any one can answer my question please ! why in vitamin D intoxication we measure serum 25 (oh) D and not 1,25 (oh)2 D? And why in Sarcoidosis we measure Serum t 1,25 (oh)2 D? ANY HELP !
Because 1,25 has very short span of life. 25 is inactive one and this 1,25 is the active form. Obviously if you have low 25oh you are going to have low active vitamin D also when required. Its a complex mechanism.
Can anyone answer me I have from a very long time hypercalcemia (probably ca>10.50). And when i first got tested, it came as 10.40 with very severe vitamin D deficiency (only 4 nmol). After 6months of supplementation, now my vitamin D is 60 but my Calcium has risen to around 10.80. Is this a case of hyperparathyroidism ?
