Which are the essential prenatal tests that must be done?

Patient's question:

No

Doctor's answer:

A check-up within the first 3 months of pregnancy (including blood, urine, blood pressure, weight, and other physical examinations) is recommended to provide a baseline for future comparisons and to detect any potential issues early on. Between the 3rd and 4th months of pregnancy, a Down syndrome screening can be performed to check for any fetal abnormalities.
