| Platelets are the cells that stick together to form blood clots. Normally they don't stick together, but when there is a disturbance in the blood vessels (such as a broken vessel) then they stick together at that point and prevent blood from coming out of the vein or artery. | |||
| Platelets can be separated from the rest of donated blood and given to patients who need them. A (see-through) bag of them is pale orange. | |||
| A normal platelet count in a healthy person is between 200 and 400. (Actually that's 200 to 400 bazillion, maybe someone can clarify). People can live independently with a count as low as 20. People can live in hospital with a count as low as 5, but spontaneous bleeding gets to be a problem. That's when platelet transfusions have to be done. | |||
