The urine test strip consists of semiquantitative determination of a series of parameters (leukocytes, erythrocytes, nitrites (bacteriuria), specific gravity, glucose, protein, bilirubin, urobilinogen, ketones, pH) using a corresponding test strip. This analysis is most commonly used to identify possible kidney-urinary tract infections, but is not limited to the previously mentioned. In addition to changes in the kidneys and urinary tract, it also provides information on the metabolism of glucose and bile ducts. The result of the analysis often allows locating the disease process and assessing its extent as well as the effectiveness of the treatment.
The preferred material is the primary morning mid-groove, in the absence of this option, random urine. The morning urine sample must be preceded by a 8-hour fasting, and at least four hours elapsed from the previous urination (for the presence of micro-nutrients to reach the minimum amount required for nitrite testing).
In addition, you can determine the urine albumin and the albumin and creatinine ratio. Albumin is a protein in the blood that usually gets to the urine at a minimum. Even a slight increase in the level of albumin in the urine may be an early indication of chronic kidney disease in case of some people, especially those with diabetes and high blood pressure. If a physician suspects kidney disease after a urine test, a repeat urine test is performed to determine the albumin, and blood creatinine is determined and glomerular filtration rate (eGFR) is calculated.
