What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining whether you have IgE sensitization to cilantro/coriander and what that means for your diet. These notes include personalized recommendations like which foods to avoid, how to read ingredient labels, and whether you should consider testing for related allergens. You'll also get the standard lab report and can track your IgE levels over time using our trends feature, especially helpful if you're monitoring sensitivity changes or implementing dietary changes.

When will I get my results?

Most allergy blood test results are available within 3-5 business days after your sample reaches the laboratory. You'll receive an email notification when your results are ready to view in your secure online account. Complex cases or high testing volumes may occasionally extend this timeframe slightly.

Who should consider getting this test?

This test is ideal for people who experience symptoms like stomach cramps, nausea, skin rashes, or breathing difficulties after eating Mexican, Indian, Thai, or other cuisines that commonly use cilantro. It's also useful for anyone with unexplained allergic reactions who wants to identify specific food triggers, or those with known allergies to other herbs and spices who want to check for cross-reactivity. People with widespread skin conditions or those taking antihistamines may prefer blood testing over skin prick tests.

What symptoms indicate I may need this test?

Common symptoms of cilantro allergy include digestive issues like nausea, stomach pain, or diarrhea after eating foods containing the herb. You might also experience skin reactions such as hives, itching, or eczema flare-ups, or respiratory symptoms like sneezing, runny nose, or difficulty breathing. Some people notice tingling or swelling in the mouth, lips, or throat shortly after consuming cilantro or coriander.

How can I manage a cilantro allergy naturally?

The most effective way to manage a cilantro allergy is strict avoidance of both fresh cilantro leaves and coriander seeds, as they come from the same plant. Carefully read ingredient labels and inform restaurant staff about your allergy when dining out, especially at Mexican, Asian, or Middle Eastern restaurants. Consider carrying alternative herbs like parsley or basil for recipes, and always have antihistamines available in case of accidental exposure.

What does a positive IgE result mean?

A positive IgE result means your immune system has produced specific antibodies against cilantro/coriander proteins, indicating IgE sensitization. However, not everyone with positive IgE develops symptoms when eating cilantro, so your doctor will consider your clinical history alongside test results. Higher IgE levels may suggest a greater likelihood of allergic reactions, but the test alone cannot predict symptom severity.

Can cilantro allergy develop suddenly in adults?

Yes, food allergies including cilantro allergy can develop at any age, even if you've eaten the herb without problems for years. Adult-onset food allergies are increasingly common and may be triggered by changes in gut health, immune system shifts, or repeated exposure. If you suddenly develop symptoms after eating cilantro, allergy testing can help confirm whether an IgE-mediated allergy has developed.

How often should I retest my cilantro allergy?

If you have a confirmed cilantro allergy, retesting every 1-2 years can help monitor whether your sensitivity is increasing, decreasing, or remaining stable. Some food allergies can resolve over time, especially with strict avoidance, while others persist lifelong. If you've been avoiding cilantro and want to know if you've outgrown the allergy, discuss supervised retesting with your allergist before attempting to reintroduce the food.
