3.01 is my latest creatinine number. It's a measure of kidney health and function. The lower the number the better the kidneys are, meaning the myeloma is under control. 3.01 is easily the lowest my creatinine has been since I was diagnosed. This trounces the previous best by 8%. So the myeloma is calm. My stress over recent changes could be pointless. Good news and a reminder to stay calm and listen to Berenson.
