Can the Tang-style screening results be checked by computer in advance?

Patient's question:

No

Doctor's answer:

Based on your last menstrual period, you are 16 weeks and 3 days pregnant as of August 9th. Prenatal screening for Down syndrome can be performed between weeks 14 and 20, with weeks 16 to 18 being the optimal time for the test. Your test time is just right, not too early.
