The standard blood test for kidney function measures creatinine. You will probably need the help of a doctor to interpret the result. And a doctor who knows you well will know what other tests might be appropriate in your situation.
But everyone should get standard liver function tests. There are a few of these and you might as well get them all but the most useful in order to observe the effect of febuxostat are called ALT and AST. If you have no other illness which is affecting these values, they are a bit easier to interpret than the kidney test but it would still be best if you had access to older test results for comparison. There is also a test called bilirubin which is not standard everywhere and may be relevant as well but I don’t think there’s much point in insisting on it as long as your ALT and AST values are OK.
Long story short, best arrange the blood test with a doctor! Febuxostat is not such a common drug so doctors can not be expected to know all about it, but any doctor surely is familiar with standard blood tests so you can simply ask for liver function tests and they’ll know what to do.
