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.

What it does not mean

The code identifies the observation or test, not the actual result.

Key facts

Beta-trace protein [Mass/volume] in Ear fluid
Beta-trace protein
Ear fluid drainage is tested to see determine if the fluid is really CSF, endolymph or perilymph (CSF like) rather than serous or inflammatory fluid coming from the ear canal.
