Will stem cell transplants affect my test?

We often get asked if there is anything that can affect the sample collection rate or the results of the DNA testing. This is a much broader question than you might think and much more difficult to give a black and white response to. 

Our bodies are fantastic things and its difficult to say exactly what the effects of specific drugs or treatment can have on it. We know that different people can have the same treatment and experience different side effects and also the severity of those effects will vary. 

We are not aware that stem cell transplants should affect your ability to shed cheek cells for collection or that it should change the DNA since we look at SNP not STR markers in your sample. 

If you have any further concerns about past, present or future treatment and your results with us, please can we ask you to check with your healthcare provider as they will have far greater knowledge than ours and will, therefore, be able to give you advice that's correct for you.
