CRP Test (C-Reactive Protein) in California
Below is a plain-language overview of the crp test (c-reactive protein). A C-reactive protein (CRP) test measures the amount of CRP in your blood. CRP is a protein your liver makes when there is inflammation somewhere in the body. Doctors order it to help detect or monitor inflammation from infection, injury, or chronic conditions. This page covers the crp test (c-reactive protein) for people in California, in Pacific, from what it measures to how to arrange a draw.

A C-reactive protein (CRP) test measures the amount of CRP in your blood. CRP is a protein your liver makes when there is inflammation somewhere in the body. Doctors order it to help detect or monitor inflammation from infection, injury, or chronic conditions.
What it measures
- C-reactive protein (CRP) — The main marker; higher levels generally mean more inflammation.
- High-sensitivity CRP (hs-CRP) — A more sensitive version used to assess cardiovascular risk.
- Reference range — The lab's expected range for a person without active inflammation.
Who it is for
A clinician may order a CRP test when you have symptoms such as fever, pain, or swelling, or to follow a known inflammatory condition. It is also sometimes used as part of heart risk assessment.
Preparation
No fasting is usually required for a standard CRP test. Tell your clinician about any recent illness, injury, or medications, since these can affect the result.
Results and what they mean
Results are reported as a number, often in milligrams per liter (mg/L), along with the lab's reference range. A clinician interprets your result together with your symptoms, history, and other tests. This is general information, not medical advice; discuss your results with a qualified healthcare professional.
Requesting the CRP Test (C-Reactive Protein) in California
Order online, choose a certified collection site in California, and review results through a secure portal. No referral is required, and orders are processed confidentially. With coastal metros, inland towns, and rural counties with very different access to testing, it pays to schedule your collection in advance.
Frequently asked questions
Do I need to fast for a CRP test?
Usually no. A standard CRP test does not require fasting unless your clinician orders other tests at the same time.
What can cause a high CRP?
Infection, injury, autoimmune conditions, and other inflammatory states can raise CRP. A single result does not identify the cause.
Can CRP tell me if I have a specific disease?
No. CRP shows that inflammation is present but not where it is or what is causing it.
How long until I get results?
Typical turnaround is 1 to 3 business days, though it may vary by lab.
