Purpose Vitamin D to Anti- Rickets both steroid compounds showing activity, By acting on bone tissue secretary and the key to maintain serum Ca homeostasis. The blood level of vitamin D is the largest in D3 that the concentration of the metabolite is reflected in the holding state of vitamin D in vivo. Sunlight to change the 7-dehydrocholesterol in the skin and through the skin to D3, In the liver in combination with the D2 and D3 D4 changes. The Radioimmunoassay(RIA) method is measuring the D 3, the sensitivity can be measured also difficult trace substance to measure the normal test because it is very sensitive, but recently, a check is possible, for the Total D3 in Chemimicroparticle immunoassay(CMIA) or Chemiluminescent immunoassay(CLIA) measuring using microparticle RIA and CMIA(Architect i2000SR) / use the CLIA(DXI-800) method to compare and evaluate the correlation between the tests in the same test items. Materials and Methods Commissioned from January 2014 to March 2015 patients were enrolled in a total of 273 people. 29 out of 273 people conducted by RIA were compared with CMIA, 244 patients were compared with CLIA. Using reagents and equipment were used RIA(Diasource), CMIA(Architect i2000SR, Abbott Diagnostics) / CLIA( Unicel DXi-800, Beckman coulter). Results Correlation of the RIA and CLIA was a R2 = 0.1844 (y = 0.7303x + 3.9005), and the correlation of RIA CMIA is R2 = 0.2762 (y = 0.8862x + 4.56) respectively. (According to statistics, during the same period RIA is Deficiency 4.31%, Insufficiency 90.53%, Sufficiency 5.16%, was Excess 0%, CLIA / CMIA is Deficiency 17.02%, Insufficiency 75.91%, Sufficiency 7.03%, indicating the distribution of 0.03 % Excess) Conclusion Serum vitamin D and parathyroid hormone that show an inverse relationship, the level above which are not parathyroid hormone and vitamin D reduced the increase. The density is different for each study, at most 20 is reported to be the maximum between 30 ng / ml. In Korea it requires a proposed standard of vitamin D deficiency, reference to the WHO lack the case more than 10ng/ml, 20ng/ml and defined by the lack of, if not more than, the IOM, but looking at 12ng/ml or less to the normal to lack, at least 20ng/ml, the reference do not match the deficit under 20ng/ml, 21-29ng/ml relative lack between, was also defined as a sufficient condition for more than 30ng/ml. Although not statistically is between RIA and CLIA two ways to vitamin D levels change according to season match, when seasonally seen in summer as commonly known (April to September), winter (October to March) relative to the increase measured than it was found. Finally, the study on the correlation between the two methods have been expected to result in a consistent and apply the same view high reference value on the graph is difficult. However, there may be differences between the test equipment and methods, and could be especially the case of RIA method using an organic solvent is difficult to compare different methods and correlated view similar trend in vitamin D deficiency and quarterly aspect ratio.
