hey there momma, i had to scout around a bit to find the back story and re-read
lol nice to see those units!
The serum level of calcium is closely regulated with a normal total calcium of 2.2-2.6 mmol/L (9-10.5 mg/dL) and a normal ionized calcium of 1.1-1.4 mmol/L (4.5-5.6 mg/dL).
do you know if your test was total calcium, or ionized calcium? i suspect that your calcium food urges and your normal PTH level indicate that your 8.8 result is a total calcium one, and that you are on the low side for serum calcium. can you confirm the type of test you had? 8.8 total calcium with normal PTH should certainly put your mind to rest over the hypercalcemia issue.
and now, what then to do about your lingering high d3..
i wonder if calcium intake is a d3 regulator, boosting low d3 levels http://www3.interscience.wiley.com/jour ... 1&SRETRY=0
, and helping bring down high d3 levels.
i found a study that looked at calcium study and d3 receptors in the kidneys of rats. VERY INTERESTING.
At normal serum calcium levels, the administration of vitamin D resulted in a 5-fold increase in [1,25(OH)2D3] receptor concentration. In hypocalcemic animals, however, vitamin D did not change receptor levels
i suggest that you might be okay to take some supplemental calcium to help deal with the d3.
so what to aim for? i'm having a bit of trouble getting decent numbers for healthy controls in order to get a calcium target. but at least i can find a potential minimum (9) and a maximum (9.
In medicine, hypocalcemia is the presence of low serum calcium levels in the blood, usually taken as less than 2.1 mmol/L or 9 mg/dl or an ionized calcium level mm of less than 1.1 mmol/L (4.5 mg/dL)
the upper 'normal' range for serum calcium is associated with more disease - i read two studies; one put the cutoff at 9.8 and the other at 10.
optimal point inside that 9-9.8 range pending!
