Viral tropism

This is a type or resistance test that is only used if you are going to use maraviroc, which is an HIV drug called a CCR5 inhibitor. 

In the UK and Europe, tropism is tested using a genotype resistance test. A special type of resistance test (testing proviral DNA) can be used if your viral load is low or undetectable.
