Can somebody tell me why CKD stage 3a or 3b is no big deal?

@windyshores I urge you to talk with your nephrolgist about the nuclear study. Why would Mayo and other major hospitals use contrast that would harm the kidneys for a kidney function test? A CT scan uses a different dye not suitable for CKD patients. @looplu79
You are correct that the answer lies between the 2 common tests as a formula is reached by the National
Kidney Founation that nephrologists use. Much of the measurement that a nephrologist also observes is the trend of the sodium, phosphorous, and potassium levels when comparing the 2 eGFR tests. For example, if you have a eGFR creatinine score of 45 and a Cystatin C score of 23, a nephrologist would give "slightly" more relevance to the Creatinine score if sodium, potassium, and phosphorus levels had a normal trend. That is why the nuclear test is so helpful.

MY eGFR is stable at around 40. If it drops again I will certainly make an appointment. I did a CT with oral uranium and got really sick, but not necessarily due to kidneys (it wasn't investigate).
Cursory googling would seem to say that a nuclear kidney scan is fine but it may be more complicated than that https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8380202/ I need to look into it further.
I have been told the creatinine based eGFR is affected by all kinds of things: hydration (of course), exercise, low blood pressure, low ejection fraction (heart), muscle loss etc. and that the Cystatin C is more stable. But yeah, my true GFR is probably around 45.
I have a 20% dose of Reclast with one hour IV hydration and infusion over one hour. Normal dose is 5mg over 12 minutes I believe. I wish I could still take my NSAID!
