Serum CRP Test at Chughtai Lab

A Serum C-Reactive Protein (CRP) test is a blood test that measures the level of C-reactive protein, a substance produced by the liver in response to inflammation. CRP is one of the most sensitive inflammatory markers in the body and rises rapidly when there is an infection, injury, autoimmune disorder, or tissue damage. While the test does not identify the exact cause of inflammation, it helps healthcare providers determine whether significant inflammation is present and monitor how well treatment is working.

Doctors commonly recommend a Serum CRP test when patients have symptoms such as fever, unexplained fatigue, persistent pain, joint swelling, or signs of infection. The test is also widely used to monitor chronic inflammatory diseases such as rheumatoid arthritis, inflammatory bowel disease, lupus, and certain bacterial infections. In hospitalized patients, CRP is often used to assess disease severity and monitor recovery.

At Chughtai Lab, the Serum CRP test is performed using advanced automated laboratory analyzers that provide accurate and reliable results. With experienced laboratory professionals, stringent quality assurance protocols, and a nationwide network of collection centers, Chughtai Lab delivers dependable diagnostic services across Pakistan.
