A "normal allergy level" is best understood by looking at serum IgE (immunoglobulin E) levels, which are measured by allergy tests. These tests help identify specific allergies.
Understanding IgE and Allergy Tests
Allergy tests, specifically serum IgE tests, measure the amount of IgE antibodies in your blood. IgE antibodies are produced by your immune system when it overreacts to allergens, which are typically harmless substances.
Normal Ranges for Serum IgE
According to the provided reference, the normal range for serum IgE can vary. However, the commonly accepted maximum limit is between 150 and 300 UI/ml. While the range may extend from 150 to 1,000 UI/ml, a value above 300 UI/ml typically indicates a potential allergy.
Measurement | Value Range |
---|---|
Common Maximum Limit | 150-300 UI/ml |
Extended Range | 150-1,000 UI/ml |
What Does This Mean for You?
- Below 150 UI/ml: Generally considered low and unlikely to indicate an allergy.
- 150-300 UI/ml: This is typically within the normal range.
- Above 300 UI/ml: May indicate an allergy, requiring further investigation to determine the specific allergen causing the reaction.
It is essential to consult with a healthcare professional for interpretation of specific allergy test results and to receive personalized medical advice.
