My Dr. says my Vit. D level is low and I have the blood test results but I don't see it listed. Is it eGFR?

No, the .gfr test is for kidney function. I just recently got my Vit D results as well and it is 17 and I was told it should be 30 to 50. I have RA and we usually have low Vit D. So your disorder/disease may cause low levels. That is a good question for your doc.
They put me on 50,000 ut Vit D once a wk. It isn't anything to worry about but it does cause fatigue.
Hope this was helpful!
Wish you well

No, it isnt the eGFR. It should say Vitamin D 25-hydroxy and is usually ordered by a special test. It isnt in the metabolic panel like the eGFR is. eGFR is estimated Glomerular filtration rate and shows part of kidney function, how well your kidneys filter a waste called creatinine. Look in a different section of the bloodwork for the Vitamin D test.

It is wise to always ask for a copy of your blood tests so that you can see the answer to the question you are asking here. My blood test statement shows that my vitamin D 25-OH total is 16 and the the other column states that is "L" for low. The reason your Vitamin D levels are in your blood test resurlts is as follows. The reference range which is what it should be is 20. Then there is a notation on my statement that says: "The 2011 report from the Institute of Medicine recommends that nearly all individuals meet their need for vitamin D with 25 hydroxy vitamin D levels greater than or equal to 20 ng/ ml even under conditions of minimal sun exposure." So it seems after this statement on my sheet received from the Diagnostic Labs, it is a fact that we should be in the 20 or over range... it is strange that so many of us have low vitamin D levels and I wonder if the sun rays are no longer strong enough due to pollution/other problems.
I am taking a gel pill once a week and will be seeing my doctor soon to see how it is going for me.
Hope this helps.

Serum concentration of 25(OH)D is the best indicator of vitamin D status. It reflects vitamin D produced cutaneously and that obtained from food and supplements.
Any level <20 is deficient, but the latest research says:
Adjust supplementation accordingly to remain in the range of 35-55 ng/ml which is now considered optimal.
If you do not know your 25(OH)D levels, approximately 2000 IU is a reasonable dose of vitamin D to take until you can get your levels tested. You can assume your low, as a nation we are chronically low. And it's D3 you want to take in supplement form. I can't site my source as this is from being a clinical dietitian, and learning this through various lectures, webinars and research. I take 3000 IU Vit D daily and I believe when I first was checked I was around 20.
I agree with a post that I think was stating that due to scare of skin cancer, everyone went overboard with sunscreens. I remember growing up in the early '80's watching my mom
Sunbathe in baby oil. And she's perfectly fine. I rarely see melanoma in the hospital, but I am not going to undermine any cancer, ever. However, it's recommended we get 15 minutes of sunlight a day, without sunscreen. In my mind, what could be more dangerous, lathering up in chemicals to sit in the sun all day or soak in 15 minutes of glorious sunshine, chemical free. And I've often thought, what causes melanoma? The sun or the chemicals to protect us from the sun. I'm a little sun bunny though so I opt to soak in the rays and maybe I'll use SPF 4, if anything but it depends on skin type, genetics, etc. I'm Italian so my skin loves the sun. HOWEVER, just as we can go overboard with sunscreen, we can go overboard with Vit D. We want to treat but not over treat. :)
