trying to guess another medical provider's rationale for doing tests is like predicting what my wife wants me to do on my day off. impossible. a blood test for pregnancy is considered to be more accurate in detecting pregnancy than a urine test so many providers will do a blood test as a back-up. i have no idea why your doctor would do any prenatal tests if you are not pregnant but an rh factor will not change so perhaps she is just adding it to the blood tests so that you can avoid getting stuck again? just a guess. your doctor is trying to determine why you are spotting so this is just the beginning of the diagnostic testing.
doc today did a pap test then asked me to do urine preg test few mins later she did a blood test. why all the tests? . i am on nortell 7/7/7 and have had a brown spotty discharge every 2weeks in the last 2 months. last real period was in september. since then been this brown stuff. doc said it is old blood that hasnt fell out and she don't kno why. she did not tell me the urine test results and said tomro she will tell me what is test results. i do kno i asked her about a rh factor blood. she said only if i am preg will she do the test but i overheard her tell the nurse to test for it.
