Generally speaking, if the initial screening is normal, there is no need for genetic testing; if there is a family history or if the initial screening is positive, genetic testing is required.
The initial screening for anemia is a 15-point blood test, which is usually performed in early pregnancy. If there is no family history and both test results are normal, the pregnancy can continue without genetic testing, but special circumstances cannot be ruled out.
If the blood test is positive, or if there is a family history of the disease, further hemoglobin analysis should be performed on both parties, and then according to the type of analysis, genetic testing for anemia should be performed to determine whether to continue the pregnancy or terminate the pregnancy.
Pregnant women are advised to have regular checkups, and the doctor’s recommendation should be used to determine whether or not to perform the test.
