When is PGT-M recommended for genetic risk in related couples?

Being related does not identify one exact genetic diagnosis. The relevant question is whether both partners carry changes linked to the same recessive condition, or whether the family history points to another inheritance pattern. PGT-M tests embryos for a particular condition; it is not a general screen for every genetic difference.

A genetics professional may review the family tree, previous diagnoses, laboratory reports, and results from carrier testing. The laboratory usually needs confirmed genetic information before it can design a test, and the process may take planning before IVF begins.

Arrange genetic counselling and bring any family test reports. Testing both partners can clarify whether they share a condition-related variant and whether relatives may need testing to establish the diagnosis. The team will discuss IVF, embryo biopsy, laboratory preparation, and how results guide transfer decisions.

Ask whether prenatal testing would still be offered after an embryo transfer. PGT-M is targeted to the condition being tested, so a pregnancy may need follow-up testing and routine antenatal care.

Seek prompt medical advice for pregnancy bleeding, severe abdominal pain, fainting, fever, or any urgent symptom during fertility treatment or pregnancy. Genetic risk planning is important, but these symptoms require clinical assessment rather than waiting for test results.

Which condition is being tested, and is its genetic cause confirmed? Can the laboratory build a test for our family? What results can PGT-M provide, and what follow-up testing is advised in pregnancy?
