title: Interference of Bilirubin in the Determination of Magnesium with Methyl Thymol Blue.
abstract: BACKGROUND
  Jaundice is a disease named for the yellow color of the skin. This color is the result of elevated levels of bilirubin in the blood serum. In Roma from Krusevac region in the last few years have seen the emergence of jaundice.
  
  
  METHODS
  In 80 of them (40 suffering and 40 from control group) were performed tests of numerous parameters in the laboratories of the Health Center in Krusevac. Magnesium was determined by spectrophotometry with methyl thymol blue, titanium yellow and blue xylidene. Bilirubin was determined by Jandrešek Grofov's method.
  
  
  RESULTS
  The results were within the expectations, in addition to magnesium which was determined with methyl thymol blue. In all patients suffering from jaundice concentration of magnesium (0.67 ±0.14 mmol/l) statistically was significantly lower than tested of the control group (0.91± 0.059 mmol/). There is no theoretical data to reduce the concentration of magnesium in serum as a result of jaundice. That's why we determined magnesium both in the control group and in sufferings with two methods as the titanium yellow, and xylidene blew. With these two methods we obtained results that were examined were within normal limits.
  
  
  CONCLUSIONS
  This has led us to conclude that the determination of bilirubin interferes with magnesium methyl thymol blue.
