C-reactive protein (serum/plasma) concentration by nephelometry
This test measures the level of C-reactive protein in your blood, a protein produced by your liver in response to inflammation.
["CRP helps doctors assess inflammation, often used to monitor conditions like infections or autoimmune diseases."]

Why Is This Test Done?
Your healthcare provider may order this test to check for signs of inflammation, monitor chronic conditions (such as rheumatoid arthritis or heart disease), or evaluate symptoms like fever, joint pain, or swelling. It can also help determine if an infection is present or if your body is overreacting to an illness.
What to Expect Before the Test
No special preparation is usually needed. You may be asked to fast for 8–12 hours before the test if it’s part of a broader metabolic or liver evaluation, but this is not always required. Bring any medications you’re taking to your appointment.
During the Test
A healthcare professional will draw blood from a vein in your arm. You may feel a slight pinch, but the process is quick. The blood sample is then sent to a lab for analysis using a nephelometry method, which measures how much light scatters from the protein in your blood.
What the Results Mean
Results are reported in milligrams per deciliter (mg/dL). Higher-than-normal levels may indicate inflammation, infection, or other health concerns, while lower levels may suggest reduced inflammation. Your doctor will interpret the results in the context of your medical history and symptoms.
Reference range
Negative for Candida auris (no growth detected). Reportable as Detected or Not Detected.N/A
No special patient preparation required. Collect specimen from suspected site of colonization (typically axilla, groin, nares) or infection (blood, urine, wound) prior to antifungal therapy when possible.
