If I have received a bone marrow transplant, could this affect my test results?

If you have recently received a bone marrow transplant, it is not advisable to take the tellmeGen DNA test. Please note that the saliva sample contains DNA from different cell types: cheek and mouth epithelial cells as well as white blood cells from saliva. When you receive a bone marrow transplant, your blood cells will contain DNA from the marrow donor, while your epithelial cells contain your own DNA. The combination of two or more sources of DNA often leads to errors in analysis. Even if the test is successful, it is not clear whether the results obtained are from your DNA or from the donor’s genetic material.
