Can I still have a tummy tuck with high RDW-SD and RDW-CV?

Hi, thank you for your question. 
RDW is a test to determine abnormalities that occur with the red blood cells. Most commonly it is used in conjunction with the MCV to determine the underlying cause of anemia. 
Your internist or hematologist will be the only person who can determine if you are a safe candidate for tummy tuck where you can expect some amount (50-150mL) of blood loss during the operation. 
Photos would be helpful to see if a tummy tuck is even an option for you or if another less invasive method can help you reach your goal. Always consult with a board certified plastic surgeon for an in-person evaluation before making your decision. 
I hope this helps. Good luck in reaching your aesthetic goals!

Dear Ms. Akasha55,
Thank you for your questions and photos.
Unfortunately without a in person consultation, review of your past medical history and a physical exam I am limited to provide general but hopefully helpful information.
The values you are referring to are known as “indices”. They reflect different aspects of the blood cell. They are used to test your red  blood cells to detect abnormalities. Most commonly it is used in conjunction with the other indices to determine the various cause of anemia. Depending on the levels and in conjunction  with other factors can result in low levels of hemoglobin (oxygen carrying component of blood).
Cosmetic Plastic Surgery is “want to have surgery” not “need to have surgery”.  Thus it is always optimal to be in the best physical condition and have normal laboratory values prior to surgery. 
I suggest you contact your primary care doctor for a evaluation of your blood tests. If needed he/she can refer you to hematologist who has additional expertise in blood analysis. 
I trust your chosen Plastic Surgeons is a experienced and Certified by the American Board of Plastic and ideally a member of the American Society for Aesthetic Plastic Surgery (denoting by membership as having met additional criteria and a focus on Cosmetic Plastic Surgery).
My best wishes and a successful safe surgery,
