Yes, a prenatal paternity test can be done before the child is born, typically through amniocentesis or chorionic villus sampling (CVS). However, this procedure carries a small risk of miscarriage and should be done only after consulting with a medical professional.

The time it takes to get paternity test results can vary depending on the laboratory conducting the test. In general, most laboratories can provide results within a few days to a few weeks.

A court order is not always required for a paternity test, but it may be necessary if the test results are to be used in legal proceedings, such as child support or custody cases.

While a paternity test is designed to determine biological relationships, it can also provide information about a person's ancestry or ethnicity. However, there are other DNA tests, such as autosomal DNA tests, that are better suited for determining ancestry or ethnicity.
