Can you get a negative urine pregnancy test even if a blood test comes back positive?

I have just this minute come back from the doctor. My urine test was negative but my blood test was positive. I have been told that my HCG levels are extremely low therefore producing a negative urine test. I was also told that I am either 1-2 weeks pregnant or that I am in the process of a miscarraige. I had an internal exam and my cervix is closed which is a good sign! I would suggest to you if you had the same thing happen to wait a few days and go back and have both tests done again to see where your levels are at. Either way, keep a close eye on it. Hope this helps.

How it is possible for some one to test negative on a simple urine test and positive on the standard test?
Pregnancy tests measure the level of hcg in your body. When you are pregnant, and as your pregnancy progresses, your hcg level rises. When you take a urine pregnancy test and it comes back negative, the level of hcg is not high enough to register on the test. When the quantitative serum pregnancy test is positive, it is a more acurate reading of how far along in your pregnancy you actually are.
What does it mean when a blood hcg test comes back with neg and pos on it?
If an hCG test comes back positive, it means the person is pregnant. If it comes back negative, the person is probably not pregnant, but it could be a false-negative if testing was done too soon.

YES. Maybe both of your parents are half-Rh positive, but not a full-blown Rh positive.

What are the implications of having type a negative blood?
The negative blood comes from the rhesus scale. So type A negative blood means you are rH negative. This poses a potential problem during pregnancy if the mother is rH negative and the father is rH positive. In that case the mother will receive a rhogam shot during pregnancy and right after birth to prevent the potential mixing of blood between mother and child from causing a serious reaction in the mother's body.
If a man has RH positive Blood type and the woman has RH negative blood type will the mom to be have to take shots so she does not miscarry?
No. The RhoGAM (Human Immunoglobulin D) shots are for the Rh negative (Rh-) mother. If it is a first pregnancy, there is usually not an issue. For any terminated pregnancy, by abortion or by miscarriage, then there is usually a RhoGAM shot given in effort to prevent the mother from forming antibodies against any Rh positive child. At the beginning of each pregnancy, the mother's blood "titer" is check -- this will indicate if she HAS formed any antibodies against the Rh positive blood type.
Can blood be either B positive or negative?
Not exactly. Human blood may have positive (ca. 80%) or negative (remaining 20%) Rhesus factor. It means that that a substance known as Rhesus factor is either found or not in a human blood test.

A problem known as Rhesus conflict may arise when a Rhesus-negative woman is pregnant with a Rhesus-positive baby.The name Rhesus factor comes from Rhesus monkey in which it was first found.
