We have heard about urine DNA tests in the past, but what is the difference between transrenal DNA and the urine DNA that has been mentioned by others?
Urine is composed of two parts: first, a water solution containing salts and other soluble molecules including Transrenal DNA; second, sediment that is not in solution and includes cells that have been shed from the linings of the kidneys, bladder and urethra. When others refer to “urine DNA” tests, they are referring to DNA tests performed on the cells washed from the lining of the urinary tract into the urine. In addition, if the individual has a bacterial or viral infection in the urinary tract, DNA from these organisms has been commonly isolated from urine.
