If you’ve recently had blood work or your doctor suspects an infection or inflammation, they may have recommended a CRP test. But what is it? Why is it important? And when exactly should you get it done?

Let’s simplify the medical jargon and walk you through the CRP test meaning and when to do it, especially in the Indian healthcare context.

What Is a CRP Test?

CRP stands for C-reactive protein. It is a substance produced by your liver in response to inflammation in the body.

The CRP test is a blood test that measures the amount of C-reactive protein in your blood. High levels of CRP usually mean there’s inflammation in your body, which could be due to an infection, injury, or a chronic disease like arthritis.

High CRP = Inflammation Alert

This test doesn’t tell you what’s causing the inflammation—it simply tells you that something is wrong, and further testing might be needed.

What Does the CRP Test Detect?

While CRP is a general marker, it is helpful in detecting:

  • Bacterial or viral infections
     

  • Autoimmune disorders like rheumatoid arthritis or lupus
     

  • Inflammatory bowel diseases
     

  • COVID-19 severity
     

  • Heart disease risk (especially with high-sensitivity CRP or hs-CRP)
     

When Should You Do a CRP Test?

You should get a CRP test done when:

  1. You have fever or chills that won’t go away
     

  2. You’re showing signs of infection like cough, swelling, or pain
     

  3. Your doctor is monitoring an autoimmune disease
     

  4. You’re recovering from surgery or injury
     

  5. Your doctor is checking inflammation due to chronic disease
     

  6. You are showing COVID-like symptoms (to assess severity)
     

Normal CRP Levels:

CRP Level

Interpretation

Below 1 mg/L

Low risk of inflammation

1–3 mg/L

Moderate risk

Above 3 mg/L

High inflammation or infection present

Above 10 mg/L

May indicate serious infection or disease

Note: For heart disease risk, a high-sensitivity CRP (hs-CRP) test is used.

Is Fasting Required for the CRP Test?

No, fasting is not required. You can take the CRP test at any time of day, unless it is being done with other tests that require fasting (like blood sugar or cholesterol).

Simple Habits to Avoid High Cholesterol

Simple Habits to Avoid High Cholesterol

High cholesterol is one of the leading causes of heart disease and stroke worldwide. In India, rising cholesterol levels are becoming more common due to sedentary lifestyles, unhealthy food habits, and stress. But the good news is—you can prevent high cholesterol naturally with a few simple habits.

In this blog, we’ll explore easy, everyday steps you can take to keep your cholesterol levels in check and protect your heart.

 

What Is Cholesterol?

Cholesterol is a fatty substance found in your blood. While your body needs some cholesterol to build cells and hormones, too much of the wrong type—called LDL (low-density lipoprotein)—can be harmful. It can build up in your arteries and increase your risk of heart disease and stroke.

There’s also HDL (high-density lipoprotein), which is the “good” cholesterol that helps remove LDL from your body.

 

Why High Cholesterol Is Dangerous

  • Clogs arteries and restricts blood flow
     

  • Increases risk of heart attacks and strokes
     

  • Can lead to high blood pressure
     

  • May affect kidney and liver function
     

The scariest part? High cholesterol usually has no symptoms. That’s why it’s called a silent killer and must be managed before problems begin.

 

7 Simple Habits to Avoid High Cholesterol

 

1. Eat Fiber-Rich Foods Daily

Soluble fiber binds with cholesterol in the gut and removes it from your body.

Best foods for fiber:

  • Oats and barley
     

  • Apples, pears, and oranges
     

  • Beans and lentils
     

  • Flaxseeds and chia seeds
     

Tip: Start your morning with a bowl of oatmeal and add a fruit—it’s a heart-healthy breakfast!

 

2. Stay Active Every Day

Physical activity boosts HDL (good cholesterol) and burns fat that raises LDL.

What to do:

  • Walk briskly for 30 minutes a day
     

  • Try yoga, cycling, or dancing
     

  • Use stairs instead of the lift
     

  • Take short walks after meals
     

Even small movements throughout the day matter.

 

3. Cut Down on Saturated & Trans Fats

These fats raise your LDL cholesterol quickly.

Avoid:

  • Fried food, chips, and baked snacks
     

  • Ghee-heavy sweets
     

  • Processed foods with “hydrogenated oils”
     

Choose instead:

  • Olive oil or mustard oil
     

  • Grilled or baked foods
     

  • Fresh fruits and nuts as snacks
     

 

4. Manage Your Stress

Stress affects your hormones and may raise your cholesterol over time.

Try this:

  • Practice deep breathing or meditation
     

  • Do relaxing hobbies like reading or gardening
     

  • Take tech breaks and sleep 7–8 hours daily
     

  • Talk to someone if you’re feeling overwhelmed
     

A calm mind supports a healthy heart.

 

5. Stay Hydrated and Cut Sugary Drinks

Water helps regulate body functions and weight, which both impact cholesterol.

Do this:

  • Drink 8–10 glasses of water daily
     

  • Avoid soft drinks and energy drinks
     

  • Switch to herbal teas or infused water
     

Too much sugar can raise triglyceride levels, a type of fat in your blood.

 

6. Quit Smoking and Limit Alcohol

Smoking lowers good cholesterol and damages arteries. Alcohol, in excess, can also spike cholesterol and blood pressure.

Tip:
Even reducing smoking or drinking frequency helps your heart function better.

 

7. Get Regular Cholesterol Tests

Don’t wait for symptoms. Get your lipid profile checked every year, especially if you have:

  • A family history of heart disease
     

  • Diabetes or high blood pressure
     

  • Obesity or unhealthy lifestyle habits
     

Suggested Test:
Lipid Profile Test by Thyrocare via SecondMedic.com – includes LDL, HDL, total cholesterol, and triglycerides with home sample collection.

Ideal Range

  • Cook at home more often than eating out
     

  • Maintain a healthy weight
