Blood typeedit
From Memory Alpha, the free Star Trek reference
Blood type, sometimes also refered to as Blood group, is a characteristic of Human red blood cells determined by the presence of specific surface antigens. Human blood type designations commonly use two systems for determining blood transfusions: the AB designation and the Rh factor designation, although there are other systems in use for other purposes. There are four AB types and two Rh types, yielding eight types: O+, A+, B+, AB+, O-, A-, B-, AB-. O is the designation used when the blood cells in question possess neither A nor B antigens. O-positive is the most common blood type in most early 21st century Human populations.
Detroit prostitute Georgia Tandy had a blood type of O-negative. Captain Archer told Loomis and T'Pol that his blood type was B-negative. (ENT: "Carpenter Street") Likewise, Julian Bashir had type B-negative blood. (DS9: "In Purgatory's Shadow")
Vulcans appear to use a similar system for blood type designation, as both Spock and Sarek had T-negative blood. (TOS: "Journey to Babel")
Curzon Dax and Jadzia Dax both had different blood types. Bashir cited this as evidence of how different Trill are to each other, despite carrying the others memories. (DS9: "Dax")
After being changed into a Solid by the Great Link, Odo's blood type was O-negative. (DS9: "Broken Link")
