Vitamin D deficiency is also common in women with polycystic ovary syndrome (PCOS), with the 67-85% of women with PCOS having serum concentrations of
25-hydroxy vitamin D (25OHD) <20ng/ml8.
(3) People with fat malabsorption and bariatric patients are barely consume fat-soluble vitamin D, and also people suffering from kidney related problem lose
25-hydroxy vitamin D, attached to the vitamin D binding protein through urine excretion.
25-hydroxy vitamin D (25(OH)D) is a fat-soluble vitamin that plays an important role in mineral and bone metabolism.
Participants were asked to undergo laboratory procedures that comprised (1) a blood work: 10 milliliter of brachial venous blood was sampled for calcium, phosphorus, alkaline phosphatase,
25-hydroxy vitamin D (25(OH)D), blood urea nitrogen (BUN), creatinine (Cr), and parathyroid hormone (parathormone), and (2) a 24-hour urine collection test for calcium, phosphorus, creatinine, and urine volume.
One of the common nutritional deficiencies among these groups of patients is secondary normocalcemic hyperparathyroidism (SNHPT) [1, 2, 4-7, 20, 21], characterized by low serum
25-hydroxy vitamin D levels, high PTH levels, and normocalcemia [22].
25-hydroxy vitamin D concentrations in serum were estimated by ELISA in HMC pathology laboratory.
Vitamin D and mortality: Individual participant data meta-analysis of standardized
25-hydroxy vitamin D in 26916 individuals from a European consortium.
Prevalence and significance of low
25-hydroxy vitamin D concentrations in healthy subjects in Delhi.
Zirie, the most accurate way to measure how much vitamin D is in the body is the
25-hydroxy vitamin D blood test.
Recently, it was reported that serum
25-hydroxy vitamin D level of <20 ng/mL was associated with UTI in children (7).
ABSTRACT: It is hypothesized that in humans decreased serum concentration of
25-hydroxy vitamin D (25-OH-vitD) may be able to promote weight gain.
