How long do PGT Results take?


The time to receive the results of Preimplantation Genetic Diagnosis (PGD) generally ranges from 2 to 4 weeks, although this timeframe can vary depending on various factors. We spoke with Álvaro Martínez, Laboratory Director at Vida Fertility, to shed light on this.

Preimplantation Genetic Testing

What is Preimplantation Genetic Diagnosis (PGT)?

Preimplantation Genetic Testing (PGT) is a cutting-edge tool in embryo selection, allowing for the detection of potential genetic abnormalities before transfer to the maternal uterus.

It is classified as PGT-A when focusing on global chromosomal analysis and as PGT-M when assessing specific genes, enabling precise embryo selection in assisted reproductive treatments.

How long does it take to get PGT results?

The time to receive the results of Preimplantation Genetic Diagnosis (PGD) generally ranges from 2 to 4 weeks, although this timeframe can vary depending on various factors, such as the specific technique used and the genetics laboratory involved.

Some labs even offer the option of obtaining a diagnosis in as little as 24 hours, but these situations are exceptional and subject to cost and risk considerations.

It’s important to mention that, in cases where a prior genetic study is required to analyze hereditary diseases, the process can be further extended.

The duration of this preliminary process can vary based on the complexity of the pathology and the amount of information available about the disease, extending up to 2 months. After this period, assisted reproduction treatment can proceed, culminating in genetic diagnosis. In summary, the entire process can take up to 4 months, depending on the specific circumstances of each case.

PGT Results

When you receive the results of Preimplantation Genetic Diagnosis (PGD), they can be classified into four different categories:

-Normal (Euploid): This means the embryo has the correct number of chromosomes, including the 23 pairs that make up the human genome, including the sex chromosomes. This is a positive sign for implantation potential.

-Abnormal (Aneuploid): In this case, the embryo has an incorrect combination of chromosomes, which can lead to difficulties in implantation, spontaneous abortions, or fetal development incompatible with life.

-No Diagnosis: Sometimes, it’s not possible to determine the chromosomal makeup of the embryo. This could be due to technical problems or limitations in the quality of the embryo and may require a new biopsy.

-Possible Mosaic: Some embryos may show a combination of cells with normal chromosomal makeup (euploid) and others with abnormal chromosomal makeup (aneuploid).

These results are crucial in the process of embryo selection, as they help identify embryos with a higher likelihood of successful development and, consequently, increase the chances of a healthy pregnancy.

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

If healthy embryos are not obtained, there are two alternatives: consider an additional cycle of In Vitro Fertilization (IVF) with Preimplantation Genetic Diagnosis (PGD) or explore the option of using donor eggs or sperm. The decision will be based on various factors, such as whether you have previously undergone unsuccessful IVF-PGD cycles and the recommendations provided by fertility clinic specialists based on your specific case.
