Thanks for your question.
Slight elevation in platelet count can be caused by the stress.
Also any inflammation in the body can cause this change.
Anemia is another possibility.
Just raised platelets without any other change in white cell count or red cell count, is not concerning.
This does not suggest cancer or anything serious.
Repeat blood test should be performed to confirm your platelet count.
Besides, dehydration is another common cause of raised platelet count.
This does not sound concerning.
