Hair Follicle Drug Testing - Lake Petersburg, IL

What it is, How it works

Hair examinations are now recognized as a formidable method for identifying drug and alcohol consumption. Hair retains a long-term record of alcohol and drug intake by encapsulating biomarkers within the growing hair fibers. When obtained close to the scalp, hair can offer a detection timeframe of up to roughly 90 days for both alcohol and drugs. The collection process for hair is straightforward, challenging to tamper with, and convenient for shipping.

A 1.5-inch segment of around 200 hairs (approximately the width of a #2 pencil) nearest to the scalp yields 100mg of hair, which is the optimal sample for both screening and confirmation purposes. For EtG, additional tests, and/or assessments exceeding 10 panels, a 150mg sample is advisable. We suggest using a jeweler’s scale for weighing the specimen. If hair from the scalp is absent, an equivalent quantity of body hair can be obtained. In speaking about head hair, we specifically mean scalp hair. Body hair encompasses all other hair varieties (e.g., facial, axillary, etc.).

Process Overview

The major phases in the lab handling of a test result for drugs include Accessioning, Screening, Extraction, and Confirmation.

Accessioning pertains to the introductory handling of a specimen in a lab setting. This step ensures the sample is properly sealed and delivered, assigns a random Laboratory Accessioning Number (LAN), and fills in any additional data that might not be provided through an electronic chain of custody framework.

Screening serves as an initial rapid assessment for drug abuse. Although Screening is a budget-friendly approach to rule out drug presence in most samples, a positive screening necessitates confirmation to be legally valid. Samples flagged as potentially positive in Screening must undergo additional confirmation.

When a sample tests potentially positive during Screening, more hair is extracted from the original specimen and prepared for Extraction. In this phase, drugs are extracted from hair at substantially lower levels than seen with other methods (e.g., urine or oral fluid), which makes hair drug screening the most challenging method to execute.

Confirming any positive screening outcomes is achieved through GC/MS, GC/MS/MS or LC/MS/MS. All samples flagged as presumptively positive are cleansed before confirmation as required. The comprehensive lab process, from Accessioning through Confirmation, undergoes review under both the College of American Pathologists (CAP) Hair designation and ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests may identify drug consumption for up to 90 days, in contrast to urine tests, which have a briefer detection period.
• Difficult to manipulate: Hair drug testing is extremely challenging to deceive, which enhances the precision of results.
• Provides background data: It can reveal a pattern of drug consumption over time, unlike recent-use tests.

Limitations:

• Inability to detect recent use: Drugs require approximately 5-7 days to become detectable in hair.
• Expense: Hair drug testing is usually costlier than alternative drug testing techniques.
• Result variations: Variables such as hair color and individual hair growth differences can influence the level of drug metabolites in the hair.

Note: Despite often being called "hair follicle tests", the actual test targets the hair strand rather than the follicle beneath the scalp.

Why Hair Follicle Testing Beats Urine Testing

In Lake Petersburg, IL, hair follicle testing provides noteworthy advantages over urine testing. Hair tests offer superior detection precision, capable of identifying drug use patterns often missed by urine tests. This heightened accuracy makes hair testing the preferred choice for those seeking consistent reliability.
