Quick blood test for pregnancy of unknown location
Part of Women’s health & pregnancy clinical trials.
This study tests a quick blood test that helps doctors figure out if a pregnancy of unknown location is likely to be a normal pregnancy or an ectopic pregnancy (where the pregnancy grows outside the uterus). It aims to give you a faster and more accurate risk assessment so you get the right care sooner.
Summary written for real people, not researchers, by Clin2.

This trial tests if a rapid blood test can replace ultrasound for women who want a very early medical abortion (before 6 weeks). It aims to make care simpler and faster.
This study uses a scope placed in the uterus to find and treat a pregnancy that can't be located on ultrasound. It may help women with slow-rising pregnancy hormone levels find out where the pregnancy is and get treatment at the same time.
This study tests a new blood test that might help check the health of your baby early in pregnancy. It aims to see if the test can work well without needing more invasive procedures.
This study looks at a blood test done early in pregnancy (NIPT) to see if it can help predict conditions like preeclampsia, preterm labor, or gestational diabetes. If you had this test and had a healthy pregnancy or one of these complications, you may be able to join.
This study tests a new blood test to track how the body responds to treatment during pregnancy, especially for those at risk of high blood pressure conditions. It may help doctors monitor and improve care.
