How Long to Get Results from PGT-A

Women who had two or more miscarriages, failed implantation, older than 35 years, diagnosed with unexplained infertility, and underwent numerous unsuccessful fertility treatments can choose PGT-A, Preimplantation Genetic Testing for Aneuploidy.

So, exactly after the embryo retrieval phase, some patients will consider PGT-A tests for analyzing the chromosomal abnormalities. It enhances the success rate by up to 50% and reduces miscarriages.

The results of PGT-A tell a special story about the 23 pairs of chromosomes. But, how long will it take? This blog will provide you with the answers and the success rate of IVF after PGT-A screening. Let’s get started.

Timeline for PGT-A Results

PGT-A results usually take around one to two weeks. It depends on the health condition of every individual. Let’s know about the process and why it takes so long.

When it comes to medical treatments, results rely on the health condition of the individual most of the time. Similarly, if a patient has any complex chromosomal disorder, then it could take around 2 to 4 weeks to summarize the results.

Okay, what could be the possible test results? You can expect four different types of results such as Euploidy, Aneuploidy, Mosaic, and no result.

Euploidy: The embryo consists of 23 pairs of chromosomes and is ready for transfer, which is a normal condition.

Aneuploidy: This is an abnormal condition that has more chromosomes than the normal 46 chromosomes. It suggests that the embryo is suitable for transfer and pregnancy.

Mosaic: It is a critical stage because both abnormal and normal chromosomes are mixed. According to the ratio of abnormal and normal chromosomes, the pregnancy results will be measured.

For instance, if the abnormal chromosome count is less, then the chances of conceiving a healthy baby are high. When the situation is vice versa then following the doctor’s advice is the best thing to do.

No result: Due to poor quality or inadequate number of chromosomes, PGT-A results will become inconclusive. Additionally, misinterpretation can also be a reason for such test results.

How accurate is PGT-A?

People opt for PGT-A tests to identify chromosomal abnormalities and get successful pregnancy results. Current PGT-A techniques are quite accurate, it may give false results.

Yes, sometimes, the PGT-A test may provide the wrong information such as missing an abnormality or detecting one that isn’t there. In some cases, viable embryos called Mosaic embryos can also be discarded. It’s because these embryos could lower the chance of pregnancy.

So, consult your fertility expert to get personalized advice on PGT and IVF treatments. They can suggest the right treatment methods according to your age, reproductive health, and current body condition.

What should I do If I don’t get healthy embryos?

Couples or patients undergoing IVF treatment know very well that healthy embryos are essential for successful results.

If the embryos are unhealthy, then it increases the risk of miscarriages and genetic diseases. That’s an important reason to consider genetic screening and tests. So, you can try PGT-A and other tests to improve the fertility treatment results.

Other than testing, what can you do for unhealthy embryos? You can opt for healthy donor embryos. In general, recipient couples often try to match blood type, eye and hair color, weight, and even ethnicity, extracurricular interests, academic capability, family history, and more.

Patients can discuss such things with their fertility experts and make sure to check everything they need to get a healthy baby.

What is the success rate of PGT-A?

Genetic tests like PGT and PGS can increase the success rate of fertility treatments, as these tests can ensure the embryo selected for transfer has the correct number of chromosomes.

Screening can reduce fertility treatment failure and miscarriages. Still, age is a significant factor that contributes to pregnancy success rates. Also, there is a huge difference between women who do and don’t undergo the PGT-A before the fertility treatments.

Why does PGT take so long?

Women over 37 years old with a history of failed IVF cycles, miscarriages, and a family history of chromosomal problems choose PGT-A tests. It takes a long time as this procedure has multiple steps. 

Embryologists remove a single or number of cells from the embryo, then cells are tested for chromosomal abnormalities. Then, the embryos without chromosomal abnormalities are placed back into the womb.
