I am a 30 year old, on dialysis and am i currently pregnant at 21 weeks. i had to do a blood test to check the possibility of my baby having downsyndrome and the test results came back intermediate. should i worry.

Worry a little: In general, a woman can ask her doctor to describe any additional tests that are available or needed to better tell if the baby fetus has a major mutation, and to discuss what "intermediate risk" numbers mean. For example, if there is a 1/300 chance of DS, that means 299 out of 300 babies are expected to NOT have Down Syndrome.

Would it matter: Screening tests are meant to select out those with a bit higher risk than the general population.Then a more expensive definitive test can be obtained for the people that want the information.It is the standard of care.Some in your position would want the relief that comes from a negative definite test, some would want to plan ahead if positive. Only you can decide what the information is worth
