Two reviews in people with blood cancers receiving intensive chemotherapy or a stem cell transplant found that overall giving platelet transfusions when the platelet count is less than 10 x 10 9 /L compared to giving platelet transfusions when the platelet count is less than 20 or 30 x 10 9 /L had no effect on the risk of bleeding.

In India, as per Ministry of Health, the blood donation interval criteria for apheresis requires at least 48 hours interval after platelet- or plasma-apheresis. Any donation should not be done more than two times a week and should be limited to 24 times in one year. [4] [5]
The risk of severe bacterial infection is estimated, as of 2020, at about 1 in 2,500 platelet transfusions, and 1 in 2,000,000 red blood cell transfusions. [44] Blood product contamination, while rare, is still more common than actual infection.
Platelets are often life-saving and special in that they can help up to 3 adults or even 12 children. As platelets can only be stored for a few days, regular and frequent donors are in great demand and that is why platelet donors are asked to attend at least 8 to 10 times per year.
The single unit policy is helpful in platelet transfusion as there this blood component has a short shelf-life than other components. Assessment after one bag can include assessing clinical bleeding, platelet count looking at the post transfusion increment and/or functional platelet assessments. [8]
If antigen negative platelets are unavailable, then standard neonatal platelet transfusions should be given until antigen negative platelets become available. [20] [19] If a platelet transfusion is not available immediately then the infant can be given IVIG (1g/kg) however, this will have no effect on the platelet count before 24 to 72 hours. [19]
How many hours do people work a year? The average employee works 2,080 hours each year. However, the average person also takes 10 vacation days, 8.5 sick days and 10 government holidays.
The change in the recipient's platelet count after transfusion is termed the "increment" and is calculated by subtracting the pre-transfusion platelet count from the post-transfusion count. Many factors affect the increment including body size, the number of platelets transfused, and clinical features that may cause premature destruction of the ...
