Allergy Skin Test - Histamine
We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.
Allergy skin tests are used to determine if a person is allergic to specific substances, such as foods, medications, or environmental allergens like pollen or pet dander. The histamine skin test is a type of skin test that helps evaluate the body's overall ability to react to allergens.
The Role of Histamine in Allergic Reactions
Histamine is a chemical naturally produced by the body. It plays an important role in the immune system's response to allergens. When an allergic reaction occurs, the body releases histamine, which causes common allergy symptoms like sneezing, itching, hives, and nasal congestion.
In the histamine skin test, a small amount of histamine is injected under the skin. The resulting reaction, if any, is observed and measured to assess the body's overall sensitivity to histamine.
Table 1: Components Involved in the Histamine Skin Test| Component | Description |
|---|---|
| Histamine Solution | A controlled amount of histamine is introduced to the skin. |
| Skin Reaction | The resulting skin reaction, such as redness, swelling, or a wheal (raised area), is observed and measured. |
The histamine skin test helps determine if a person's immune system is capable of mounting an allergic response. It can also help evaluate the effectiveness of antihistamine medications, as a positive reaction indicates that the body is releasing histamine.
Role of Allergy Skin Test - Histamine
The Allergy Skin Test - Histamine is an important diagnostic tool used to evaluate an individual's sensitivity to histamine, a chemical released by the body during an allergic reaction. This test helps identify histamine-related allergies or conditions, such as urticaria (hives) or anaphylaxis (severe allergic reaction). The test results can assist healthcare professionals in developing appropriate treatment plans and managing allergic conditions effectively.
Indications for Allergy Skin Test - Histamine
The Allergy Skin Test - Histamine may be recommended in the following situations:
- Evaluation of suspected histamine intolerance or histamine-related allergies
- Diagnosis of chronic idiopathic urticaria (hives of unknown cause)
- Assessment of the risk of anaphylaxis or severe allergic reactions
- Monitoring of treatment response in individuals with histamine-related conditions
- Screening for potential histamine sensitivity before undergoing certain medical procedures or treatments
Preparation for the Allergy Skin Test - Histamine Procedure
Before undergoing the Allergy Skin Test - Histamine, it is important to follow these recommendations:
- Inform your healthcare provider about any medications, supplements, or herbal products you are taking, as some may interfere with the test results.
- Avoid taking antihistamines for a specified period before the test, as they can suppress the skin's reaction and affect the accuracy of the results.
- Ensure that your skin is free from rashes, eczema, or other skin conditions that may interfere with the test interpretation.
- Avoid excessive physical activity or exposure to extreme temperatures on the day of the test, as these factors can influence the skin's reactivity.
The Allergy Skin Test - Histamine Procedure
The Allergy Skin Test - Histamine is typically performed on the forearm or back. The procedure involves the following steps:
- Small amounts of histamine and other test substances are applied to the skin, either through a scratch or injection.
- After a specified period, usually 15-20 minutes, the healthcare provider will examine the skin for any reactions, such as redness, swelling, or raised bumps.
- The size and severity of the reactions are measured and recorded for interpretation.

If you experience any pain or exacerbation of a condition, it is essential to seek medical attention for proper diagnostic testing. Only a qualified healthcare professional can make an accurate diagnosis and determine the appropriate treatment. To ensure the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use different methods and units of measurement for similar tests.
