Respiratory 4-Plex Panel 

COVID-19, Flu A&B, and RSV Testing Service

Introducing the DiaCarta Clinical Laboratory’s comprehensive diagnostic test, designed to accurately identify and differentiate between three prevalent respiratory viruses, SARS-CoV-2 (responsible for COVID-19), Influenza A and B (causing the flu), and Respiratory Syncytial Virus (RSV). All three viruses exhibit similar symptoms, including coughing, fever, and difficulty breathing, making distinguishing them crucial for effective treatment and disease management.

Our cutting-edge Lab Developed Test (LDT) employs qRT-PCR technology to efficiently and accurately detect the presence of these viruses, enabling healthcare providers to monitor their spread and implement targeted intervention strategies.

By offering a rapid and precise diagnostic solution, the test empowers healthcare professionals to control the spread of infectious diseases better, ultimately improving patient outcomes through tailored treatment approaches.
