What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

Protein/Creatinine Qualitative in Urine by Test strip

Protein/Creatinine

Creatinine to protein ratios by urine test strip provide a simple way to rule out significant proteinuria using a random urine sample. [PMID18987264] 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.
