Is It Ok to Have Rhinoplasty if Platelets Result is 428,000?

In general platelets are a good thing as they help you stop bleeding.  Lab tests may at times vary from the 'normal' range for many reasons (i.e. dehydration).  Ask your surgeon what he/she thinks.

428,000 is not too much above the normal range so I would normally not consider it a problem. Even normal platelet counts can be a problem if the platelets are not functioning properly. If there is any doubt your surgeon can have you get a bleeding time test to test the function of your platelets.

My response to your question/post does not represent formal medical advice or constitute a doctor patient relationship. You need to consult with i.e. personally see a board certified plastic surgeon in order to receive a formal evaluation and develop a doctor patient relationship.

The normal range for platlets is 150,000 to 400,000.  If your Rhinoplasty Surgeon is concerned or there's something in your medical history found by your family doctor, you can see a hematologist for evaluation.  

That platelet count should not be a problem when you have a rhinoplasty. However, I'm assuming that your medical history is normal and you will consult with an internist or hematologist before the surgery is scheduled.

I doubt it would be a problem but that is a question best asked of a hematologist. That is the medical speciality that takes care of issues relating to your question.
