Is there any chance I could get small samples of human blood (including A,

[~stairway to heaven~]

B, AB, & O) for an experiment? Now I don't mean litres of blood, or a lot of it.. but like a small test tube sample, aprox. 3 of each blood type. Would that be possible? Could I get samples that are infected with a mild virus which are the cause of common fevers/flu's,etc?
