About this test
A cheddar cheese-specific IgE blood test checks for antibodies the immune system produces against proteins found in cheddar cheese. It is a screening tool for suspected dairy allergy and is not a diagnosis on its own. A healthcare provider may order it after a reaction to cheddar or other cheeses, or as part of a broader milk protein evaluation. Cheddar contains milk proteins such as casein and whey, so results are interpreted alongside other dairy markers and your symptom history.
What this test measures
- Cheddar cheese-specific IgE Antibodies produced against proteins in cheddar cheese, including casein and whey; used to assess sensitization.
Who this test may be right for
- People who develop hives, itching, or swelling after eating cheddar cheese
- Individuals with digestive upset, gas, or diarrhea after cheese
- Those with eczema or skin reactions that flare after dairy products
- People who suspect a milk protein reaction rather than lactose intolerance
- Anyone with a history of reaction to cheese or other dairy foods
Before your visit
- No fasting is required for this IgE allergy test
- The sample can be collected at any time
- Tell the provider about medications you take
- No special diet is needed beforehand
Understanding your results
The cheddar cheese-specific IgE result is reported as a numeric level or class. A value above the reporting threshold may indicate sensitization to proteins in cheddar, but sensitization does not always cause symptoms. A low or undetectable level makes a true cheese allergy less likely without completely ruling it out. Because cheddar contains both casein and whey, a provider may compare this result with casein or whey protein markers. Discuss results with a healthcare provider before changing your diet.

Questions people ask
What does the cheddar cheese-specific IgE test measure?
It measures antibodies against proteins in cheddar cheese, including casein and whey, which helps assess sensitization to cheddar.
Does cheddar cheese allergy mean I am lactose intolerant?
No. Lactose intolerance is a digestive issue with milk sugar, while cheddar cheese-specific IgE reflects allergic sensitization to cheese proteins.
Can cheddar allergy be related to other dairy foods?
Cheddar contains milk proteins also found in milk and other cheeses, so a healthcare provider may consider related dairy markers when interpreting cheddar cheese-specific IgE.
Do I need to fast?
No. This IgE allergy test requires no fasting and can be collected at any time.
