These findings have increased the need for determining vitamin D status in a convenient and cost-effective way. In order to determine the better method for detecting vitamin D status, we have estimated blood vitamin D in three methods such as high-pressure liquid chromatography, chemiluminescent immunoassays and enzyme immunoassays. Method: Two hundred and sixteen subjects irrespective of age and sex were studied for blood vitamin D in all the three methods over a period of 2 years. Result: The statistical analysis showed that values of vitamin D obtained by chemiluminescent immunoassays (r = 0.978,展开更多

So, random urine calcium to creatinine ratio (Ca/Cr ratio) has been developed. But as the ratio varies worldwide, reference values of the parameter in paediatric population are not developed. To determine reference value, the present study was conducted in healthy paediatric population in Burdwan district, West Bengal. This study was performed on 693 healthy paediatric subjects, aged between 3 months to 18 years and divided into five groups. Early morning non-fasting urine samples from all study groups were analyzed for Ca/Cr ratio. A negative correlation was observed between age and urinary Ca/Cr ratio, but there was no significant difference of urinary Ca/Cr ratio between two sexes. Considering 97.5th percentile of the underlying distribution of values as the upper limit of reference range, upper reference values of urinary Ca/Cr ratio for age groups展开更多

In order to determine the better urine sample for detecting ACR, we estimated ACR in three modes of urine sample. Two hundred patients of uncontrolled diabetes mellitus with proteinuria irrespective of age and sex were studied for urinary ACR in all the three types of samples over a period of 2 years. The statistical analysis showed that first morning ACR (r = 0.999, p > 0.001) of the subjects was more significantly correlated with their 24 hour urine sample ACR than spot urine (r = 0.995,展开更多
