Does blood type O- have a positive or negative Rh factor?

Question

Or can you only know with a blood test?

Answer 1

If you look at your question you really answered it yourself!!

O- has a Neg. Rh. Factor

Just as O+ would have a Pos. Rh. Factor.

Answer 2

First of all I would like to make it clear that ;
poster has mentioned!! Its a common Misconception.
It has all the antigens against blood groups A,B,AB.
Thus an O group donates to an O group only!
__________ ________ _________ ___________ _________

Rh is the term usedto refer to all of the antigens of the Rhesus blood group system - the five main rhesus antigens (C, c,D, E and e) as well as many other less frequent antigens. The terms Rhesus factor and Rh factor are equivalent and refer to the Rh D antigen only!

Individuals either have, or do not have, the Rhesus factor (or Rh D antigen) on the surface of their red blood cells. This can be indicated with a plus (+) or minus (−) suffix after the ABO blood type (ie A- or O+)

BLOOD TYPE O- DOESNOT HAVE Rh D antigen;
IT HAS THUS A "NEGATIVE Rh factor"

You can only know it by blood testing... no other alternative!

Answer 3

RH factor is separate from the blood type. All blood types have either a + or - Rh factor. O negative is considered the universal Donor as it can be given to anyone without having to worry about a mismatch.

Answer 5

Blood type O- stands for Genotype ''O'' and Rhesus (or Rh) ''negative''. Thus it is a negative Rh factor. Hope that answers your question.

Answer 6

The - in "O-" means negative Rh factor.

Answer 7

no, blood groups depend on a type of protein on RBCs surface
but negative or positive Rh depend on another type of protein also on RBCs surface
So blood type O may be negative or positive Rh
We can know it through a specific test

and Rh type "-" (negative)

Answer 9
