Viral Hemagglutination Assay

A Viral Hemagglutination Assay is a laboratory test that detects and measures viruses based on their ability to cause red blood cells (like those in blood) to clump together. The virus binds to the red blood cells, forming a visible layer or clumps. By diluting the sample and observing the point where red blood cells no longer clump, scientists can determine the amount of virus present. This test is commonly used to identify certain viruses and assess their level in samples, providing crucial information for disease diagnosis and research.
