Critical appraisal of oral calcium load test for indirect assessment of intestinal calcium absorption

Presence of impaired intestinal calcium absorption in chronic hypovitaminosis D and its change after cholecalciferol supplementation: assessment by the calcium load test

“…Inclusion criteria were: (i) age >18 years; (ii) availability for follow‐up for 9 weeks; and (iii) consent for undergoing vitamin D supplementation and assessment of intestinal calcium absorption by the ‘calcium load test’ (Pak et al. , 1975; Sakhaee et al. , 1979).…”

“…All had normal renal and liver test function tests. Inclusion criteria were: (i) age >18 years; (ii) availability for follow-up for 9 weeks; and (iii) consent for undergoing vitamin D supplementation and assessment of intestinal calcium absorption by the 'calcium load test' (Pak et al, 1975;Sakhaee et al, 1979). Subjects on drugs affecting bone mineral metabolism, such as calcium, vitamin D, glucocorticoids, anti-tubercular drugs, anti-epileptics and thyroxine, were excluded.…”

Diagnosis of Urinary Calculi

“…This can conveniently be achieved by a calcium tolerance test, of which various modifications are described in the literature HESSE 1979;BROADUS et al 1978;PAK 1978;SAKHAEE et al 1979;JOOST and PuSCENDORF 1980;KOHRI 1980;JOOST and PUTZ 1982;FUTTERLIEB et al 1984;HESSE et al 1984;KOHRI et al 1983;MATOUSCHEK and HUBER 1984;PFAB et al 1984;VONTOBEL et al 1984).…”
