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.

Status: ACTIVE
Order vs observation: Both
Method: High sensitivity

What it does not mean

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

Key facts

C reactive protein [Mass/volume] in Blood by High sensitivity method
C reactive protein
This term refers to point of care (often CLIA waived) testing in a clinical or lab setting for the quantitative measurement of C reactive protein (CRP) in whole blood. This term was created for, but not limited to, Mitsubishi Chemical Medience's PATHFAST® hsCRP test kit. For high sensitivity CRP (hsCRP) testing on serum or plasma specimens, see LOINC 30522-7.
