When is pregnancy tested in IVF?

We recommend testing for pregnancy 12 days after embryo transfer. Getting an earlier result is possible, but to prevent confusion a blood test should be done at day 12. Since tracking the value tested for in the blood test is important, a blood test should be preferred over an urine test.

How is the pregnancy test done?

The days between embryo transfer and the pregnancy in IVF are the most impatiently awaited days for an expectant mother and father. It takes 10 to 12 days for the embryo implanted in the uterus to secrete a hormone called beta-HCG and for this hormone to reach measurable levels on the mother’s blood. On the 12th day, a blood pregnancy test which measures this hormone is done and the pregnancy result is learned.

There is no need to be hungry or full on this test. Patients who can’t come to our clinic for the pregnancy test can have this test done in any nearby biochemical lab.

We invite our patients who have a positive pregnancy test to an ultrasound check for the detection of the gestational sac 10 days after a positive test result. Our patients who are in a different city or abroad can do these checks in different clinics.

How is the gestational week calculated in IVF?

Gestational week is calculated based on the measurements of the embryo seen in ultrasound.

Early determination of gestational week is crucial for both the planning of pregnancy tracking and to determine the expected date of birth.

How is the date of birth calculated based on the gestational week?

The pregnancy process takes approximately 280 days (40 weeks). For both doctors and expectant mothers it is more accurate to track the pregnancy with ``weeks`` instead of the more commonly used ``months``. For example, a pregnancy should be described as 26-27 weeks instead of 6.5 months.
