A rapid simple method for the direct determination of iron in serum is described wherein Ferrozine was employed as the color reagent. Copper, hemoglobin and moderate lipemia did not appear to interfere with the determination. A good correlatlon was obtaihed for serum iron values when proposed direct technique was compared to a conventional method.

As a part of the Quality Control Program 10 different chemistry items had been analysed and compared by means of the methods of X, Cusum and Average of normals. Of these methods the Cusum method was found to be most convenient and made us able to rule out early detection of discrepancies. However, the tendency of outlier, unrest trend and shift of the test data had been observed through the study.

In European countries or Japan they made an attempt for the standardization of assays in AST, AL T, ALP, CK, ill and GGT 10 years ago. For the actualization of the trial, they managed to succeeded in development of certified reference material and enzyme reference material. And they are now forecasting the unification of test results produced differently urder the respective situatons. Then, throogh the highly developed communication system, someone can access any test results whenever or whereever only if they want to. It means that we can expect much greater improvements in medical services through the information exchanges. In this study the authors tried to ascertain the interchangeability comparing the obtained results of the CK tests between two general hospitals. Fortunately, the data got in the internal QC programs came to fall within the normal tolerances. The reference intervals for the CK test were different according to the chosen reagents and the results from the pooled sear were also shown differently each other. However. from the two hospitals. we could get glucose K factors, upon which the measurements were obtained and compared. Using K factors we measured the CKs, then we mulply the CK values by correction coefficients. We could found that the two results were showing good coincidence in the comparison. The main purpose of the standardization of enzyme assays is the creation of a new unified value can be expressed differently otherwise. Using the standardizad values we can exploit the data everywhere, reduce the medical costs from repeated or duplicated tests, save the foreign exchanges preventing the diversification of import connections.

The thymol turbidity test of Maclagan has been shown to be of considerable diagnostic value in certain types of liver disease. Mac1agan have reported that the test was probably associated with an increase in r-globulin. Recant, Cohen and associates, on the other hand, have shown that the test depends on the presence of lipid containing fraction of serum globulin (ß-globulin fraction), than the r-globulin. The study had shown that the thymol turbidity is affected by changes of serum total protein, albumin, α1-g1obulin in low and ß-globulin, r-globulin, total lipid, total cholesterol, triglyceride and pre-ß-lipoprotein in high concentration. The status of thymol turbidity test in clinical laboratory should be determined since its application in the field has been argued.
