Non-invasive prenatal testing.
Non-invasive modalities to assess the ongoing pregnancy may assist the clinician to identify risk factors requiring additions or alteration to routine prenatal care. These modalities include pedigree analysis, maternal serum alphafetoprotein screening, fetal ultrasonography, and Doppler ultrasound. These methods should be used when there are appropriate clinical indications and awareness of their limitations.
