Viva-E System: Streamlined Drug Testing with EMIT Technology

Wiki Article

The Viva-E System by Siemens Healthineers is an automated immunoassay analyzer built specifically for clinical drug testing. It utilizes EMIT (Enzyme Multiplied Immunoassay Technique), a proven technology for detecting drugs of abuse and therapeutic drug levels. Compact yet powerful, the Viva-E supports routine and stat drug screening needs in hospitals, rehabilitation centers, and clinical labs.

In this article, we’ll explore how the Viva-E system works, its core features, benefits for toxicology labs, and the test types it supports.

What Is the Viva-E System?

The Viva-E is a bench-top immunoassay analyzer optimized for drug testing. It automates the entire workflow—from sample loading to result reporting—using EMIT technology, a gold standard in toxicology labs for over four decades.

This system is ideal for clinical environments that need rapid and accurate drug screening, including:

• Pain management clinics

• Workplace drug testing labs

• Hospital toxicology departments

• Rehabilitation and addiction recovery centers

What Is EMIT Technology?

EMIT (Enzyme Multiplied Immunoassay Technique) is a type of competitive binding immunoassay. It measures the presence of drugs or their metabolites in a sample, usually urine or serum. Unlike other immunoassays, EMIT does not require separation steps, making it ideal for high-throughput and automated analysis.

How it works:

1. The sample is mixed with specific antibodies and enzyme-labeled drug molecules.

2. The real drug in the sample competes with the labeled drug for binding to the antibody.

3. If more of the target drug is present, less enzyme-labeled drug binds to the antibody.

4. The enzyme activity is measured to determine the drug concentration.

This technique offers fast results, high specificity, and cost-effective operation for routine testing.
