Has anyone had a blood test while being on rivaroxaban ? At my GP's request after a year on the drug I had one a few days ago . I remember it's for liver and kidney function , but sure there's something else . My Doctor wants to speak to me this afternoon so I'm waiting for the phone call as I can't get in to see him because I'm working . I'm worrying what this test has thrown up , as thinking it can't be too bad as I'd be in A&E by now ! Any thoughts anyone ?
