IVF beta-hCG timing

When is Beta-hCG Tested After Transfer in IVF?

What is Beta-hCG?

Beta-hCG is a hormone that rises in the blood when pregnancy occurs. It is used to determine if pregnancy has occurred after embryo transfer.

When Should It Be Tested?

It is generally recommended to perform a blood beta-hCG test 10–12 days after embryo transfer.

Timing According to Embryo Day

• Day 3 embryo transfer → Day 12
• Day 5 (blastocyst) transfer → Day 9–10

Can Testing Be Done Earlier?

Tests performed too early can be misleading. False negative or false positive results may be seen.

Are Home Pregnancy Tests Reliable?

Home urine tests are not reliable in the early stages. The most accurate result is obtained with blood beta-hCG.

How Are Results Evaluated?

• Positive → Pregnancy may have occurred
• Negative → Pregnancy may not have occurred
• Repeat testing is required for suspicious values

How is Follow-up Done?

After a positive result, beta-hCG is monitored every 48 hours. The value is expected to approximately double.

Clinical Significance

A beta-hCG test performed at the correct time prevents unnecessary stress and misinterpretations.

Conclusion

In IVF treatment, the most accurate time for a pregnancy test is 10–12 days after transfer. Earlier tests can be misleading.
