After IVF, the most awaited step is confirming pregnancy. Usually, 15 days after embryo transfer (ET), doctors advise a Beta hCG blood test. This test is the most accurate way to know whether implantation has been successful.

Below is a clear explanation by an experienced IVF doctor in Delhi about expected hCG levels 15 days after embryo transfer, what they mean, and what to do next.

What Is hCG?

hCG (Human Chorionic Gonadotropin) is a hormone produced after the embryo implants in the uterus.

• It is released by the developing placenta
• Rising hCG levels indicate a progressing pregnancy

hCG Levels 15 Days After Embryo Transfer

hCG levels vary from woman to woman, but the following ranges are commonly used as a guideline.

Expected hCG Levels (mIU/ml)

???? In most IVF cases, hCG ≥ 100 mIU/ml at 15 days after ET is considered reassuring.

Fresh vs Frozen Embryo Transfer hCG Levels

• Fresh Embryo Transfer
  hCG levels may be slightly lower initially, but steady rise is most important.
• Frozen Embryo Transfer (FET)
  hCG levels are often more stable and sometimes higher.

Why Is Rising hCG Important?

A single positive hCG result is not enough.

✔ hCG should roughly double every 48–72 hours

Example:

• Day 15: 120
• Day 17: 230–250

This pattern suggests a healthy early pregnancy.

Causes of Low hCG at 15 Days After ET

• Late implantation
• Embryo quality issues
• Inadequate hormonal support
• Chemical pregnancy

???? Doctors usually advise a repeat Beta hCG test to assess the trend.

What Do High hCG Levels Mean?

• Strong implantation
• Possibility of twin pregnancy
• Good placental development

⚠️ Twins cannot be confirmed by hCG alone; an ultrasound is needed.

What to Do After a Positive hCG Test

✔ Continue all prescribed medicines
✔ Repeat hCG test after 48 hours
✔ Avoid heavy work and stress
✔ Follow a healthy diet and lifestyle

If hCG Is Negative

✔ Do not panic
✔ Do not stop medications on your own
✔ Consult your IVF doctor to discuss next steps

Yes, if taken recently. Always inform your doctor.
