Too sensitive a: Question. It is not clear what you mean by blood test. If it is a screening test, then you need to get additional tests, like amniocentesis done for a definitive answer. Please discuss the matter with your doctor and i wish you and your baby the best.

High chance: Positive screening should be confirmed by karyotyping of fetal cells obtained through amniocentesis. Consult your obstetrician for further details.
