high vitamin D levels??

[rhesp1212]

I just spoke to DSs allergy specialist and his Vitamin D levels were double the normal high, and his calcium levels were within the normal range. This seems odd to me since my DS eats absolutely no dairy or calcium supplemented foods because he basically can only eat spelt, strawberries and tuna steaks...he reacts to everything else! She told me the actual number and I didn't write it down. He is on a multivitamin (Nano VM), but it's not 100% complete except for the vit. D. But, I'll be honest, half the time I forget to give it to him.

Anyone know what this means??? Is it okay for his vit. D to be that high?? The dr's reason was "he must have stores somewhere". Right! He's only 2

1,25 or 25 OHD?

[rhesp1212]

hmmm....I'm not positive, but I do remember the lab order saying 1,25 dyhydroxy.....vitamin D. I remembered the number she gave me. Normal high range is 70 and his actual number was 140

The wrong test was done to determine correct vitamin D levels.

Calcitriol (1,25(OH)2D3 or 1,25D3)Calcitriol (1,25-dihydroxyvitamin D) is made from calcidiol in both the kidneys and in other tissues and is the most potent steroid hormone derived from cholecalciferol. Calcitriol has powerful anti-cancer properties. It is sometimes referred to as the active form of vitamin D. Calcitriol levels should never be used to determine if you are deficient in vitamin D.

You need 25 OH D tested.

I do not know what high 1,25 D levels mean. I've only heard it referred to being high while the 25 OH D is low in Lyme disease.

Well, I'm not sure if that was the test they ran or not...I'll call on Monday and find out for sure. If the correct test was run, what does it mean if the level was that high? My dr. just said he has plenty of vit. D

1,25 is the active form of D, while 25 OH D is the storage form. Vit D is activated when the diet is low in calcium, to help you absorb that calcium better. It also interacts with cells, though, turning on cell processes via calcium ion channels. Assuming I know what I'm talking about here , increasing calcium in his diet (fish bone broth?) should bring the number down.

[JaneS]

So Whome you are saying that if his activated D is high that could be a sign that he is low in calcium? Which would make sense if he doesn't have a good source in diet.

OP,
Standard blood levels of calcium do not mean that his diet is adequate in calcium... the body will take from the bones and teeth to keep the blood levels of minerals normal as to prevent seizures, keep heart and brain running etc.

Wow, good information......I hadn't even thought about his body taking it from his bones and teeth to meet his needs. Although it makes total and complete sense. Kind of scarey!! So why do they even check calcium levels?!?!?

I guess I should also look into maybe finding a good calcium supplement for him to add in addition to what he's getting already. How long would it take to see a difference in his numbers. Any idea how much calcium he should be getting a day for adequate bone development, etc.?? He's 2 and weighs 30 pounds.

I finally convinced the dr. to check some of his other vitamin levels to make sure that they are adequate. Especially B12 and folic acid levels. They are also checking vit. A, zinc, magnesium and copper.
