 Okay, good. Thanks, David. If you miss anything, call this number, 1-855-949-7234. Doc, I email in from Betty. She wants to know, how do you know if you have a kidney infection? Okay, that's a good test. You go into your doctor and just say, I just want to lab stuff. I want to test my urine to see if I have a kidney infection or if there's anything going on with my kidney, if there's any blood in it or whatever.
