What tests will i need in the second trimester of my pregnancy?

Afp, ultrasound: Between 15 and 20 weeks you should be offered the second trimester screening or "afp" test which assess risk for some fetal chromosomal and anatomic abnormalities via a maternal blood test. This is not a diagnostic test. Most will also be offered an ultrasound at approx 20 weeks to screen visually for anatomy and fetal growth. The diabetes screeening test will happen at the beginning of third tri-.

Dr Livingston and another doctor agreed

Screening tests: Tests in second trimester are meant to screen for fetal abnormalities and defects. Ultrasound examination and blood tests for afp, beta hcg, estriol, inhibin may be done to assess placental health, neural tube defects, trisomy etc.
