Allergy Diagnosis Tests - Drlogy


1. Skin Prick Test

  • A common allergy test involving small pricks on the skin to check for immediate allergic reactions.
  • Small amount of allergen extracts applied to the skin.
  • Measures allergic reactions, helps identify specific triggers.
Skin Prick Test  
Also Known As Allergy Prick Test
Purpose Identify immediate allergies
Sample Allergen extracts
Preparation No special preparation
Procedure Small pricks on the skin
Test Timing 15-30 minutes
Test Price (INR) 500 - 1500
Result Value Positive/negative reaction
Normal Value No reaction
Accuracy High
Interpretation Positive reaction indicates allergies.

The Skin Prick Test, also known as the Allergy Prick Test, accurately identifies immediate allergies through small pricks on the skin.


2. Patch Test

  • Detects delayed allergic reactions through application of allergens on the skin.
  • Helps identify contact allergens like metals, fragrances, and chemicals.
  • Evaluates skin sensitivity and guides avoidance strategies for allergen-triggered dermatitis.
Patch Test  
Also Known As Contact Allergy Test
Purpose Identify skin allergies
Sample Allergens applied to patches placed on skin
Preparation Patch placement on back or upper arm
Procedure Patches kept on for 48 hours, skin observed for reactions
Test Timing 48-72 hours
Test Price (INR) 1,500 - 5,000
Result Value Positive or negative indication of allergen sensitivity
Normal Value Absence of significant skin reactions
Accuracy Variable accuracy
Interpretation Positive reaction suggests contact allergy, while negative indicates absence of sensitivity

Patch Test, also known as the contact allergy test, identifies skin allergies caused by specific substances. It is accurate and dependable for diagnosing contact allergies.


3. Blood Test (RAST or ImmunoCAP)

  • Measures specific IgE antibodies in the blood to identify allergens causing allergic reactions.
  • Provides quantitative results indicating the level of sensitivity to different allergens.
  • Useful for individuals unable to undergo skin tests or when multiple allergens need to be tested simultaneously.
Blood Test (RAST or ImmunoCAP)  
Also Known As Specific IgE Test
Purpose Identify specific allergens triggering allergic reactions.
Sample Blood sample
Preparation Fasting required
Procedure Blood drawn, analyzed for specific IgE antibodies
Test Timing 1-2 days
Test Price (INR) 1,000 - 5,000.
Result Value Quantitative measurement of specific IgE levels
Normal Value Depends on specific allergen
Accuracy Reliable results
Interpretation High levels indicate sensitivity to specific allergens

A blood test (RAST or ImmunoCAP) measures specific IgE levels in the blood to identify allergens. It provides accurate results and helps determine allergic sensitivities.


4. Allergen-Specific IgE Test

  • Measures IgE antibodies in the blood to identify allergens causing allergic reactions. (98 characters)
  • Provides quantitative results, indicating the level of sensitivity to specific allergens. (92 characters)
  • Helps determine appropriate allergy treatment options and avoidance strategies.
Allergen-Specific IgE Test  
Also Known As IgE Blood Test
Purpose Identifying specific allergens
Sample Blood
Preparation Fasting required
Procedure Blood sample collection, analysis of IgE antibodies
Test Timing 1-2 days
Test Price (INR) 2,000 - 6,000
Result Value Quantitative measurement of IgE levels
Normal Value Varies with age, laboratory standards
Accuracy Specific allergen detection
Interpretation Higher IgE levels indicate sensitivity to specific allergens

The Allergen-Specific IgE Test, also known as the IgE Blood Test, identifies specific allergens causing reactions. It measures IgE levels accurately, providing valuable insights for allergy diagnosis and management.


5. Intradermal Test

  • Involves injecting small amounts of allergens under the skin to detect allergic reactions.
  • Useful for identifying allergies to medications, insect venom, or respiratory allergens.
  • Provides more sensitive results compared to other tests, helping with accurate diagnosis.
Intradermal Test  
Also Known As Intracutaneous Test
Purpose Detecting allergen sensitivity
Sample Allergen extracts
Preparation Cleaning the skin
Procedure Injecting allergens under skin
Test Timing A few days
Test Price (INR) 1500 - 3500
Result Value Positive or negative reaction
Normal Value No reaction
Accuracy Variable diagnostic accuracy
Interpretation Positive reaction indicates allergy

The Intradermal Test, also known as the Intracutaneous Test, detects allergen sensitivity through injected allergens. It helps guide treatment plans based on positive reactions, providing valuable insights into allergies.


Allergy Diagnosis Tests Overview

Test Price (INR) 500 - 1500 1,500 - 5,000 1,000 - 5,000.
Result Value Immediate skin reaction Skin reaction after patch removal IgE antibody levels
Normal Value No reaction No reaction Low levels of specific IgE antibodies
Accuracy High Variable accuracy Reliable results
Interpretation Positive reaction indicates allergy Positive reaction indicates allergy Elevated IgE levels may suggest an allergic response

*Test Price, range and timing may vary as per location, lab type, and procedure.

The Skin Prick Test, Patch Test, and Blood Test are vital in diagnosing allergies. They help identify immediate and delayed reactions, measure specific IgE antibodies, and guide effective treatment plans based on the results obtained.


Allergy Differential Diagnosis

Similar Diseases Differentiating Factors
Cold Absence of fever, duration of symptoms
Sinusitis Facial pain and pressure, sinus congestion
Asthma Recurrent episodes of wheezing, difficulty breathing
Eczema Rash with dry, itchy, and scaly skin
Food intolerance Non-immune response, gastrointestinal symptoms
Drug reactions Specific medication history, timing of symptoms

When differentiating allergies from similar diseases, factors like absence of fever, specific symptoms, and timing help distinguish them from conditions such as cold, sinusitis, asthma, eczema, food intolerance, and drug reactions.

Allergy Test FAQ

What is the best diagnostic test for allergies?

There is no single "best" diagnostic test for allergies, as the type of test used depends on the specific allergy being evaluated and the patient's individual circumstances. Some common tests include skin prick tests, blood tests, and oral food challenges.

Can a CBC detect allergies?

No, a CBC (complete blood count) cannot detect allergies directly. However, it may show certain changes that can suggest the presence of an allergic reaction, such as an increase in the number of eosinophils (a type of white blood cell) or changes in the levels of certain inflammatory markers.

How can I test for allergies at home?

Testing for allergies at home is not recommended as it may not be accurate and can lead to incorrect self-diagnosis and treatment. It is best to consult a healthcare professional who can perform reliable allergy tests and provide proper treatment.

Can allergies be cured?

Manage allergy symptoms with medication, lifestyle changes, and immunotherapy. Avoid allergens and work with a healthcare provider to find the right treatment plan.
