Types of genetic testing:

There are different types of genetic tests done by a medical specialist, each varies according to the requirement and the symptoms associated. The tests are done with the help of saliva or taking a blood sample and the results can be received in a few weeks.

It is pertinent to mention that all family members share the same strains of DNA. In case of any change or defect in any gene, it can cause a genetic change in the other family members as well. The process of genetic counselling is recommended to check if checking your gene mutation with the help of genetic testing is the preferred option. It also ensures if your test was taken right and the results are also accurate.

The reason behind genetic testing:

  • If any preventive measure is needed for curing any malignant disease, like cancer
  • If there is any chance that future pregnancy could lead to any genetic condition due to an underlying genetic disorder in the family

Tests apart from Genetic testing:

There are of course some other tests as well which are recommended by the doctors apart from typical genetic testing in Singapore. Those are:

Chromosome testing: Mainly the DNA structure is packed inside the chromosomes. Some tests are performed to change the chromosomal number in the body rather than causing any change in the genes. These tests are chromosomal microarrays and karyotype.

Gene Expression tests: In different parts of the cells, genes are either turned on or expressed at different levels. The gene expression makes a comparison between the normal gene working and that of defective gene working. It is that difference that is significant for determining the change in any genetic makeup which is the onset of any disease. Apart from this, some of these tests are also used for breast cancer screening and chemotherapy.

As far as the results of tests are concerned, these could be positive, negative or uncertain. The positive results show the presence of the issue or disease whereas the negative result is all about no genetic change. In some cases, the negative result could be false as well. The medical situation determines the type of tests to be performed and how to be conducted.
