Why do doctors take blood tests?
Blood tests are like snapshots of what is going on inside your body. An ultra sound shows a pic of your organs, but the blood test results show more comprehensive info. When they ask for more tests, it means some of the tests you already took showed something they want to get more infomation about. There are varying levels of tests they do with the blood, each more revealing than the last. You should call your doc and ask him what he’s looking for. It’s your body and you should have all the info.
