May not be worrisom: We would to know a lot more to say if this is a problem. What medications do you take, what other medical problems do you have. These could occur for a variety of reasons and you would need other testing as this may be simple like trauma or more related to an internal medical problem.

Strange: I find it odd that your doctor told you that you have petechiae, didn't bother to take a history, and then jumped straight to laboratory studies. If you do have petechiae, it might be a cutaneous vasculitis. If so, your doctor should determine what the cause is and whether other organs are involved. They may also result from trauma or arthropod bites, though. MCHC and MPV values are insignificant.

No: But may want to be some other tests like vitamin C, D and thyroid levels.
