I'm wondering if anyone knew what Serum Inorganic Phosphate and if it is important in any way?
The reason I ask is that I noticed the two times it's been tested it has always been lower than the range
March 2015 - 0.71 [0.87 - 1.45]
Feb 2011 - 0.65 [0.87 - 1.45]
yewotc23,
Phosphorus is one of the essential minerals involved with Vit D (hormone) in maintaining calcium levels in a feedback loop with parathyroid hormone. It is tested when bone stuff is investigated as is an essential part of the whole osteoclast & osteoblast bone making & mineralisation process.
I’m not sure but think it correlates with Vit D. Are you low or very high in Vit D? Otherwise, if you’re eating a balanced diet, it could be absorption issues, common in Hashi sufferers.
There's no info in your profile. Do you have thyroid condition?
This info from Labtestsonline could be helpful :

There is also a reference at the bottom of the page to "Elsewhere on the web". I thought there were two links in that section, one before and one after the comma, but there is just one. It's written confusingly.
There are several versions of Labtestsonline and they aren't all the same. The link I gave above is to the UK version of the website. There may be more info in the Australian and US versions of the site :
labtestsonline.org.au/learn...
labtestsonline.org/tests/ph...
It's also worth looking at "Elsewhere on the web" on each link, since they don't all point at the same alternatives. The Linus Pauling site, mentioned in the US version of Labtestsonline, is very helpful for quite a lot of info on vitamins and minerals.
If you are low in Phosphates try eating a banana every day. Do that for about a month then get the same blood test. If phosphates have risen then problem solved, if they are still low then - back to the drawing board.
Are you sure about bananas?
This linked document says it is classed as a low phosphorus food!

You know, I did Google bananas before I posted to make sure I wasn't thinking too much of Potasium and it did mention Phosphorus. But now I think about it more bananas are not the first thing that comes to mind for Phosphorus, rather fish and sea food in general - so, sorry yewotc23, forget bananas, think fish. Thanks Helvella, good job someone is watching the store.
Low levels can indicate hyperparathyroidism so you need your calcium and parathyroid levels checked, all done at the same time.
LAHs helvella bantam12 So I have found out that I am deficient in Vitamin D with a level of 14 - loading dose has been prescribed by GP. I am awaiting results of my bone profile, is it safe to start the loading dose now. Or wait until my bone profile is back?
Should I be concerned that my inorganic phosphate being low has never ever been mentioned to me by my old GP? I actually only found out when looking through past blood tests
The only safe answer I can provide is this: I don't know.
Sorry - but better not say anything than mislead you through my ignorance.
I would wait to see what your calcium level is, if high then taking VitD is not a good idea as it will send it higher. With low phosphate and VitD you really should have parathyroid levels tested.
bantam12 Thank you. If the calcium comes back as not being high, would you say to still get parathyroid levels tested?
excellent site to help with understanding all things 'parathyroid' parathyroid.com/
Calcium levels do fluctuate so it can happen that at the time it's tested it has lowered but will go up again, this is why it can take a long time to diagnose hpth because Drs assume if calcium is " normal" there isn't a problem. If your GP will test pth then you need calcium and phosphate done at the same time but pth is time critical so needs to be in the lab quickly. You may need several tests before you can definitely rule out Hpth.It took 2 years for me to get a definite diagnosis and it was hard work.
OK, this is just a logical thought rather than an opinion based on detailed knowledge. Problems associated with calcium and your bones is not a fast process. It takes a long time for bones to change their density or mineral make up. I would therefore wait until your bone profile is back. It is not as if your heart is struggling to beat and may fail within the next 24 hours, you have had this problem since February '11 and you are still here. I would recommend waiting, in addition you will then have a good baseline for your further medicinal trials.
LAHs bantam12 So my bone profile results are back:
Serum calcium level 2.42 mmol/L [2.2 - 2.6]
Serum adjusted calcium concentration 2.41 mmol/L [2.2 - 2.6]
Serum Inorganic Phosphate 0.90 mmol/L [0.8 - 1.5]
Based on that, would you say it's safe to start the Vitamin D supplement?
I can't say if it's safe or not, has to be your decision but in your shoes I would keep an eye on the calcium and get it tested again in a couple of months.
