I had a blood test two weeks and the results came in and I spoke with my doctor and have low Vitamin D which I've had for awhile as I had blood test done by another doctor in June of this year and showed the same thing. I took my blood test home and saw I had low creatinine level at "0.77 based on a reference of 0.90-1.30 mg/DL" the doctor didn't say anything about the creatinie level and I didn't ask anything about it because I didn't notice it till I got home.
I looked at my blood work from June and the results are the same "0.77 but its based on a reference of 0.5-1.3" The blood test from June was done by Shiel lab while the recent one was done by BioReference Lab.
I have Crohns disease which has made me a hypercondriac.
Should I be worrying since the doctor didn't say anything and when I checked online most say normal range for a male is "0.5-1.1" "0.6-1.2" which would mean my creatinie level is normal. But this new lab has higher reference rate.
There is nothing wrong with low cr. It is simply a measure of how well your kidneys are filtering. If it is high, they are not working properly. If normal or low, the kidneys are working fine. Your body doesn't use creatinine for anything, it is simply a byproduct of muscle metabolism.
Hi I just saw your post about your creatinine level and Vitamin D level.
First of all I have kidney issues. I was born with 1 kidney and now have kidney disease of the right kidney.
My creatinine level as per the most recent blood work actually went up. I normally range from 2.0 2.1 level. A Rarity above. But it has now increased to 2.45 for the creatinine level.
And my Vitamin D level has been an issue for a while. According to my lab report the range should be 30.0 to 100.0 My results for Vitamin D was 11.6. I have had an ongoing issue with the Vitamin D levels being low.
So my doctor has me when it is low taking a prescription for Vitamin D. I take 50,000 units of Vitamin D. 1 tablet a week for 3 months. It seems to be a cycle with me.
When I saw my nephrologist this week he was concerned about the creatinine level. Also other numbers were elevated as well such as the protein level. I dont have numbers in front of me.
But there is reason for concern. My kidney seems to be functioning at about 30% and has been at that level for a while.
Not sure when I will require kidney dialysis. At this point with the elevated numbers my doc is having me redo the blood work in 3 months and then proceed from there.
PebbleBeach, just to put things in perspective for you, my nephrology department doesn't even begin to schedule you for dialysis teaching (about modalities) until you hit about 3.5 for cr. Depending on how you feel, it can be a long time before you need dialysis after that. I was at about 10 before I went on. Be resigned to frequent labwork, lots of visits to the doc, and levels going up and down. Try not to get too excited if the creatinine drops a bit, and don't get too depressed if it goes up.
