By itself platelets at 45 is not unusual. Since my transplant in Jul 2014 my platelets averaged 54 with a low of 11 and dozens of readings below 20. until 6 months ago I was steady at 70 for several months. Then it jumped to 140 for the past 6 months. The cause of the sudden increase was a blood clot that ran from my groin to below the knee. This is not the recommended way to increase platelets.
