Conclusion. A single serum 2-hCG level on d 11 after embryo transfer has good predictive value for clinical pregnancy outcome in controlled ovarian stimulation cycles and helps to plan the subsequent follow-up.o assess the clinic value of a single maternal serum beta-human chorionic gonadotropin (2-hCG) assay 11 d after embryo transfer in ART pregnancies and to predict pregnancy outcome. A total of 384 pregnancies after embryo transfer were included.
Implantation will usually occur somewhere between 6 and 12 days past ovulation. Once the fertilized egg implants, the developing placenta begins releasing hCG (human chorionic gonadotropin) into the blood. Some hCG also gets passed into the urine. hCG levels usually double every 2-3 days in early pregnancy. Once the levels are high enough they can then be picked up by a home pregnancy test. Depending on the pregnancy test brand and when implantation occurs for you this will range from 10-16 days after conception has occurred. Pregnancy test sensitivity will be your next consideration. The sensitivity of home pregnancy tests vary quite widely from brand to brand - anywhere from 10 mIU to 250 mIU.
