What is blood?

What's your type?

Blood comes in four "types" (A, B, AB and O) with each being either positive or negative. Some blood types are more common than others, with O being the most common. Every unit donated at BloodSource goes through over a dozen tests including infectious diseases, hepatitis, HIV, and West Nile Virus to name a few, to ensure that it as safe as possible for the patient. We also conduct blood type testing.
