creatinine through spot urine

[vinadhun2]

Can anybody answer on following:

i never had protein in urine. As part of KFT , i got creatinine tested in blood and spot urine

One month back serum creatinine was 1.97 and through spot urine was 123

Now after following treatment my serum creatinine is 1.95 and throgh spot urine is 88

IS THIS BAD OR GOOD TO GET REDUCED CREATININE THROUGH SPOT URINE

You should pay more attention to your blood creatinine and your eGFR. That is what doctor's pay attention to. When your eGFR gets to be around 10 and single digits, it's time for dialysis.

I think I told you before that we all have creatinine in our urine and naturally the am ount varies by what you have been eating and if drinking an appropriate amount of water. There is a normal range for men 20 - 275 mg/dl. I am sure there is no worries if your urine creatinine is in that range. If your urine creatinine is lower than the last time you were tested, 123 and now 88. It really just means you ate a kidney friendly meal before you tested your urine and were hydrated. Yes, if above the range your doctor would worry.

No comment from my nephrologist regarding my urine creatinine values 44.7 most recent, 294.4 & 142.3 other values from this year. My blood creatine is stable because these values are within normal. Women normal range for urine creatinine s is 20 - 320.

Since your kidneys are filters, If your value was above normal, it may be a sign of more kidney damage. But then it would show up in your blood creatinine and your eGFR.

Once you have kidney damage it doesn't get better. Your change from 1.97 to 1.95 is normal. Now if your creatinine had jumped from 1.97 and now is 2.9, that would be a concern for your doctor & you. My doctor knows there can be normal variations. Your creatinine changes were to the hundredth which is probably normal variation. My lab values are always to the tenth of a percent not to the hundredth. When my creatinine changed from 1.8 to 2.1 & my BUN was 30, my doctor ordered a repeat of labs. It showed with the repeat that I was dehydrated the first time because my creatinine went back to 1.8 & BUN went down to 20 with the repeat.

Doctor's look at your blood creatinine, BUN, sodium, phosphorous, magnesium, etc to be able judge how your kidneys are doing. So much goes into kidney health that you cannot judge just from your urine creatinine values. This is just one element.

Many thanks for your detailed reply.

You are right that may be my spot urine creatinine values have come lower because I have started kidney friendly diet.

I am monitoring all values regularly.

Since 2019 all electrolytes are within normal limits, no protein in urine, BP is normal, No diabetes, cholesterol is within limits. Only blood Creatinine has been varying between 1.75 and 2.05.BUN, Urea, Uric acid all normal

My nephrologist has said not to worry this is due to old age.

I guess he is right.

Now I am 76

Remember as we all age our creatinine does rise. My husband is 74 and his creatinine is 1.7. Doctor told him not to worry also. He is not diabetic and BP with medication is fine.

Take care!

many reasons why creatinine rises in the body, old age, muscle deterioration, eating a meal high in protein etc. Creatinine in your urine is just fine, it shows your kidneys are filtering out the creatinine ,which is what they should do. Also a high blood creatinine is not a test for CKD alone, when I ate a large amount of meat my creatine shot up, a few days later it dropped back down.
