The doctor neither the VO will tell you what tests will be done especially sa blood tests but yung sa min blood extraction, urinalysis, xray, physical exams were done. Sa blood extraction not sure kung ano anong tests and gagawin nila dun. Depende din sa medical history mo. So it's really important that you (and each member of your family) are perfectly healthy and fit. And it's also recommended na i-advise ang doctor of any past or present health issues. Pwede mo check yung link below for more guidance.
