Objective-To improve the interpretation of future studies in women who are initially diagnosed with a pregnancy of unknown location (PUL), we propose a consensus statement with definitions of population, target disease and final outcome.

Access to expertise and equipment for high-quality TVS means the majority of women with EP in developed countries can be diagnosed rapidly and accurately. Identifying PUL, which are low risk and therefore requiring less follow-up, finding better serum markers for EP and safely identifying women who do not require intervention for EP are the current diagnostic challenges.

In unselected women attending an EPU, pregnancy location can be diagnosed accurately in over 90% of all pregnancies and in 73.9% of ectopic pregnancies with a single TVS.
