Murexide test a) What is the clinical significance of this test? b)To what is the color production due to? c)In what pathological conditions is the elimination of uric acid increased?What is Hemin test and Benzidine test?What are the precipitates that were produced during the calcium and chloride ion test when it comes to Analysis of Blood? Write the equations involved clearly and easily understandable.
- A sample from a 65-year-old man was brought tothe lab at 9am from a private clinic. Serumpotassium is 8.5 mmol/L. The test was repeatedand the same result is obtained. All laboratorychecks have been carried out and the result isanalytically valid. The doctor is called via telephoneand he reveals that the sample was taken at 4pmthe previous day by the nurse. a) Comment on the value of potassium obtainedb) What could possibly be the cause for such resultsobtained?c) What course of action would you recommend?Analysis of the pathological constituents GIVE THE FOLLOWING: a. Name of Test/Test Reagent b.
