98121-7Protein/Creatinine Qualitative in Urine by Test stripActive

Term Description

Creatinine to protein ratios by urine test strip provide a simple way to rule out significant proteinuria using a random urine sample. [PMID: 18987264]
This term is used to report ordinal results for the urine protein to creatinine ratio by test strip. Depending on the manufacturer, results may be reported as normal/abnormal, or normal/1+/2+, where abnormal and 1+/2+ indicate an elevated protein to creatinine ratio.

Part Descriptions

LP15838-3   Protein
Protein testing is performed to evaluate and monitor liver and kidney function and to detect and diagnose early kidney damage and various other diseases. Elevated protein levels may also be due to an infection, medication, vigorous exercise, or emotional or physical stress. Body fluids contain many different proteins that serve diverse functions such as transport of nutrients, removal of toxins, control of metabolic processes, and defense against invaders. Testing for protein levels may be done as part of a routine physical, a pregnancy workup, in cased of a suspected UTI, as part of a hospital admission, or to evaluate kidney function.

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
