C-reactive protein (CRP) is a blood marker for inflammation produced by the liver. A simple blood test measures the level of CRP in your body. CRP levels can help diagnose acute and chronic conditions that lead to inflammation such as infections, arthritis, and heart disease. Inflammation has also been linked to severe COVID-19 infections, and monitoring CRP levels can aid in identifying potential complications. Understanding the normal range of CRP and how to control your levels can be crucial in managing various health conditions. In this article, you will learn about the normal range of CRP, CRP levels in COVID-19 patients and ways to control your CRP levels.

Acute or chronic inflammation in the body could be a response against multiple diseases, including viral infections like Covid-19. Look out for signs like abdominal pain, fatigue, chest pain, mouth sores, or joint pain. Symptoms like these indicate a possibility of inflammation in the body. Getting a CRP test allows you to get a confirmation and treatment to treat it on time. |

Normal Range of CRP Levels
In a healthy adult, a CRP value less than 3 mg/L is considered normal. The CRP values above 3 mg/L may indicate inflammation.
The degree of inflammation is often reflected in the magnitude of the CRP value, and higher levels may indicate more severe inflammation. However, it's important to note that CRP normal range levels can vary depending on various factors such as age, gender, and underlying health conditions. Therefore, it's important to interpret the CRP levels in conjunction with other relevant factors such as clinical symptoms, medical history, and imaging studies.
Different levels of CRP and their indications are tabulated below:
| S.No. | CRP Level | Inference | Description |
| 1. | < 3 mg/L | Normal | Indicates healthy adults |
| 2. | 3 mg/L - 10 mg/L | Normal or minor elevation | Observed in pregnant women or people with diabetes, depression, obesity, sedentary lifestyle, or smoking. It may also indicate the risk of cardiovascular diseases. |
| 3. | 10 mg/L - 100 mg/L | Moderate elevation | Observed in people with cancer, autoimmune disease, heart attack, and bronchitis. |
| 4. | 100 mg/L - 500 mg/L | Marked elevation | Observed in people with acute bacterial infection, viral infection, or trauma. |
| 5. | > 500 mg/L | Severe elevation | Acute bacterial infection |
High Sensitivity CRP (hsCRP)
A high sensitivity CRP (hsCRP) test is conducted to appropriately detect the levels of CRP that are below 10 mg/L. This hs-CRP test is often recommended for individuals who are at a higher risk of heart disease, as it can help detect low levels of inflammation that may not be picked up by a standard CRP test. The hs-CRP test is especially useful in predicting the risk of cardiovascular disease, as even low levels of inflammation can contribute to the development of heart disease over time.
The level of CRP in hs-CRP and their respective inferences are tabulated below:
| S.No. | hs-CRP level (mg/L) | Inference |
| 1. | < 1.0 | Low risk of heart disease |
| 2. | 1.0 - 3.0 | Moderate risk of heart disease |
| 3. | 3.0 - 10.0 | High risk of heart disease |
Regular monitoring of hs-CRP levels can aid in the early detection and management of cardiovascular disease, improving overall health outcomes.
CRP Levels in COVID-19
C-reactive protein is an essential biomarker in COVID-19 patients. This may be due to the overproduction of inflammatory cytokines during the infection. Higher levels of CRP were observed in patients with low oxygen saturation (< 90%) as compared to those with high oxygen saturation (> 90%). According to research studies, the levels of CRP in different groups of COVID-19 patients are tabulated below:
| S.No. | Patient Group | CRP Level (mg/L) |
| 1. | Hospitalized | 47.6 - 51.4 |
| 2. | Death | 100 - 113 |
| 3. | Recovered | 9.6 - 26.2 |
| 4. | Admitted to the ICU with GI symptoms and without GI symptoms | 15.7 and7.9 |
| 5. | Admitted to the ICU | 43.1 - 62.9 |
| 6. | Mild | 7.6 - 23 |
| 7. | Non-severe | 10 - 12.1 |
Ways to Reduce CRP Levels
With certain modifications in your diet and lifestyle, you can control your CRP levels and remain in CRP normal range. Certain steps that you can take to reduce your CRP levels are
- Weight loss: According to a study, decreasing the total body weight and fat mass by 5% can cause an effective decrease in the CRP levels.
- Optimistic approach: According to a study, having a negative mindset leads to increased CRP levels.
- Exercise: Daily exercise and an active lifestyle are essential to maintain an optimum level of CRP.
- Treat the underlying cause: To decrease the level of CRP, you need to target and treat the underlying disorder responsible for the elevated levels of CRP.
- Diet: Including food items like apples, bananas, avocados, beans, broccoli, sprouts, legumes, strawberry, pear, and whole grains can help manage CRP levels.
- Supplements and medicines can also reduce CRP levels in your blood. These should be taken only when prescribed by a registered medical doctor.
- Stress-reducing techniques such as meditation, yoga, and deep breathing exercises can also help in managing CRP levels.
- Avoiding smoking and limiting alcohol consumption is crucial to keep CRP levels in check.
- Proper sleep hygiene is also important as lack of sleep can cause inflammation and increase CRP levels.
- Consuming foods rich in omega-3 fatty acids such as fatty fish, nuts, and seeds can help reduce inflammation and lower CRP levels.
These lifestyle changes should be adopted as a long-term approach to manage CRP levels and maintain overall health. However, consulting a healthcare professional before making any significant changes to your diet or lifestyle is always recommended.
Takeaway
CRP levels are a key indicator of your health and help diagnose any inflammation or infection. However, it is important to note that increased CRP levels may not tell the exact site of inflammation or infection, and other diagnostic investigations may be required for the same. The levels of CRP reduce as the inflammation is treated. Hence, it serves as a very important prognostic marker. Lifestyle modifications also aid in decreasing the levels of CRP. You can better analyze your laboratory blood test reports now that you know about CRP normal range levels and what they indicate.
Also, if you are experiencing symptoms of inflammation or infection, or if you are at a higher risk of heart disease, it is recommended to get your CRP levels tested. Redcliffe Labs provides a reliable and hassle-free experience with their CRP Test. With quick and precise reports, reporting as per NABL ISO guidelines, free home sample collection, and free doctor's consultation, you can take control of your health and get the necessary medical attention in time.

A CRP level of 130 is elevated and indicates inflammation. While your rheumatologist may not be overly concerned, it's important to discuss your rising levels and any symptoms with your doctor. Consider lifestyle changes like a healthy diet and regular exercise to help reduce inflammation. Continue regular check-ups to monitor your health, and don't hesitate to seek a second opinion if needed.

My CRP is 100 and my Dr doesn’t know why. What other tests should be done to find the reason for this problem please

With a CRP level of 100, your doctor might recommend additional tests such as a Complete Blood Count (CBC), Erythrocyte Sedimentation Rate (ESR), liver and kidney function tests, and an autoimmune panel to determine the cause of the inflammation. Follow up with your doctor for a detailed evaluation and appropriate testing based on your symptoms.
