Secondly, one is generally allowed to donate platelets anywhere from every 3–28 days. This is a stark contrast to whole-blood donation, which has an eight-week (or longer) waiting period between donations. Along those lines, since platelet donation does temporarily remove whole blood from the body, it may be necessary to wait eight weeks after a whole blood donation to donate platelets, although two weeks is more common. In the US, a donor is only allowed to donate 24 times each year and may not lose more red blood cells or plasma in a year than they would from the maximum allowable number of whole blood donations. In India, as per Ministry of Health the blood donation interval criteria for apheresis requires at least 48 hours interval after platelet/plasma - apheresis. The donation should not be done more than 2 times a week and should also be limited to 24 times in one year.
