A CRP test measures C-reactive protein in the blood, which rises when there is inflammation or infection in the body.

When should I take a CRP test?

If you have signs of infection, chronic pain, unexplained fever, or if your doctor wants to monitor a condition, a CRP test is recommended.

What causes high CRP levels?

High CRP levels may result from bacterial infections, autoimmune conditions, inflammatory diseases, or cardiovascular problems.

Do I need to fast for a CRP test?

Fasting is not typically required for a CRP test unless other tests are done alongside it.

Where can I get a CRP test done in India?

CRP tests are available through labs like Thyrocare, which you can access easily via platforms like SecondMedic for home collection.

CRP Test Meaning And When To Do It

Book your checkup

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:

You have fever or chills that won’t go away
You’re showing signs of infection like cough, swelling, or pain
Your doctor is monitoring an autoimmune disease
You’re recovering from surgery or injury
Your doctor is checking inflammation due to chronic disease
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).

Genetic Predisposition Testing India: Understanding Your DNA to Prevent Future Disease

Genetics plays a significant role in determining an individual’s risk for various diseases. In India, where chronic illnesses like diabetes, heart disease, cancer, and neurological disorders are increasing rapidly, genetic predisposition testing has emerged as a powerful preventive tool. It helps individuals understand inherited risk factors long before symptoms appear, allowing timely intervention.

SecondMedic offers guided genetic screening to help patients uncover DNA-based risks and take proactive control of their long-term health.

What Is Genetic Predisposition Testing?

Genetic predisposition testing analyzes a person’s DNA to identify mutations, variations, or inherited markers associated with increased disease risk. It does not diagnose a disease but reveals how likely an individual is to develop certain conditions.

What the test identifies:

Gene mutations
Family-linked disease patterns
Hereditary cancer markers
Metabolic and cardiovascular risks
Neurological conditions
Autoimmune predispositions

These insights help individuals and doctors make informed preventive health decisions.

Why Genetic Testing Is Growing in India

1. High prevalence of lifestyle and hereditary diseases

India is the diabetes capital of the world, and many metabolic disorders have genetic roots.

2. Increasing cancer burden

BRCA and other hereditary cancer syndromes are being detected more often.

3. Awareness about preventive healthcare

People want to act early rather than wait for disease onset.

4. Growth of digital healthcare

Easy access through telemedicine platforms like SecondMedic.

5. Rising chronic cases at younger ages

Genetic predispositions often accelerate early onset of disease.

What Diseases Can Genetic Testing Predict?

1. Cancer Risk

Includes hereditary cancers such as:

Breast
Ovarian
Colorectal
Prostate
Pancreatic

BRCA1, BRCA2, and Lynch syndrome genes are key markers.

2. Heart Disease & Hypertension

Genes that influence:

Cholesterol levels
Plaque formation
Blood pressure regulation

3. Diabetes

Genes that affect insulin sensitivity and metabolic function.

4. Obesity

Markers linked to appetite regulation and fat storage.

5. Neurological Disorders

Including Alzheimer’s, Parkinson’s, and epilepsy predispositions.

6. Autoimmune Diseases

Genes related to lupus, rheumatoid arthritis, and thyroid disorders.

7. Drug Response (Pharmacogenomics)

DNA determines how the body reacts to certain medications.

How Genetic Predisposition Testing Works

Step 1: Sample Collection

Usually saliva, blood, or buccal swab.

Step 2: DNA Sequencing

Advanced technology identifies variations in your genome.

Step 3: Risk Analysis

Gene mutations are mapped to known disease risks.

Step 4: Expert Interpretation

SecondMedic’s genetic counsellors and doctors review results.

Step 5: Preventive Plan

Includes recommended lifestyle changes, screenings, and monitoring.

Benefits of Genetic Predisposition Testing

1. Detect Risk Before Symptoms

Allows decades of preventive action.

2. Personalized Health Planning

Diet, exercise, and medical screening tailored to DNA.

3. Early Cancer Detection

Essential for women with hereditary breast/ovarian cancer risk.

4. Family Health Insights

Identifies conditions that may affect children and siblings.

5. Improved Treatment Outcomes

Knowing your risk helps doctors monitor you more closely.

6. Better Drug Selection

Pharmacogenomics ensures medications match your genetic profile.

Who Should Consider Genetic Testing?

People with family history of cancer
Individuals whose relatives had early heart attacks
Families with diabetes across generations
Women with breast or ovarian cancer history
Couples planning pregnancy
People with unexplained chronic conditions
Individuals wanting personalized preventive healthcare

Limitations of Genetic Testing

1. Not a diagnosis

It shows probability, not certainty.

2. Environmental and lifestyle factors still matter

Genes interact with habits and environment.

3. Requires professional interpretation

Raw results without counselling can be confusing.

SecondMedic ensures accurate guidance through experienced specialists.

How SecondMedic Supports Genetic Testing

1. End-to-End Genetic Screening

From sample collection to detailed analysis.

2. Expert Review

Genetic counselors and doctors explain every risk factor.

3. Personalized Preventive Plan

Nutrition, exercise, and screening based on DNA.

4. Confidential Reporting

All data is securely stored.

5. Integrated Preventive Tracking

Follow-up tests and monitoring for high-risk individuals.

Future of Genetic Testing in India

AI-based genome interpretation
Affordable whole-genome sequencing
Predictive analytics for early cancer
Family-wide health risk mapping
Integration with digital health IDs under ABDM

SecondMedic aims to make genetic screening widely accessible and scientifically guided.
