3018311
The urea creatinine ratio will measure how much urea is in your blood as well as the ratio between urea and creatinine. When your body breaks down proteins, the liver makes urea and it is excreted from the kidneys. [1]
Reasons this test may be done include: [1]
- Severe dehydration
- To check for normal or abnormal kidney function
- Making sure those with kidney disease are not going into kidney failure
- Check the kidneys on medications that are toxic to the kidneys
The normal range for BUN/Creatinine ratio is anywhere between 5 – 20 mg/dL. [2] BUN/Creatinine ratio increases with age, and with decreasing muscle mass. [2]
In the OMOP vocabulary 3018311 is a Standard Concept that represents the measurement UREA NITROGEN/CREATININE [MASS RATIO] IN SERUM OR PLASMA
The recommended low and high values for each unit associated with 3018311 are below. These are not meant to be normal values. Rather, these are meant to be biologically plausible values. For example, it would be implausible to see a patient with a weight of 0 kg though a person could be 2.5 kg.
In the OMOP vocabulary 9074 is a Standard Concept that represents the unit MILLIGRAM PER MILLIGRAM OF CREATININE
0.001

The range .001-100 was chosen based on values seen in real world data. Althoug kindeys filter out most of the the ureaa nitrogen in the blood , small traces of stable urea nitrogen remain in circulation. [1] It's also noted that Creatinine is produced at a fairly constant rate. [1] There are a number of outliers seen in this measurement likely due to source data entry mis-types and/or meaurement mis-labeling. In the data reviewed more than 99% of data with this standard unit concept should be accounted for.
