Genetic Testing


Genetic testing involves lab tests to identify changes in chromosomes, genes, and proteins. The results of a genetic test help detect genetic issues, disorders, conditions and rule out the chances of developing or passing them on to the next generation.

Over 2000 genetic tests are in use at present and more are expected to be introduced soon. Some of the common methods of genetic testing include:

Chromosome Testing

These tests help analyze the long lengths of DNA and check for large scale genetic changes, For example, the generation of an extra copy of chromosome to cause genetic modification.


Biochemical Testing

These type of genetic tests are used to study the amount and activity level of proteins. Any abnormalities indicate changes to the DNA that would result in a genetic disorder.

Diagnostic Testing

These tests are used to identify diseases in a patient. The findings through these diagnostic tests help in making treatment-related decisions and choices.

Predictive and Pre-Symptomatic Testing

This kind of testing is used to detect gene changes that promote the chances of disease development. Results from these tests are helpful in informing decisions about lifestyle changes and healthcare.

Companion Diagnostics

These include Vitro diagnostic devices or imaging tools to provide information regarding the safe use of a therapeutic product for a patient, based on his/her DNA structure.

Carrier Testing

This testing technique is used to detect disease-causing genes among patients. Carriers of these genes may or may not reflect signs of carrying such disease, but have the ability to pass on the same to the next generation.

Prenatal Testing

This testing is carried out during the pregnancy period to help identify diseases or disorders in the fetus.

New-born Screening

This type of testing is used to test new-born babies, just one or two days after their birth to identify diseases that may cause problems with their health and growth.

Pharmacogenomic Testing

This type of testing provides information on how a patient’s body is reacting to the medicines prescribed to him. The idea behind this testing is to ascertain medicines that work best according to the patient’s genetic structure.

Research Genetic Testing

This type of genetic testing is used to learn about the contribution of genes towards an individual’s health and disease. The results may not be directly helpful to the participants, but they surely help researchers expand their understanding of the human body issues.

The ongoing interest in personalized medicine and research on the human genome has led to an increasing volume of genetic testing procedures for the clinical laboratories.
