How long does endometrial receptivity testing take to work for implantation failure?

The test samples the uterine lining during a cycle prepared to resemble a transfer cycle. The sample is examined for a pattern associated with receptivity, and the laboratory report is reviewed with the fertility team. The practical benefit therefore comes later, when the result is interpreted alongside embryo, uterine and hormonal factors.

A result may suggest keeping the planned transfer timing or adjusting it. Testing cannot confirm that implantation will occur, and it does not identify every reason an embryo may not implant.

Ask the clinic for the sampling date, expected report window and the next appointment to discuss the result. Follow the prescribed cycle medicines exactly, and tell the team about bleeding, missed doses, infection symptoms or a change in the planned cycle. Write down how the result will alter the transfer plan before consenting to the next step.

After sampling, contact the clinic for heavy bleeding, severe or increasing pelvic pain, fever, faintness or unusual discharge. During fertility treatment, seek urgent advice for severe abdominal swelling, breathing difficulty or sudden intense pain.

Ask what the test measures, when the report should arrive, how it may change transfer timing, and which other explanations for implantation failure will be considered.
