What it generally measures

CRP rises with many kinds of inflammation from many different causes — this test alone does not identify a specific cause.

Common units on reports: mg/L

Why people track it over time

Some clinicians review hs-CRP over time as one input among several. A single elevated or low value does not, by itself, indicate a specific condition.

Changes over time do not by themselves establish a diagnosis. Learn more

Questions you might ask a healthcare professional

Questions to bring

Illustrative

Ask what your clinician is using this result for in your specific case.

Mention recent illness, injury, or infection, since these can raise CRP independent of other conditions.
