Hair Follicle Drug Testing - Lake City, MI

What it is, How it works

Hair testing is increasingly recognized as an effective method for detecting drug and alcohol consumption. It captures a long-term record of drug and alcohol presence by embedding biomarkers in hair shaft fibers. When gathered near the scalp, it offers a detection span of up to approximately 3 months for alcohol and other substances. The collection process is straightforward, with a lower risk of tampering and easy transportability.

A 1.5-inch hair sample, roughly 200 strands (comparable to the thickness of a #2 pencil) nearest the scalp, yields 100mg, which is the optimal amount for both screening and confirmation. For EtG, additional panels, or tests exceeding 10 panels, a 150mg sample is advised. Use a jeweler’s scale to measure the specimen's weight. If scalp hair isn't available, an equivalent amount of body hair is permissible. Here, head hair refers exclusively to scalp hair, while body hair includes all other types (facial, axillary, etc.).

Process Overview

The laboratory processing of a drug test result involves four primary steps: Accessioning, Screening, Extraction, and Confirmation.

Accessioning is the initial step where a sample enters the lab system, verifying proper sealing and shipping, assigning a random LAN (Laboratory Accessioning Number), and completing any extra data entries outside of an electronic chain of custody system.

Screening is a preliminary rapid assessment for drugs of abuse, providing a cost-effective way to eliminate drug usage in most samples. However, any positive screen requires confirmation to be court-admissible, with presumptive positives necessitating secondary confirmation.

Should the Screening stage yield a presumptive positive, extra hair is extracted from the initial sample and readied for Extraction. Drugs are isolated from hair at lower concentrations than other methods (such as urine or oral fluid), making hair drug testing the most challenging methodology.

Any positive screening result undergoes Confirmation via GC/MS, GC/MS/MS, or LC/MS/MS. All presumptively positive samples are cleansed before confirmation as necessary. The complete lab process from Accessioning to Confirmation is governed by both the CAP (College of American Pathologists) Hair criteria and the ISO / IEC 17025 accreditation standards.

Advantages of hair drug testing:

• Extended detection period: Hair drug tests identify drug use up to 90 days, unlike urine tests with a shorter span.
• High resistance to cheating: Hair drug tests are difficult to deceive, enhancing result accuracy.
• Reflects usage history: It provides a usage pattern over time rather than only recent consumption.

Limitations:

• Cannot detect immediate use: Drugs appear in hair approximately 5-7 days post-use.
• Cost: Hair drug tests typically cost more than other drug testing methods.
• Result variability: Factors like hair color and individual growth differences can impact metabolite concentrations.

Note: Despite being called "hair follicle tests", the analysis is conducted on the hair strand, not the follicle beneath the scalp.
