Creatinine is 1.3 and GFR is 49, do I have kidney disease?
Creatinine is 1.3 and GFR is 49, do I have kidney disease? Everything I've read indicates yes, and I'm waiting on results from further tests, but I'm wondering if anyone is aware of factors that can cause false readings for these tests? I'm super active and lift weights 6 days a week (not a body builder by any stretch) and wondered if the muscle is throwing off the test numbers?
Anyway, I'm not sure about my BMI to be honest, but I am a 37 year old, caucasian woman who is otherwise healthy. I weigh around 168 pounds but I am muscular from the recent heavy work-outs and my past life as a competitive swimmer and athlete for 12 years. My biological father (I was adopted) died of kidney and liver cancer so there MIGHT be a family link to kidney issues, but that is my only risk factor.
I'll know more about the other test results, hopefully on Monday, but in the meantime it is all making me a bit uneasy. One year ago my creatinine level was 1.1 and now it is 1.3. According to my doctor, when the GFR test was done for the first time ever, this October, I was at 54 and when it was re-tested in November it had dropped to 49...in just a matter of weeks. I had been working out at Curves (not such a great work out) up until this October (worked out there for 1 year) and the first week of October 2007 I joined a new gym....since October 15th I've been in the gym doing strength training and cardio 6 days a week. Would that throw off my creatinine over the past year and cause such a huge change in my GFR???
I had a kidney panel blood draw last Friday and turned in my 24-hour urine sample on Monday...
