Hyperemesis Gravidarum

Screening and Tests for Hyperemesis Gravidarum

When morning sickness continues longer than it should, screening for hyperemesis gravidarum should be done to verify the condition and that the symptoms do not indicate a different problem such as hydatidiform mole.

Diagnosing hyperemesis gravidarum begins when symptoms of nausea and vomiting continue after the first trimester of pregnancy. The medical history will be established and a physical exam performed that may reveal low blood pressure accompanied by a high pulse. The doctor will prescribe a hematocrit, a blood test, and urine ketones test to check for signs and amounts of dehydration. Additional tests used in diagnosing hyperemesis gravidarum check for gastrointestinal and liver problems.

A hormone test showing too high blood levels of HCG (human chorionic gonadotropin) may indicate multiple fetuses or may indicate the presence of a hydatidiform mole. A pelvic exam and an ultrasound can rule out these possibilities, helping narrow the diagnosis to hyperemesis gravidarum.
