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.
