Question 1

is rh d neg blood rare?

Accepted Answer

No: It varies from population to population. In folks of european descent, around 1 person in 6 is rh negative (class d-neg). It's less common in some other populations.

Question 2

what factors decide whether you have blood that is negative or positive?

Accepted Answer

Blood typing: Your question is too vague. Negative or positive for what? If you mean rh positive or negative, blood typing would tell you. The rh factor like the blood type is inherited from your parents.

Question 3

urinalisys came out with blood trace microscopic and negative for chemical, what could that means?

Accepted Answer

Depends on details: That just means maybe some red blood cells were seen in the urine. The patient then has to recheck with her doctor to decide if there were or were not blood cells there. Sometimes trace blood is from vaginal bleeding. Usually, repeating the urine test a couple of times on days when there is no vaginal bleeding should show urine without red blood cells. One's doctor can follow up.

Question 4

can there be really a blood type u negative?

Accepted Answer

Yes, there is: The u antigen belongs to the mns blood group system. The u antigen, together with the s and s antigens, is expressed on glycophorin b (gpb), a red blood cell membrane glycoprotein. U− subjects are always also s- and s−. Only 1.2 percent of african americans are u-.

Question 5

negative blood group, what is the significance?

Accepted Answer

Basically none: If you are Rh negative, it doesn't mean "bad". It's simply that you don't have a protein, and if your father's child gives the protein to your unborn child, you can become sensitized. Your physician knows how to deal with this.

Question 6

what will happen if you have a negative blood type?

Accepted Answer

See below: There is no such thing as a negative blood type. I think you mean the rhesus factor is negative, as in A- vs. A+. The negative doesn't mean much except when the father of a developing fetus is positive and the mother is negative. On a subsequent pregnancy, it can cause problems for the fetus but this is prevented with a medicine called Rhogam.

Question 7

to whom can people with negative blood donate blood to?

Accepted Answer

Of course: You are likely referring to the rh factor which follows the letter(-s) of blood type as (+) or (-). It's not quite a 50/50 split, but both positive and negative donors are needed. Call the red cross at 1-800-red-cross for more information, local donation center and an appointment!

Question 8

if blood test comes out neg too and still no pd...wat does tht mean?

Accepted Answer

See your OB/GY: our menses and periods can be irregular or delayed for many reasons. Please see your OB/GYN and he or she can do a thorough check up.

Question 9

is it in any way possible to get a false negative on a blood peegnancy test?

Accepted Answer

No, not Realy: Some of your symptoms sound like pregnancy.  Perhaps the next test will be different.   You may become pregnant after the first test if you are sexually active.   See a physician for an examination to be sure.  Backache is not usual in early pregnancy but can be seen in urinary infections.

Question 10

what exactly does a negative report mean in context of a blood culture report?

Accepted Answer

No bacteria found: It means that no bacteria were found in the blood.
