A viral culture is a laboratory test in which a small sample
of tissue or fluid that may be infected is collected and placed in a container
along with cells in which a virus can grow. If a virus grows in the culture, it
causes changes in the cells that can be seen under a microscope, and the virus
can be identified.
It may take several weeks for a viral culture to grow and be
tested. Then it may help a doctor learn the cause of an infection.
