Navigating CRD Testing

Are you tired of frequent doctor's appointments, costly treatments, and ineffective medication for your allergies? Have traditional allergy tests failed to accurately identify the root cause of your symptoms? If so, it may be time to consider a relatively new approach called component-resolved diagnosis (CRD).

However, as more research is being conducted on personalized healthcare, a new diagnostic tool has emerged – Component-Resolved Diagnosis (CRD). In this post, we will explore the CRD test.

Understanding CRD Testing

Component-resolved diagnosis (CRD) testing is a diagnostic tool used to determine the underlying cause of an allergic reaction. Unlike traditional allergy testing, CRD testing can identify the specific component of an allergen that triggers an allergic reaction.

CRD Testing stands for Component-Resolved Diagnosis Testing. It involves using purified native or recombinant allergens to detect IgE sensitivity and is particularly used in diagnosing Type I allergies.

The test is designed to identify specific IgE antibodies against molecular components like recombinant allergenic proteins or pure components derived from natural products. CRD is utilized in skin prick testing (SPT) to pinpoint allergens causing allergic reactions, enhancing the precision of allergy diagnosis.

This test is particularly useful for those who suffer from severe allergies or have not found relief with traditional allergy testing. Explore how CRD testing works, its benefits, and what to expect during the testing process.

How does CRD Testing Work?

CRD testing works by separating the different components of an allergen and testing them individually for an allergic response. During the test, a small amount of blood is drawn from the patient and sent to a lab for analysis. The lab then tests the blood sample for specific allergy antibodies known as immunoglobulins (IgE). The test results will show which components of the allergen the patient is allergic to.

Importance of CRD Testing

The CRD test detects specific allergen components that can lead to accurate diagnosis, effective treatment, and better patient outcomes. Find the importance of CRD testing and how it can benefit allergy sufferers.

  1. Improved Accuracy: Conventional allergy testing involves identifying an allergen by measuring the immunoglobulin E (IgE) antibody response in blood or skin. However, the IgE response does not identify which component of an allergen caused the reaction.

    In contrast, CRD testing can identify the specific components of an allergen that trigger the reaction. This specificity leads to more accurate diagnosis and targeted treatment, which reduces the severity and frequency of symptoms.

  2. Efficient and Effective Treatment: CRD blood tests are efficient and can identify a broader range of allergens than skin prick testing. Once the allergens are identified, allergy shots or immunotherapy are precise, targeting the specific allergens that cause the reaction.

    This targeted treatment is effective and can significantly reduce the severity of symptoms or even eradicate them altogether. The precision of CRD testing not only improves treatment outcomes but also saves patients from undergoing unnecessary and ineffective treatments.

  3. Reduction in Health Care Costs: The accuracy and effectiveness of CRD testing minimize the need for additional testing and treatments, reducing health care costs significantly. Since the diagnostic accuracy is higher, patients experience fewer reactions, reducing the number of hospital visits, and the length of hospital stays.

    CRD testing results in fewer medications, visits to health care facilities, and missed workdays, improving the patient's quality of life.

  4. Useful in Complex Cases: CRD testing is particularly valuable in patients with complex allergic conditions. Traditional diagnostic techniques like skin prick testing may fail to diagnose patients with multiple allergies or different allergy sources.

    However, CRD testing can differentiate between similar allergens, which is helpful in such complex cases. This testing can also accurately diagnose conditions like oral allergy syndrome (OAS), which is challenging to diagnose with traditional diagnostic methods.

  5. Risk-Free Diagnostic Technique: Traditional allergy testing methods like skin prick testing that involves testing different allergens on the skin or administering a substance under the skin, may cause discomfort or even a severe allergic reaction. Whereas, CRD testing is a risk-free method involving a simple blood draw.

    This technique is particularly beneficial for children, the elderly, and people with chronic medical conditions, making allergy diagnosis easier and more accessible

CRD Test Price in India

The CRD test, or Component-Resolved Diagnostics, is utilized to identify specific IgE sensitivity to individual allergenic molecules. Here's information on the price:

  • The CRD test price in Delhi and Gurgaon is ₹25,500.
  • In Mumbai, the price for the Allergy Component Testing (CRD) is ₹20,000.
  • To book the CRD test package online, Pathkind Labs provides Allergy Component Testing at NABL-accredited labs.

It's essential to note that prices may vary, and individuals should consult their healthcare provider for accurate and up-to-date information.


Having a clear understanding of your body's immune response is crucial in maintaining good health.
