Peri‐implantation urinary hormone monitoring distinguishes between types of first‐trimester spontaneous pregnancy loss

Abstract

The risk of first-trimester spontaneous pregnancy loss in our prospective cohort is comparable to studies utilising daily urinary hCG collection and laboratory assays. A wider LH-hCG interval range is associated with biochemical pregnancy loss and may relate to late or early implantation. Although early hCG changes discriminate between pregnancies that will miscarry from viable pregnancies, this point-of-care testing model is not sufficiently developed to be predictive.
