ALLERGY COMPONENT RESOLVED DIAGNOSTICS (CRD) PANEL in Pratap-vihar, Ghaziabad

Allergy Component Resolved Diagnostics (CRD) Panel: Price, Purpose, and Report Interpretation

Test Overview

Allergies can range from mild discomfort to life-threatening reactions, making an accurate diagnosis critical for effective treatment. The Allergy Component Resolved Diagnostics (CRD) Panel is an advanced diagnostic tool designed to detect and analyse allergic sensitivities at the molecular level. Unlike conventional allergy tests that detect reactions to broad allergen sources (such as pollen or peanuts), CRD testing pinpoints the specific allergen proteins that trigger the immune response. This high-precision approach helps differentiate between true allergies and cross-reactive sensitivities, cases where the immune system reacts to similar proteins found in unrelated substances. As a result, CRD testing provides deeper clinical insight into the nature and severity of allergic diseases, enabling more targeted treatment, prevention strategies, and safer management plans. If you are looking for an Allergy Component Resolved Diagnostics (CRD) Panel test near me, Apollo 24|7 provides NABL-certified testing facilities, home sample collection services, and secure digital report delivery across India. This guide explains the test’s price, purpose, preparation, procedure, and report interpretation, helping you understand why it plays a key role in modern allergy diagnostics.

What is the Allergy Component Resolved Diagnostics (CRD) Panel?

The CRD Panel is a blood-based test that identifies allergic sensitivity to specific molecular components (proteins) within an allergen source. It works by detecting IgE antibodies produced by the immune system in response to allergens. These antibodies are a hallmark of allergic conditions, including asthma, eczema, allergic rhinitis, and food allergies. Traditional allergy tests, such as skin prick or standard IgE panels, provide information about reactions to whole allergen extracts (for example, “peanut” or “pollen”). However, these extracts contain many proteins, not all of which cause true allergic reactions. The CRD test, on the other hand, analyses individual allergen molecules within these sources, identifying the exact proteins that trigger allergic responses. This level of precision helps determine whether the reaction is due to a primary sensitisation (a true allergy to a specific allergen) or cross-reactivity (a false-positive reaction due to similar protein structures shared among different allergens).

Components and Their Clinical Significance

Why is the Allergy Component Resolved Diagnostics (CRD) Panel Recommended?

Doctors recommend the CRD Panel for individuals who experience frequent or unexplained allergic symptoms or when conventional tests provide inconclusive results. The test is valuable in identifying specific allergy triggers and improving management strategies. Key reasons for recommending the test include:

• Accurate diagnosis: Determines the precise allergen protein causing the reaction.
• Differentiation of cross-reactivity: Distinguishes between true allergic sensitisation and cross-reactive patterns (e.g., birch pollen and apple allergy).
• Risk prediction: Helps assess the likelihood of severe allergic reactions, including anaphylaxis.
• Treatment planning: Enables doctors to design personalised management plans and recommend allergen-specific immunotherapy (AIT).
• Comprehensive allergy profiling: Ideal for patients with multiple or complex allergy triggers.

Allergy Component Resolved Diagnostics (CRD) Panel Price

The cost of the Allergy Component Resolved Diagnostics (CRD) Panel may vary depending on several factors:

• Location: Test prices can differ between urban and non-urban areas due to differences in laboratory infrastructure.
• Accreditation: NABL- or CAP-accredited laboratories, such as Apollo Diagnostics, may charge slightly more for enhanced accuracy and reliability.
• Technology Used: Advanced platforms such as ImmunoCAP ISAC, ALEX, or FABER are used for molecular allergy testing and contribute to the cost.
• Additional Parameters: Optional tests like total IgE, eosinophil count, or allergy-specific markers may be added as part of a package.

Purpose of the Allergy Component Resolved Diagnostics (CRD) Panel

The CRD Panel serves several diagnostic and clinical purposes, such as:

• Identifying True Allergen Sensitisation: It helps determine whether a person is genuinely allergic to a specific allergen or reacting to similar proteins found in another source.
• Personalising Treatment Plans: Based on the identified allergen components, your doctor can recommend targeted treatments such as immunotherapy, allergen avoidance, or antihistamine medication.
• Predicting Severity of Allergic Reactions: Certain allergen components are associated with more severe reactions. Detecting these helps doctors identify patients at risk of anaphylaxis or systemic allergy.
• Monitoring Therapy Progress: For individuals undergoing desensitisation therapy, CRD helps track immune response and tolerance development over time.
• Improving Quality of Life: By identifying triggers precisely, patients can avoid specific allergens, reduce symptoms, and live more comfortably.

Who Should Take the Allergy Component Resolved Diagnostics (CRD) Panel?

You should consider taking this test if you have one or more of the following symptoms or conditions:

• Recurrent sneezing, nasal congestion, watery eyes, or throat irritation
• Skin conditions such as hives, eczema, or rashes that worsen with exposure to certain triggers
• Food-related reactions, such as swelling, stomach pain, nausea, or breathing difficulty
• Insect venom allergy (bee or wasp stings causing swelling or dizziness)
• Asthma that worsens seasonally or after exposure to specific allergens
• Unexplained allergic symptoms with unclear causes
• Multiple sensitivities detected in standard allergy panels that require further investigation

Doctors may also recommend this test for patients undergoing immunotherapy, those with complex allergy profiles, or individuals who require risk assessment for severe allergic reactions.

Understanding the Allergy Component Resolved Diagnostics (CRD) Panel Report

The test results are typically presented as quantitative measurements of IgE antibodies (in kU/L) against various allergen components, along with a total IgE level. Each allergen component result is categorised as negative, low, moderate, or high, depending on antibody concentration.

Typical Reference Ranges

Interpretation Notes:

• A negative result suggests no significant allergic sensitisation.
• Low to moderate levels may indicate mild or localised reactions.
• High levels indicate significant sensitisation and a greater likelihood of clinical allergy symptoms.
• The pattern of results helps identify cross-reactive allergens and guides therapy choices.

Important: Always consult your doctor for report interpretation. The significance of each allergen component depends on your clinical history and symptoms.

Importance of Early Detection

Early identification of allergen sensitivities offers several benefits:

• Prevention of severe allergic episodes, including anaphylaxis.
• Improved management through avoidance of confirmed allergens.
• Targeted therapy, such as allergen-specific immunotherapy, for long-term relief.
• Reduced medication dependence through personalised treatment.
• Better understanding of cross-reactive allergies preventing unnecessary dietary or lifestyle restrictions.

By detecting allergy risks early, individuals can make informed lifestyle choices and improve their overall well-being.
