## What does the C-Reactive Protein (CRP) test tell you?

General inflammation marker — elevated in infections, autoimmune conditions, and chronic disease.

C-Reactive Protein (CRP) is a protein produced by the liver in response to inflammation anywhere in the body. Unlike hs-CRP (which measures very low levels for cardiac risk), standard CRP measures higher levels associated with infections, autoimmune conditions, inflammatory bowel disease, and tissue injury. It's a general marker that indicates something is causing inflammation but doesn't specify the source.

**Clinical use:** Standard (non-high-sensitivity) C-Reactive Protein. Marker of acute inflammation, used to monitor infection severity, autoimmune flares, and post-surgical inflammation.

## Who should order it?

Anyone with suspected acute infection, monitoring an autoimmune condition (RA, lupus), tracking post-surgical recovery, or with unexplained fever.

## How much does a C-Reactive Protein (CRP) test cost?

A C-Reactive Protein (CRP) test costs $26.99 at TestWell — $32.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Hospital outpatient labs typically bill around $80.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.

| --- | --- | --- | --- |
| TestWell (drawn at Quest or Labcorp) | $26.99 | $32.99 | Includes the one $6 lab processing fee, charged once per order |

## Common questions about the C-Reactive Protein (CRP) test

### CRP vs hs-CRP — which should I order?

[hs-CRP](https://www.test-well.com/tests/hs-crp) measures the same protein but detects much lower levels — used for cardiovascular risk assessment (chronic low-grade inflammation). Standard CRP is for acute inflammation (infection, flare). Use hs-CRP for heart health, standard CRP for active illness investigation.

### How much does a CRP test cost without insurance?

TestWell charges $26.99 — vs $29 at Quest Direct and $50-$120 at hospital labs.

### Do I need to fast?

No fasting required.

### What's a normal CRP level?

<10 mg/L is the standard reference. <3 mg/L for cardiovascular risk monitoring (hs-CRP cutoff). >100 mg/L typically indicates bacterial infection or major inflammation.

### How fast does CRP respond to inflammation?

Rises within 6-8 hours of an inflammatory trigger, peaks around 48 hours, normalizes within days once the trigger is resolved. That makes it a useful real-time monitor for infection severity and treatment response.
