Caption
This is a saggital view of the uterus belonging to a patient who returned to the emergency department after persistent vomiting. An initial urine pregnancy test performed yielded a negative result however this patient’s ultrasound scan ultimately revealed a molar pregnancy. As Dr. Jones explains, this patient false-negative urine pregnancy test is explained by a phenomenon known as the High Dose Hook Effect.
