Chemical Examination of urine | Urinalysis

Chemical examination of urine used to analyze the chemical property of urine like Protein, Bence Jones Protein, Glucose Test, Ketone Bodies etc

Chemical examination of urine used to analyze the chemical property of urine like Protein Test,  Bence Jones Protein, Glucose Test, Ketone Bodies(Ketones), Bilirubin, Urobilinogen Test, Porphobilinogen, Bile Salt Etc by biochemical method 


Chemical Examination of urine | Urinalysis


Chemical Examination:-Various methods are used for detecting abnormal chemical substances in the urine. Most of these methods are qualitative. The amount of the substance is roughly proportional to the intensity of the color.


The reagent strips are based on similar principles as traditional chemical tests. These test strips can either be single or multiple test strips with one or more test sites. They are plastic strips impregnated with appropriate reagents.

They are more convenient to use, less time-consuming, and more cost-effective. They are also space-saving, completely disposable, and need only a small volume of urine. 


It is important, however, to be familiar with the underlying principle in each test. In the following sections, some of the tests for detecting certain chemical substances in urine have been described in detail. here is the list of biochemical tests of urine given below
