Yeah, I've found a very comprehensive package for 5000, but it's just blood and urine.
For an extra 5k, at a hospital, I could get that plus exercise stress test, stool examination, EKG, chest x-ray, and full abdominal ultrasound.
I think it could be worth paying extra. The blood tests are great, but I could miss out on something serious like blood in stool or blocked arteries.
I know the topic here says annual checkup, but I'd probably not do this again for quite a while (depending on results), so I am looking for a very comprehensive screening.
