Introduction

China's rapid influenza diagnostic tests (RIDTs) have become a crucial tool in managing flu outbreaks by providing timely and accurate diagnosis. These tests are known for their ability to quickly identify the type of influenza virus, thus helping in curbing the spread of infection.

Technology Overview

The quick flu test developed in China employs advanced nucleic acid amplification techniques. The predominant method is the reverse-transcription polymerase chain reaction (RT-PCR), which targets the viral RNA of the influenza virus.

Mechanism of Action

The test starts by collecting a nasopharyngeal swab from the patient. The sample is then placed in a viral transport medium and subjected to lysis to release viral RNA. The RT-PCR process involves reverse transcription of RNA into complementary DNA (cDNA), followed by amplification using specific primers. A fluorescent probe binds to the amplified DNA, resulting in a detectable signal that confirms the presence of influenza virus.

Performance Metrics

The quick flu test provides results in approximately 30 minutes with a sensitivity of approximately 95% and specificity exceeding 98%. These parameters are based on a study involving 10,000 participants with confirmed flu cases. The test's limit of detection is approximately 50 viral particles per microliter.

Immuno Company Solutions

The Immuno Company has developed a proprietary platform that enhances the efficiency and accuracy of rapid influenza testing. Their solution features integrated sample preparation and automated RT-PCR analysis, reducing the potential for human error. With a throughput capacity of 500 tests per hour, their system is designed to handle high-volume testing environments.
