PGT-A Testing in Delhi | Preimplantation Genetic Testing During IVF
A healthy-looking embryo under the microscope does not always reveal what is happening inside its chromosomes.
During IVF treatment, embryologists can assess embryo growth, development, and appearance. However, chromosome abnormalities cannot usually be identified through visual observation alone.
This is where PGT-A (Preimplantation Genetic Testing for Aneuploidy) may be recommended.
PGT-A is an advanced genetic screening technique that examines embryos before transfer and evaluates whether they have the expected number of chromosomes.
The goal is to provide additional information that can help fertility specialists make informed decisions during IVF treatment.
What is PGT-A?
PGT-A (Preimplantation Genetic Testing for Aneuploidy) is an advanced IVF laboratory technique used to evaluate embryos for chromosomal abnormalities before embryo transfer. The test helps identify embryos with the correct number of chromosomes, supporting informed embryo selection during IVF treatment.
What Does PGT-A Test For?
Human cells normally contain 46 chromosomes arranged in 23 pairs.
Sometimes embryos may develop with extra or missing chromosomes. This condition is called aneuploidy.
Chromosomal abnormalities may affect:
- Embryo development
- Implantation
- Pregnancy progression
- IVF outcomes
PGT-A helps identify embryos that appear chromosomally normal and those that may have chromosome abnormalities.
How Is PGT-A Performed?
The testing process is integrated into an IVF cycle.
IVF and Embryo Development
Eggs are fertilized in the laboratory and embryos are cultured until the blastocyst stage.
Embryo Biopsy
A small number of cells are carefully collected from the outer layer of the blastocyst.
Genetic Analysis
The sample is sent for chromosomal testing to evaluate chromosome numbers.
Embryo Freezing
Embryos are usually preserved through vitrification while test results are processed.
Embryo Transfer Planning
Results help guide embryo selection for future transfer.
Who May Benefit From PGT-A?
PGT-A is not required for every IVF patient.
However, fertility specialists may discuss the option in selected situations.
Common Situations Include
- Recurrent IVF failure
- Recurrent pregnancy loss
- Advanced maternal age
- Multiple unsuccessful embryo transfers
- Previous chromosomal concerns
- Patients seeking additional embryo information
The decision is based on individual fertility history and treatment goals.
Benefits of PGT-A
PGT-A provides extra genetic information that may support personalized IVF treatment planning.
Important Things to Know About PGT-A
PGT-A is a screening test, not a guarantee of pregnancy.
A chromosomally normal embryo still requires:
- Successful implantation
- Healthy uterine environment
- Ongoing pregnancy development
Likewise, pregnancy outcomes depend on many factors beyond chromosome assessment alone.
For this reason, PGT-A should be viewed as one component of a comprehensive fertility treatment plan.

Frequently Asked Questions
What is PGT-A in IVF?
PGT-A is a genetic screening test used during IVF to evaluate embryos for chromosomal abnormalities before transfer.
Does PGT-A guarantee pregnancy?
No. PGT-A provides chromosome information about embryos but cannot guarantee implantation or pregnancy.
At what stage is PGT-A performed?
PGT-A is typically performed when embryos reach the blastocyst stage, usually around Day 5 or Day 6 of development.
Is PGT-A necessary for every IVF cycle?
No. The need for PGT-A depends on individual fertility history, age, previous IVF outcomes, and treatment recommendations.
