C-Reactive Protein (CRP) Quantitative Blood Test

A C-Reactive Protein (CRP) Quantitative test is used to aid in the diagnosis of infections or diseases which cause inflammation.  CRP is a protein produced by the liver.  Higher than normal concentrations of CRP are often an indicator of infection or inflammation in the body.  This test can help determine if an infection is present but not the source of the infection.  Condition which can cause elevated CRP levels include but are not limited to Sepsis, Pelvic Inflammatory Disease, Arthritis, Lupus, Vasculitis, and Inflammatory Bowel Disease.

C-Reactive protein levels are often higher in people who have recently had a heart attack. This test may be used to help determine if a person has had a recent cardiac event.

A C-Reactive Protein test is typically ordered when it is suspected that an infection is present in the body.  This test may be ordered because someone is exhibiting symptoms or if they have recently had an operation or surgery to check if any infection is present.  It can also be ordered to monitor treatment for infections or inflammatory diseases by seeing if CRP levels are going down in response to medication.

This test is most effective at detecting elevated levels of CRP.  A C-Reactive Protein High Sensitivity test may be more appropriate for someone who is checking CRP levels to assess their risk for heart disease.  A CRP High Sensitivity test can detect lower levels of CRP which may indicate an increased risk for events like heart attack or stroke.

Turnaround for the C-Reactive Protein Quantitative test is typically 1 business day.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.


The C-Reactive Protein (CRP Test) Quantitative test has no fasting requirements.
