Platelet increment after its transfusion

Q: How long does it take to peak platelet count after its transfusion? 

Answer: About 10 minutes to an hour 

It takes about 10 to 60 minutes after a platelet transfusion to have its peak value. Transfused platelets usually survive in the blood for about three days in contrast to bone marrow produced platelets which have a half-life of about ten days.

 A transfusion of one apheresis platelet, which is an equivalent to six units of pooled platelets approximately increase platelet count by 30,000/microL in an average adult.
