Noninvasive embryo viability assessment by quantitation of human haptoglobin alpha-1 fragment in the in vitro fertilization culture medium: an additional tool to increase success rate

Viability of the embryo during the IVF process is assessed by microscopic inspection, resulting in a pregnancy rate of 25%-30%. Detection and quantitation of the α-1 haptoglobin fragment of the culture medium proved to be a useful additional method for identifying nonviable embryos, increasing the success rate to 50%.
