Hair Follicle Drug Testing - Ronneby, MN

What it is, How it works

Hair analysis is now recognized as a highly effective method for identifying drug and alcohol consumption. Hair serves as a comprehensive record of substance use by entrapping biomarkers within the strands’ fibers as they grow. When acquired close to the scalp, hair offers a detection period of up to roughly three months for alcohol and various drugs. Hair collection is straightforward, relatively tamper-resistant, and easy to transport.

A 1.5-inch segment of roughly 200 hair strands (comparable to the thickness of a #2 pencil) nearest the scalp yields 100mg of hair, the preferred sample quantity for both initial screening and subsequent confirmation. For EtG, additional tests, or panels exceeding 10, a 150mg specimen is advisable. We suggest using a jeweler’s scale for precise weighing. If scalp hair is unavailable, a comparable amount of body hair may be utilized. "Head hair" specifically refers to scalp hair, whereas "body hair" encompasses all other types such as facial or axillary.

Process Overview

Key stages in the laboratory processing of a drug test include Accessioning, Screening, Extraction, and Confirmation.

During Accessioning, the sample is initially processed into the lab’s system. This encompasses confirming that the sample was appropriately sealed and dispatched, assigning a random LAN (Laboratory Accessioning Number), and completing any supplementary data entry not covered by an electronic chain of custody system.

Screening entails a preliminary rapid assessment for substances of abuse. While Screening is a cost-effective approach to exclude drug use in most samples, a positive result requires verification for legal admissibility. Samples that are initially positive in the Screening phase necessitate a confirmatory test.

For samples flagged as presumptively positive during the Screening phase, additional hair is extracted from the initial sample for further Extraction. In this phase, drugs are isolated from hair at a much lower concentration than in alternative methods (e.g., urine or oral fluid), making hair drug screening the most intricate methodology to execute.

Verification of any positive Screening outcomes is accomplished via GC/MS, GC/MS/MS, or LC/MS/MS. All samples initially deemed positive are washed prior to confirmation as required. The complete laboratory procedure from Accessioning to Confirmation is evaluated under both the CAP (College of American Pathologists) Hair designation and in adherence to ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection timeframe: Hair drug tests can reveal drug use up to 90 days back, as opposed to urine tests with a shorter detection span.
• Challenging to manipulate: Hair drug tests are notably hard to tamper with, thus ensuring more reliable outcomes.
• Historical usage patterns: They offer insight into drug usage trends over time, not merely recent use.

Limitations:

• Inability to detect recent drug use: Drugs become noticeable in hair after about 5-7 days.
• Expense: Hair drug tests are typically costlier than other drug testing techniques.
• Result variability: Variations in hair attributes like color and growth rate can impact drug metabolite levels in the hair.

Note: Although termed “hair follicle tests,” the test actually examines the hair strand itself, not the follicle beneath the scalp.
