Two years ago when I was pregnant with my first child I had the same test and the ratio was 1:1800. When discussing options with patients, physicians should provide information on detection and false-positive rates, advantages and disadvantages, limitations, and the risks and benefits of each screening test and diagnostic procedure so that the patient can make an informed decision.
