A link between PdG and pregnancy

High PdG levels could indicate a successful pregnancy

We came across a couple interesting articles looking at the link between elevated PdG levels and pregnancy outcome. The data suggest that in a successful pregnancy, PdG levels remain elevated, as seen below. However, PdG levels declined in the late luteal phase of non-conception cycles and when early pregnancy loss occurred. Furthermore, they also show that elevated PdG levels could be used as a possible diagnostic tool for early pregnancy. Currently, early pregnancy health is measured as a function of hCG doubling time. The authors suggest that high PdG levels in early pregnancy could be a more accurate measure. While this research is very exciting, we don’t know if Proov tests can be used as an early pregnancy diagnostic. However, in a near future, we hope to conduct our own research studies to help answer this important question.
