Book CRP Test Online

A CRP test helps:

● Detect acute or chronic inflammation
● Identify bacterial infections
● Monitor autoimmune diseases such as rheumatoid arthritis or lupus
● Evaluate recovery from infection or surgery
● Assess risk of cardiovascular complications when used as high-sensitivity CRP

Early identification of inflammation allows timely diagnosis and appropriate treatment.

A CRP test is recommended for individuals who require reliable inflammation assessment with convenient home sample collection and timely reporting.

You may consider booking your CRP test with SecondMedic if you:

● Have persistent fever without a clear cause
● Experience joint pain, swelling, or stiffness
● Have suspected bacterial infection
● Are monitoring autoimmune or inflammatory disorders
● Need follow-up testing after surgery or treatment
● Prefer certified lab testing with doorstep collection

SecondMedic facilitates CRP testing through NABL accredited laboratory networks that follow standardized quality control procedures, ensuring accurate and clinically reliable results.

The CRP test primarily measures:

C-Reactive Protein Level  

This indicates the degree of inflammation present in the body.

In certain cases, doctors may recommend:

High-Sensitivity CRP (hs-CRP)  

A more sensitive version used to assess low-grade inflammation and cardiovascular risk.

The test involves a simple blood sample collected from a vein and processed using standardized laboratory analyzers.

Normal CRP values typically are:

● Less than 1 mg/L – Low risk or minimal inflammation
● 1–3 mg/L – Moderate risk (in cardiovascular assessment context)
● Above 3 mg/L – Elevated inflammation
● Above 10 mg/L – Suggests significant acute inflammation or infection

Normal ranges may vary slightly depending on laboratory standards. Clinical interpretation should always be done by a healthcare professional.

Fasting is generally not required for a standard CRP test.

However, if the CRP test is ordered along with lipid profile or other metabolic tests, fasting may be advised. Always follow your doctor’s instructions.

● No special preparation is usually needed
● Inform your doctor about ongoing medications
● Stay hydrated before sample collection
● Avoid intense exercise before testing if possible

The blood collection process typically takes only a few minutes.

CRP testing performed in NABL accredited laboratories follows standardized calibration and quality assurance protocols.

Automated immunoassay systems ensure precision and reproducibility. However, CRP is a non-specific marker of inflammation. Elevated levels indicate inflammation but do not identify the exact cause. Additional diagnostic tests may be required for definitive diagnosis.

The CRP test price in India generally ranges between ₹400 to ₹900 depending on the city, laboratory network, and whether high-sensitivity CRP is included.

The price usually covers:

● Blood sample collection
● Laboratory processing
● Digital report delivery

Home sample collection may be included in select cities at no extra charge.

CRP levels may increase in COVID-19 infection due to inflammation, but the CRP test does not diagnose COVID. A specific RT-PCR or antigen test is required for confirmation.

Both CRP and ESR measure inflammation. CRP responds more quickly to changes in inflammation, while ESR may take longer to rise and fall. CRP is generally considered more sensitive in acute conditions.

Chronic stress may contribute to low-grade inflammation, but significant elevation in CRP usually indicates infection, injury, or inflammatory disease rather than routine stress.

Yes, CRP levels can change rapidly depending on the underlying cause. They may rise within hours during infection and decrease once inflammation resolves.

Not necessarily. Mild elevations can occur with minor infections or temporary inflammation. Persistently high levels require medical evaluation to determine the cause.

Yes. Obesity is associated with low-grade chronic inflammation, which may result in mildly elevated CRP levels.

Repeat testing depends on the medical condition being monitored. Your doctor may recommend follow-up tests to track inflammation over time.

Yes. The CRP test is a routine blood investigation and is safe for individuals of all age groups, including elderly patients.
