Hey, I am currently seeing a Nephrologist in my home town and I am due for a follow up appointment on August 24th. I have been tested 4 times in the past year due to high levels of Creatinine. I am a 42 Year Old Male, 6’1, 185lbs and Caucasian. My Creatinine has been tested as 1.22, 1.25, 1.11, 1.34, 1.19. I take a 5mg Lisinopril and 10mg Celexa and exercise 3 days per week. On the two tests were I scored a 1.11 and 1.19, I reduced my protein intake from 125 grams down to around, 50-75. My GFR is running in the 50’s and 60’s depending on how the Creatinine is ranging. My doctor says that I am in Stage 3 CKD. I wonder though, I have had 3 Urinalyses over the time frame but my tests always show Negative for Albuminuria and Proteinura. I have now completly overhauled my diet to manage Sodium, Protein, Phosphorus, and Potassium. Should I seek a second opinion? AM I really in stage 3 and does it matter that my urinalyses keep coming back negative? What would your advice be?
The creatinine results that you describe are within the range of variation for the laboratory testing. The creatinine tests can vary between 0.1 and 0.15 up and down and this is just the normal variation in the accuracy of the … Continue reading →
Lately my creatinine went from 2.9 to 3.4 to 3.2 and more recently it shot up to 5.0 and a week later from 5.0 it went back to 2.9. Can you tell me what’s going on with my creatinine?
I am unable to make a specific diagnosis based on the information that you present. These sudden changes need to be reviewed by your nephrologist. You may require some adjustments in your medication if there are remarkable changes in your … Continue reading →
My husband gets blood work done every 6 months for the last 20 years due to a pituitary adenoma. His Comprehensive Metabolic Panel has always been normal until 2 years ago. His creatinine went from a 1.21 in January 2015 to a 1.46 in August 2015. He had a 24 urine test done in November 2015 and it showed normal kidney function. The doctor said kidney function was 110%. Since then these have been his creatinine results – (range 0.60 – 1.35mg-dl) 11/2015 – 1.33 1/2016 – 1.22 10/2016 – 1.39 12/2016 – 1.29 5/2017 – 1.37 All other results with the panel are normal. My question is – are these fluctuations anything to be concerned about? His diet hasn’t changed, all he drinks is water so he can’t be dehydrated (same amount all the time), exercise hasn’t changed either.
The laboratory values that you report for the serum creatinine on your husband are not different from each other. These values are within normal laboratory variation for the serum creatinine test. There is a natural loss of kidney function with … Continue reading →
My father is 75 with CKD and diabetes. Recently he has been treated with corticosteroid and antiviral for Bell’s palsy. Now his creatinine level has raised up from 3.13 to 3.35. Now doctor prescribed acetylcysteine 600 twice a day for 7 days. Is that gonna work anyway to lower/stable the creatinine level?
I am not sure why there has been a slight elevation in the serum creatinine. This is a very slight increase and my not be significant. The use of corticosteroids in this situation will cause the diabetes to be much … Continue reading →
I read that “creatinine clearance” is another good indicator of kidney function. I am 57 years old. Weight is 307 pounds. Creatinine level is 1.63. Can you tell me my creatinine clearance and what it indicates to me?
The creatinine clearance is another way to estimate kidney function. It is based on the clearance of a metabolite of muscle called the creatine, that is then converted into creatinine and eliminated by the kidneys. This can be done by … Continue reading →
I was a live donor for my ex-husband and so my kidney functions are checked regularly. About three months ago my creatinine level through blood test was .52. My last test a week ago was 1.06. It’s more than doubled in just three months! What can I ingest that will have a positive impact on my kidney function and hopefully bring this level back down? I have already stopped drinking tap water, which is full of chlorine and other toxins, and switched to spring water bottled at the source. No pork ever. I eat mostly fruit and vegetables. I recently stopped eating these out of the can, just in case of chemicals, and switched to fresh. About the only meat I eat is lean boneless, skinless chicken breast grown organically and flash frozen. I think if I don’t put poisons in my body to begin with, my kidney won’t have to work so hard. At 61 years old is there any other ideas you may have?
A serum creatinine test of 0.52 milligrams per deciliter (mg/dl) seems a bit low for someone with only one kidney. I suspect that this test may have been in error. The level of 1.06 seems more believable. The goal of … Continue reading →
My U Creatinine number keeps climbing, What is the difference between U Creatinine and Creatinine? I find this a bit confusing.
The urine creatinine (U creatinine) is a measure of how concentrated your urine is and does not measure kidney function. The serum creatinine is used to estimate kidney function. The urine creatinine is only used to measure the concentration of … Continue reading →
My father is a CKD patient for last 10 years. His current biochemical profile is urea-202 creatinine-9.6 sodium-128 potassium-4.5. He is on antihypertensive drugs and passes 2 liters of urine/day. Intake is restricted to 1 liter. No respiratory distress, lack of appetite, drowsiness, or vomiting. Is it time to initiate dialysis?
I am unable to make a recommendation for dialysis without performing a complete history and physical examination. The decision should be made by a nephrologist who can consult with and examine your father.
My mother is a diabetic and kidney function test serum urea is 50, serum creatinine is 0.8. Is there any problem with kidney?
I am unable to make a diagnosis of kidney disease based on the information that you present. I suggest that you visit our web site and use the equation for estimating the glomerular filtration rate (eGFR). I also suggest that … Continue reading →
I’m a 22 year old female. I visited my GP with symptoms of fatigue and hypertension. I was diagnosed with coeliac disease three years ago and lead a healthy lifestyle. Through my creatinine measurements my eGFR has gone from 102 (creatinine 67) in 2015 to 84 (creatinine 79) at present. Is this something I should be concerned about? Does creatinine vary like this naturally?
The results that you quote are within the usual variability of laboratory testing. Unfortunately, our estimating equations and the laboratory testing cannot reliably tell the difference between an estimated glomerular filtration rate (eGFR) of 84 and 102 milliliters per minute … Continue reading →
