My father (61yrs) is having Diabetes, Hypertension and Cholestrol for which he is taking medicines. My family background has a history of old age dementia; where I have seen the patient suffers from forgetting even his family members. I want my parents (father and mother both) to get checked up thoroughly as both of them are ageing, and i want to be assured of their good health. Please guide me what are the general tests required for thorough investigation, for which i mean blood tests ( thyroid/cbc/kft/lft/sugar/cholestrol etc ) or any other , if required. Is "full body test packages" in differnt health centres or labs are sufficient? Please suggest..
