You can go for general
health checkup which includes CBP, ESR, fasting and
post prandial blood
sugar, serum bilirubin, CUE,
TSH, serum
electrolytes,
LFT.... You can check for Vitamen D and vit
B12.
These are general tests and doesnt mean to be done compulsarily for your age.
Consult a physician if possible and let him know about your family health history... So that he may suggest.
Otherwise go for any general health checkup packages available in labs. Its good to get tests done once a year or two even though everything is normal for screening purposes.
