommended for weighing. In the absence of scalp hair, a similar amount from body hair can be utilized. References to head hair pertain solely to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The key stages in the lab processing of a drug test result include Accessioning, Screening, Extraction, and Confirmation.

In Accessioning, a sample is initially entered into a lab’s system. This involves checking that the sample remains sealed and is shipped correctly, allocating a random Laboratory Accessioning Number (LAN), and finalizing any data entry absent from an electronic chain of custody.

Screening offers an initial rapid evaluation for drugs. Though cost-effective to exclude drug use for most samples, a positive screen necessitates confirmation to be valid in legal proceedings. All samples with a presumptive positive from Screening must undergo secondary confirmation.

For samples presumed positive during Screening, additional hair is extracted from the initial sample and prepared for Extraction. In this phase, drugs are extracted from hair at lower concentrations than other methods (e.g., urine or oral fluid), highlighting the complexity of hair drug screening.

Confirmed positive results from Screening are verified using GC/MS, GC/MS/MS, or LC/MS/MS. Samples presumed positive are washed pre-confirmation as needed. The entire lab process from Accessioning to Confirmation follows the CAP (College of American Pathologists) Hair designation and aligns with ISO / IEC 17025 standards.

Advantages of hair drug testing:

• Prolonged detection period: Hair drug tests can identify drug usage for up to 90 days, whereas urine tests cover a shorter timeframe.
• Challenging to manipulate: Hair drug tests are difficult to deceive, ensuring more reliable results.
• Provides a historical overview: Hair testing reveals drug usage patterns over time, beyond just recent activities.

Limitations:

• Does not reveal recent consumption: Drugs require about 5-7 days before becoming detectable in hair.
• Expense: Hair drug tests are typically costlier compared to other testing methods.
• Result variability: Factors like hair color and individual differences in hair growth can influence the levels of drug metabolites in hair.

Note: Commonly termed "hair follicle tests", the analysis focuses on the hair strand, not the follicle beneath the scalp.
