Calcium Blood Test

[Spangle15]

Hi. Does anyone know who I can use to test my calcium and do an iron panel in a finger prick home blood test?

Thank you.

Are you in the U.K.

Medichecks do full iron panel test

Medichecks also do calcium test

Have you tested vitamin D

Low vitamin D linked to low calcium

Great, thanks SlowDragon. Yes, my vitamin D is good. I have secondary hyperparathyroidism, although no one knows why, although I’ve been told recently it could be caused by my HRT or low magnesium.

Very good website re all things parathyroid

Do you supplement magnesium or vitamin D

[Spangle15 in reply to SlowDragon]

Thank you. I supplement vitamin D but I’ve only just started magnesium as I didn’t realise it was so important until I joined this forum. Especially given I have osteopenia.

parathyroid.com/hyperparath... has been suggested (wrongfully) that low Vitamin D levels will cause normal parathyroid glands to hypertrophy and over-produce PTH... which in turn will cause the calcium to rise. This does not happen. Low Vitamin D levels will NEVER cause the calcium to increase above normal. Low Vitamin D does not ever cause a high calcium. It is possible, as shown on the graph above, that low vitamin D levels in patients with low-normal or low calcium levels will be associated with modest elevations in the PTH. But that's as far as it goes. Low Vitamin D will not produce a cascade of events that lead to high calcium levels in the blood. Remember, most patients with tumor-proven primary hyperparathyroidism will have LOW Vitamin D levels.

Interesting, my calcium is just under range and pth slightly raised. Maybe I need higher vitamin D than others. I actually had primary five years ago and had two adenomas removed.

What’s your most recent vitamin D test result

How much vitamin D are you currently taking

We often need higher dose vitamin D with thyroid disease

Is it mouth spray or tablets

Tablets and gels must be minimum 4 hours away from levothyroxine

[Spangle15 in reply to SlowDragon]

It was 111, last time, but it’s usually around 120. I take 5.000 IU (125mcg) about 2-3 times a week to maintain it. They are tablets.
