Mandatory medical device diagnostics.
- Sonography (ultrasound examination)
- Biometry (measurement of the fetus/unborn child) [esp. reduced fetal abdominal circumference].
- Amniotic fluid volume (oligohydramnios).
- Doppler sonography (ultrasound examination that can dynamically visualize fluid flow (especially blood flow); measures blood flow pattern in uterine arteries (uterine arteries) and fetal blood flows in arteries and veins) in the pregnant woman) – to assess fetal supply/infant supply [pathologic Doppler flow measurements: In the presence of impaired uteroplacental perfusion at the time of the 19th to the 22nd week of gestation, fetal growth restriction (IUGR, intrauterine growth restriction) can be detected with a sensitivity of 15-70% and with a specificity of up to 95% (1)].
- Cardiotocography (CTG; cardiac tone-wave recorder) [pathological heart rate patterns].
Optional medical device diagnostics – depending on the results of the history, physical examination and obligatory laboratory parameters – for differential diagnostic clarification.
- Biophysical profile (fetal respiratory movements, fetal body movements, fetal muscle tone, fetal reactivity).
