Please understand that the swish test, is referring just to a simple collection method. Testing for the virus, and its subtypes is a time consuming expensive process. Your insurance is not going to pay for this as the test is part of a clinical trial OCF conducted with Gillison. PCR testing and other methods are capable of finding the virus. But they are done slightly differently by each laboratory so if you are into paying for this out of pocket, stay with the same lab each time.
