Patient's question:
36 days after your last menstrual period, self-testing showed a weak positive result, and blood HCG testing revealed 2500 mIU/mL. Can this confirm pregnancy? Can the duration be determined?First follow-up question: What does a blood HCG level of 2500 mIU/mL indicate? Why is it written as U/L in other places?
Doctor's answer:
Hello, early pregnancy (gestational weeks are calculated from the first day of the last menstrual period) Week 3: 5.8-71.2 mIU/ml; Week 4: 9.5-750 mIU/ml; Week 5: 217-7138 mIU/ml. Specific results may vary depending on the instrument and unit system used by the testing hospital. Preliminary analysis of your test results shows they are within the normal range. This is because the timing of fertilization varies among different women's menstrual cycles, leading to slight differences, so there is no need to worry too much.
