Best PGT-A/PGT-M (Genetic Testing of Embryos) doctors in Bengaluru

Genetic embryo testing costs depend on the number of embryos tested and screening types. Overall charges include In Vitro Fertilisation—an assisted reproduction procedure—and laboratory analysis. PGT-M testing requires custom gene probes, which adds specialized laboratory design expenses. Patients should request written price breakdowns from international patient coordinators before travel. This ensures full clarity on treatment expenses prior to clinical visits.

Clinics measure embryo testing success by tracking live birth rates per transferred healthy embryo. Identifying chromosomally normal embryos helps reduce miscarriage risks during fertility treatment. Individual success factors depend on maternal age, egg quality, and underlying health conditions. Patients should discuss expected outcome statistics directly with their treating medical team. This provides realistic expectations tailored to personal medical history.

PGT-M does not automatically include PGT-A testing because each screens for different genetic issues. PGT-M detects specific single-gene disorders inherited from carrier parents. PGT-A checks overall chromosome numbers to prevent implantation failure. Specialists can run both tests on a trophectoderm—the outer embryo layer—biopsy sample. This dual approach evaluates specific disease risk and general chromosome health.

The recommended PGT test depends on family genetic history and personal fertility goals. PGT-A benefits patients facing unexplained miscarriages or advanced maternal age. PGT-M assists couples carrying known single-gene conditions like cystic fibrosis. A clinical geneticist—a doctor studying inherited conditions—reviews parental health records. This evaluation guides the correct laboratory testing strategy for each family.

PGT-M testing achieves high accuracy levels for detecting identified single-gene inherited conditions. Modern DNA sequencing techniques reliably identify mutational patterns in embryo biopsy samples. Rare mosaicism—a mix of normal and abnormal cells—can sometimes affect test interpretation. Doctors recommend confirmation testing during early pregnancy to verify embryo genetic results. This additional verification step ensures complete clinical confidence for expecting parents.

PGT-M is a targeted genetic screening test performed on embryos before implantation. The acronym stands for Preimplantation Genetic Testing for Monogenic disorders. It identifies specific single-gene mutations, such as sickle cell anemia or thalassemia. Testing helps embryologists—laboratory scientists managing embryos—select healthy embryos for transfer. This process prevents passing serious hereditary health conditions to future generations.

Doctors recommend PGT-M testing when prospective parents carry specific inherited single-gene conditions. It is appropriate when family history shows high risks for inherited medical disorders. Couples who previously had a child with a genetic condition also benefit from testing. Carrier screening—blood tests checking inherited gene mutations—determines if testing is necessary. Specialists guide patients through testing requirements based on carrier test results.

Embryo biopsy involves removing a few cells from a blastocyst on day five of development. A blastocyst is an embryo developed for five days inside an incubator. Embryologists extract cells from the trophectoderm, which forms the future placenta. This delicate procedure leaves the inner cell mass—the future fetus—completely untouched. Biopsied embryos remain safely frozen while genetics laboratories analyze the extracted cells.

Genetic counseling provides clear guidance on family medical history and test options. A genetic counselor explains inherited disease risks and laboratory testing procedures. They review carrier screening reports to identify specific gene mutations requiring analysis. Counselors also discuss test limitations and ethical aspects of embryo selection. This consultation helps families make informed choices before starting treatment.

Genetic test results for PGT-A and PGT-M typically require two to three weeks to process. The laboratory analyzes DNA extracted from embryo biopsy samples during this window. PGT-M requires extra setup time beforehand to build customised genetic test probes. Embryos remain safely stored in cryopreservation—medical freezing—while waiting for results. Specialists plan embryo transfers only after reviewing final genetic reports.
