All about Genetic DiagnosisAll about Genetic Diagnosis - Dr Hit

To ensure the safety of couples and the babies, about to enter the world, genetic diagnosis is conducted to identify any hereditary disease that your body could be carrying. In recent times, the human genome map has been one of the major successes for the science of genetics, and therefore helps improve the success of IVF treatments.

The Diseases You Never Thought Existed

A disease, known as cystic fibrosis, has around 500 mutations, and for this reason, it is extremely essential to test the couples’ for any diseases that could cause harm to their health and/or their future baby’s. There are around 1400 genetic diseases that could carry disorders in them, the disorder carrying diseases can cause birth defects.
