Does having an organ transplant affect home genetic testing?

My relative wants to take a 23andMe DNA test, but he has a heart and a kidney transplant (from 5 years ago). I have read about the possibility of chimerism (which I understand to be the presence of two sets of cells) in transplant recipients, and I am wondering if such a condition would affect the saliva-based DNA testing of 23andMe? And also, how common is this condition in transplant patients? Is there only really a pretty small chance that this will affect his test?
