Tests and diagnosis
By Mayo Clinic staffMorning sickness is typically diagnosed based on your signs and symptoms. If your pregnancy care provider suspects hyperemesis gravidarum, you may need various urine and blood tests. Your pregnancy care provider may also do an ultrasound to confirm the number of fetuses and detect any underlying conditions that may be contributing to the nausea.
