IQ and VIQ

These tests are rarely used in the UK.

They were a way to individualise treatment using the Inhibitory Quotient (IQ) or Virtual Inhibitory Quotient (VIQ). These blood tests report on how well your virus reproduces (called “viral fitness”). 

IQ and VIQ tests were being integrated with TDM and resistance tests to further individual results.

These tests might still sometimes be used in research but they are not generally available.
