Can pregnant women get the thalassemia test at the same time as the Down syndrome screening?

Patient's question:

No

Doctor's answer:

Hello, the best time for the Down syndrome screening is the 15th to 20th week of pregnancy. Generally, pregnant women can receive the screening results within one week after blood draw. If there are no abnormalities, one test is sufficient. If there is no thalassemia in both families (mainly based on the test results of you and your partner, which may be hidden thalassemia), there is no need to test.
