CGT

CGT-Compatibility Genetic Test
The CGT test conducted at our centre can scan for over 300 genetic diseases from different groups and 1600 mutations that cause diseases (genetic coding deformities) in one test.

The physical appearance and health condition of the people donating the eggs and the genetic diseases that they may carry are the highest cause of interest and concern in egg donation practices. Many IVF donation centres in the area state that they conduct genetic screening tests (thalassemia, cystic fibrosis etc.) at European standards for commonly observed genetic diseases in the egg donors. However much these tests are declared to be a genetic screening test, they are only a blood test rather than a gene level test. Therefore, these are not tests that can clearly answer the most common questions such as ‘’How safe is the egg that I am receiving? Can an unknown genetic disease occur in our child caused by the donor? How carefully are the donors tested for possible genetic diseases?’’

Today, there are thousands of genetic diseases that couples who are treated or donors do not even know they have and until recently, it was not medically and technically possible to scan for these diseases. Now it is possible to scan for over 300 known genetic diseases with the CGT test by taking one sample of blood.

What is a CGT Test?
As it is known, many developments have been made recently in the field of genetics, particularly in mapping out peoples’ genetic map and predetermining genetic mutations (genetic coding faults in the DNA) that can cause diseases.

A simple blood sample taken from an individual for a CGT test can determine if the patient has one of over 300 genetic diseases and 1600 disease causing mutations (faulty genetic coding).

The genetic screening services developed with classical methods can only look for a few gene deformities at a time, whereas the CGT test can look for hundreds of genetic diseases. Also, the cost for this screening is less than the screening of just one gene conducted in the past.

How is the process conducted?
When you apply to our hospital for an egg donation, you can conduct the donor selection process according to physical appearances by selecting a donor from the pool of donors that have had a CGT test.

The donors chosen from the pool of donors that have not had a CGT test can then be called in to take a blood sample that is sent to the genetic centre for testing. The evaluation and testing of a blood sample taken for a CGT test can take 2-4 weeks.

Is a CGT Test only used in Egg Donation Treatments?
The CGT test that we offer at the Near East University IVF Centre is not only used for egg donors, but also for the couples who are having IVF treatment with their own sperm and eggs to determine any genetic diseases that they may pass on to their child.
Thanks to this test, genetic separation is used to help couples have healthy babies regardless of consanguineous marriages.
