Human chorionic gonadotropin levels after blastocyst transfer are highly predictive of pregnancy outcome1 Theocharis C Papageorgiou, M.D., Mark P Leondires, M.D., Bradley T Miller, M.D., Audrey S Chang, Ph.D., Alicia B Armstrong, M.D., Lynette A Scott, Ph.D., James H Segars, M.D. Fertility and Sterility Volume 76, Issue 5, Pages 981-987 (November 2001) DOI: 10.1016/S0015-0282(01)02840-0

Figure 1 Receiver operating characteristic curve for day 3 and day 5 embryo transfers based on β–hCG serum values (mIU/mL) 16 days after ovum retrieval. Solid line = day 5 values. Dashed line = day 3 samples. The value of 232 mIU/mL for the day 5 group is circled. The value of 173 mIU/mL for the day 3 group is circled. These two circles represent the optimal sensitivity and specificity for the assay. Papageorgiou. β-hCG levels after blastocyst transfer. Fertil Steril 2001.
