The only way to know if your virus is undetectable is to get a test where the doctor takes blood. This test will show how much virus there is in your blood on that day. If the amount of virus in your blood is below the limit that the test can measure, then you are considered to have an undetectable viral load. If you are being treated for HIV, your doctor will measure your viral load every 3-8 months, on average.
