CVS stands for Chorionic Villus Sampling. It is a type of diagnosis which is carried out to determine whether a fetus is suffering from any genetic disorder or not. It is performed by collecting samples from the fetus and then testing it using different technologies, and then finally, it is determined whether there is any disorder.

FISH is the short form of the medical term Fluorescence in situ hybridization. It is a type of cytogenetic technique that helps determine the type of disorder in a CVS procedure. This method works by binding probes to several parts of nucleic acid where it feels that disorder symptoms can be found.

Initially, this process was only carried out to look for symptoms of down syndrome, but now it is used for testing more than two hundred disorders in the fetus. The results are pretty accurate and give correct information regarding any disorder.

Why Does It Take That Long For FISH Results After CVS?

There are various reasons because of which a need to carry out CVS can be identified. These include abnormal results in the screening of the first trimester. Sometimes it is also done because some abnormalities are found in the ultrasound report of the mother. In many cases, genetic disorders get inherited by the mother or father, and then there might be a need for CVS. If the mother’s age is above thirty-five, then there are high chances that the fetus might be having genetic disorders, and that’s why CVS is carried out.

Some certain risks and complications are also involved in the CVS procedure. Approximately one percent of CVS cases result in miscarriage, and hence the decision to go for CVS is a compassionate one. There are also risks of infection and fluid leakage from the mother’s body, which can be painful and might weaken the mother’s immunity. Limb Reduction Defects are also known to take place in patients on whom CVS is done.

It takes that long for FISH results after CVS before multiple tests are needed to be carried out on the sample that is obtained from the fetus. Also, results are cross-checked at least twice to ensure no errors in the final result. Therefore, patients should keep patience while waiting for CVS reports.
