Testing a blood marker in repeated pregnancy loss
Part of Women’s health & pregnancy clinical trials.
This study looks at whether a blood protein level called mannose binding lectin is linked to why some people have repeated pregnancy loss or unsuccessful embryo transfers. If you’ve had multiple losses or failed transfers, the study may help clarify biology behind reproduction and could guide future care.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 to 45 years old
- You have had either: three consecutive pregnancy losses (after natural conception), or three consecutive losses after fertility treatment (IVF/ICSI/FET), or three failed embryo transfers with no pregnancy using good-quality embryos
- You can have a blood sample taken when you are not more than 9 weeks pregnant (at the time of blood draw)
- You should not have major uterine shape problems or known uterine lining diseases (like endometriosis inside the uterus, adenomyosis, abnormal thickening, or polyps)
- You should not have known chromosome (genetic) abnormalities
- Your AMH level is usually expected to be at least 4.0 pmol/L unless you used donor eggs in earlier cycles

This study looks at immune-related blood patterns and other measurements to better understand why some women have repeated pregnancy loss or repeated IVF implantation failure. If you qualify, your answers and test results may help researchers identify biomarkers that could guide future care.
This study looks for genetic clues in ongoing and past pregnancies to help explain why some people miscarry repeatedly. The results may help doctors better predict and prevent future pregnancy loss.
This study looks at the lining of the womb in women who have had repeated failed embryo transfers, to understand why implantation may not happen. By taking a small sample of the womb lining, researchers hope to find clues that could improve future treatment.
This study looks at the lining of the uterus (womb) in women who have had repeated IVF failures or miscarriages, to see if differences in the lining's germs or immune system might play a role. The goal is to find ways to improve future fertility treatments.
This study tests whether a simple blood test taken before embryo transfer can help predict if the embryo will implant successfully. It is designed for women who have had unexplained repeated implantation failure and are planning another IVF cycle with frozen embryos.
This study explores a new supportive care program for people who have had multiple pregnancy losses and are pregnant again. It aims to see if extra attention and care can help reduce the risk of another loss.
