Platelets are so variable and are easily affected by how the blood was collected.
I've had blood taken from my port and then blood taken from my arm 5 minutes later and the results were different by over 40,000. On another occasion blood taken from my port was repeated an hour later and had dropped by quite a lot. Turns out the second sample had platelets that had clumped together and were therefore not included in the count.
Platelet counts can be unreliable but I think it pays to repeat the count just before any transfusion is to be given just to verify the previous result was accurate.
Regards
