What does a test tube chromosome test examine?
Disease description:
Because they do not want to have children naturally, some people choose in vitro fertilization (IVF). During this process, chromosomal testing of the test-tube embryos is required. Many people want to know what aspects of the embryos are examined through chromosomal testing.

Chromosome testing in test tubes is an important part of assisted reproductive technology. The main testing components include chromosome examinations for both partners and chromosome testing of embryos.
Chromosome testing for both partners involves drawing peripheral blood to evaluate whether the number and structure of chromosomes are normal, helping to identify risks of genetic disorders such as Down syndrome (Trisomy 21) and Turner syndrome. Embryo chromosome testing is performed prior to embryo transfer. A small number of cells are taken from in vitro fertilized embryos for chromosome and genetic testing, to confirm whether the embryos are chromosomally normal and free from genetic diseases, thus ensuring the safety of both the pregnant woman and the fetus. Testing methods include karyotyping and fluorescence in situ hybridization (FISH), among others, and fasting is required to improve the accuracy of results.
