Is there still a chance if the HCG level is 149 U/L 14 days after blastocyst transfer?

Under normal circumstances, blastocyst transfer refers to embryo transfer. A serum HCG level of 149 U/L 14 days after embryo transfer is still considered possible. Typically, the reference range for HCG 14 days after embryo transfer is between 100 and 2000 U/L; therefore, an HCG level of 149 U/L indicates a potential successful implantation. The detailed explanation is as follows:

Embryo transfer is a technique in which early embryos collected from a female animal's body, or embryos obtained through in vitro fertilization or other methods, are transferred into another female of the same species with a similar physiological state, allowing the embryos to continue developing into new individuals. Normally, 14 days after embryo transfer, the HCG level should fall within the reference range of 100–2000 U/L, indicating a successful transfer. Moreover, higher HCG levels generally correlate with a greater likelihood of successful implantation. Therefore, an HCG level of 149 U/L 14 days after embryo transfer falls within the normal range and suggests that pregnancy is possible.

In addition, after embryo transfer, it is essential to remain on bed rest, avoid fatigue, and refrain from strenuous activities. Diet should include nutritious, easily digestible foods. Cold, spicy, or hard foods should be avoided during this period. Adequate rest is crucial, and overexertion should be prevented. During early pregnancy, folic acid supplementation should be continued for at least three months to effectively prevent neural tube defects in the embryo. Sexual intercourse should be avoided in early pregnancy to reduce the risk of miscarriage.

If any discomfort or unusual symptoms occur, patients are advised to seek prompt medical attention at a hospital to avoid delays in diagnosis and treatment.
