Project: Utilization of Electrochemiluminescence immunoassay (ECLIA ) for the detection of Early Embryonic Biomarkers for Embryo Selection

In assisted reproductive technology (ART), the grading systems based on morphology and stage of embryo development has been the primarycriteria to identify the embryos with high competence to transfer.However, morphological evaluations are subjective and imprecise and not always in accordance with embryo implantation potential. Other invasive and non-invasive methods such as genomics, proteomic and metabolomic profiles of spent culture media were explored for embryo assessment but unfortunately none of them gave conclusive results.

Some of the mot simple and obvious biomarkers with potential to add information in the detection of highly viable embryos were not taken in consideration. Hyperglicosylated -hCG is one of the first embryonic signals of viable blastomeric/trophoblastic cells to the endometrium and this molecule was detected by different investigators in culture media containing embryos at different stages of embryo development (day 2 to 5).

Different technologies were utilized to detect H-hCG but the sensitivity and repeatability of the diagnosis was a major limitation factor. Electrochemiluminescence immunoassay (ECLIA) technology is a method based on solid-phase sandwich immunoassay with advantages of superior sensitivity to detect different molecules including H-hCG levels of 0.100mIU/ml in plasma or urine samples, taking only 20 minutes for the completion of the assay.

The aim of this project is to evaluate the profile of H-hCG levels secreted by individual fresh and frozen/thawed embryos and detected by a modified electrochemiluminescence immunoassay (ECLIA) in spent embryo culture media from day1 to day6 of culture. We also aim to explore it’s utilization as a complementary biomarker for embryo competence assessment in clinical IVF-ET procedure.
