What's your blood type??

I quote just to clarify the universal blood types: O + O positive donors are needed more frequently than any other donor. Because O positive is the most common Blood type (39% of the population), it is needed more often by people requiring Blood in hospitals. O - 7% of the population has O negative Blood. People with O negative donors are potential universal red Blood cell donors. This means that their red Blood cells can be transfused to patients with all types of Blood. Simply put, your Blood is tested for ABO/Rh. These tests identify your 'Blood type.' You may have A, B, O, or AB type Blood and may be either Rh+ or Rh-. The basis of the Blood group tests is the ability to detect specific substances, or antigens, on the red Blood cells. The A antigen is on type A cells; the B antigen is on type B cells. If neither A nor B antigens are detected, the donor has type O Blood; if both are present, the donor has type AB Blood. If the major Rh antigen is present, the donor is Rh+ (for example, O+, A+, B+, or AB+); if not, the donor is Rh- (O-, A-, B-, or AB-). There are more than 600 other antigens that have now been identified on red Blood cells. These sub-types are important, but often not considered. http://www.bloodbook.com/type-facts.html

Mine is O negative as well, but it is a shame now as I cannot give blood due to my diabetes condition but in an emergency I suppose they would have to use it.

you should inquire about it: it's very important
