Introduction

The IgG/IgM rapid test is a serological test that detects the presence of Immunoglobulin G (IgG) and Immunoglobulin M (IgM) antibodies in a person's blood. These antibodies are produced by the immune system in response to infections, including viral infections. The test helps in the early detection, diagnosis, and therapeutic assessment of infectious diseases.

Test Overview

The IgG/IgM rapid test is designed to provide quick and precise results. It typically functions via a small blood sample, which is placed on a test strip. Results are often available within 10 to 30 minutes. This rapid testing method is especially valuable during pandemics or outbreaks, where large numbers of tests need to be conducted in a short period of time.

IgG/IgM Detection

The IgG/IgM test targets two main antibodies:

• IgM: This is the first antibody produced by the immune system in response to a new infection. A positive result indicates a recent exposure or an active infection.
• IgG: This antibody appears later and indicates a past infection or a developed immunity. A positive result suggests previous exposure to the pathogen.

Analytical Statistics

The sensitivity and specificity of the IgG/IgM rapid test are pivotal for accuracy. For instance, studies have shown sensitivity rates for IgM around 85-95% and for IgG around 90-98%. The specificity typically ranges from 95% to 99%. These figures can vary based on the specific test brand and the population being tested.

Company Solutions

Various companies manufacture IgG/IgM rapid tests, each offering unique features:

• Company A: Offers a test with 92% sensitivity and 98% specificity with results in 15 minutes.
• Company B: Provides a test kit with integrated digital read-out for ease of use, ensuring precision in interpretation.
• Company C: Features a portable testing solution that is ideal for remote or low-resource settings, maintaining a 90% sensitivity rate.
