Hi there, I try to tell everyone that we are not dr.'s. Only your dr. knows why he ordered which blood tests, and in what range he wants the test results to be. It is his profession to interpret these. I have known some people try to interpret their blood tests themselves, and at the end, they are so panic-stricken that they are scared stiff. Always have your dr. review your tests with you at your next appt. Be well.
