Glucose and ketone bodies should not be present in normal urine . However, glucose begins to appear in the urine ( glycosuria ) when glucose ( blood sugar ) exceeds 180 mg / dl. Ketone bodies which are produced in the body in the absence of insulin , blood glucose levels occur in more than 240 mg / dl . Their presence in the urine ( cetonuria ) is a warning , not being able to get treatment in diabetic cetocidoza . When ketone bodies in the blood increases , the patient receives a specific breath halitosis .
Method of measurement of glycosuria and ketonuria is similar to the strip . The results are compared with a standard color reference card . The metabolic balance of diabetes and its monitoring and dosing required ketones and glycosuria .
- The collection container
- strip for measuring specific glycosuria or ketonuria
- All color reference card standard
confirmation and verification of patient identity
patient explains the procedure , especially since the patient is newly diagnosed as diabetic. Patients with diabetes are known for a long time can be taught to harvest home alone .
check that the patient medication that could alter test results.
Before each test the patient is taught to not contaminate the urine sample
Wash hands and put gloves
required the patient to urinate , and then offered a glass of water and , after 30 -40 minutes are required to urinate again , in the second test will be performed by immersing the test strip that
required depending on the test strip will be kept in the urine sample according to the prospectus of use , and will be read and interpreted in relation to the reference card .
Special considerations :
determination of ketone bodies in urine helps in the differential diagnosis between the nondiabetic and diabetic coma and monitoring lipid metabolism .
