Cinnamon (F220) IgE Blood Biomarker Testing
It measures IgE sensitization to cinnamon to help assess allergy risk, with convenient ordering and clear results through Vitals Vault’s Quest network.
With Vitals Vault, you have access to a comprehensive range of biomarker tests.
A Cinnamon (F220) IgE test checks whether your immune system has made allergy-type antibodies (IgE) that recognize cinnamon. It is most useful when you have symptoms that seem to happen after exposure to cinnamon as a spice, flavoring, or ingredient.
Because cinnamon shows up in foods, drinks, candies, toothpastes, and some supplements, reactions can be confusing to track. A blood test can help you and your clinician decide whether cinnamon is a likely trigger or whether you should look for a different cause.
This test does not diagnose an allergy by itself. Your symptoms, timing, and overall risk matter, and sometimes follow-up testing or a supervised food challenge is needed to confirm what the number means for you.
Do I need a Cinnamon F220 IgE test?
You may want a Cinnamon (F220) IgE test if you notice repeat symptoms within minutes to a few hours after eating foods that contain cinnamon or after inhaling cinnamon dust while cooking or baking. Symptoms that fit an IgE-type reaction can include hives, itching, lip or mouth tingling, throat tightness, wheezing, coughing, or vomiting. Severe reactions are uncommon but possible, so a clear plan matters if you have had rapid-onset symptoms.
This test can also be helpful if you have unexplained flares of eczema (atopic dermatitis) or chronic hives and you suspect a spice trigger, especially when your food diary points toward cinnamon-containing products. If you have oral itching or swelling with certain fruits and spices, your clinician may consider pollen-food allergy patterns and use targeted IgE tests to narrow the list.
You may not need this test if your symptoms are delayed by many hours or days, mainly digestive (bloating, cramps) without other allergy features, or occur inconsistently. Those patterns are more often related to intolerance, reflux, infection, or non-IgE immune pathways.
Testing is most useful when it supports clinician-directed decision-making, such as choosing avoidance steps, deciding whether you need an epinephrine plan, or selecting follow-up tests to confirm the trigger.
This is a CLIA-performed blood test for allergen-specific IgE; results support clinical assessment and are not a standalone diagnosis of food allergy.

Get this test with Vitals Vault
Vitals Vault lets you order a Cinnamon (F220) IgE blood test without the usual back-and-forth. You choose the test, complete checkout, and then visit a nearby Quest draw site for the blood sample.
When your result is ready, you can use PocketMD to put the number into context with your symptoms, other allergies, and your current medications. That is especially helpful with IgE testing because a “positive” result can mean sensitization without clear clinical reactions, and a “negative” result does not always rule out a trigger.
If you are mapping broader patterns, you can add companion allergy tests (for related foods or environmental triggers) and then retest later if your exposure changes or your clinician recommends monitoring. Your goal is a practical plan: what to avoid, what to watch for, and what follow-up is worth doing.
- Order online and draw at a Quest location
- PocketMD helps you interpret results in plain language
- Easy reordering if you and your clinician decide to retest
Key benefits of Cinnamon F220 IgE testing
- Helps identify whether cinnamon is a plausible trigger for rapid-onset allergy symptoms.
- Distinguishes IgE sensitization from other causes of food-related symptoms that do not involve IgE.
- Supports safer decision-making about avoidance, label reading, and cross-contact risk in foods.
- Guides whether follow-up testing (broader spice/food IgE panels or skin testing) is likely to add value.
- Helps you and your clinician decide when a supervised oral challenge is appropriate versus unnecessary.
- Provides a baseline number that can be trended if your exposure or symptoms change over time.
- Pairs well with PocketMD guidance so you can connect the lab result to real-world symptoms and next steps.
What is Cinnamon F220 IgE?
Cinnamon (F220) IgE is a blood measurement of allergen-specific immunoglobulin E (IgE) antibodies that recognize proteins found in cinnamon. IgE is the antibody class involved in immediate-type allergic reactions. When you are sensitized, your immune system has “learned” to react to that allergen, and exposure can trigger histamine release and other inflammatory signals.
The test reports a quantitative value (often in kU/L) and may also provide a class or category based on that value. Higher values generally suggest a higher likelihood of clinical reactivity, but the relationship is not perfect. Some people have measurable IgE without symptoms, while others have symptoms with low or even undetectable IgE depending on the allergen, the assay, and the type of reaction.
Cinnamon reactions can be complicated because cinnamon is used in small amounts, can be inhaled as a powder, and can overlap with other spice sensitivities. In addition, some mouth or throat symptoms may reflect cross-reactivity patterns rather than a classic food allergy.
Sensitization vs. allergy
A positive cinnamon-specific IgE result means your immune system recognizes cinnamon, which is called sensitization. Allergy is when sensitization matches your real-life symptoms and timing. Your clinician uses your history to decide whether the lab result is clinically meaningful.
Why symptoms and timing matter
IgE-mediated reactions usually happen quickly after exposure, often within minutes to a couple of hours. If your symptoms are delayed, inconsistent, or mainly gastrointestinal without other allergy features, a cinnamon IgE result may not explain what you are experiencing.
What do my Cinnamon F220 IgE results mean?
Low Cinnamon (F220) IgE
A low or undetectable result makes an IgE-mediated cinnamon allergy less likely, especially if your symptoms are immediate-type and reproducible. However, it does not fully rule out cinnamon as a trigger because reactions can be non-IgE mediated, dose-dependent, or related to another ingredient in the same product. If your history is strongly suggestive, your clinician may consider skin testing, testing for other spices, or a supervised challenge rather than relying on one blood test.
In-range / negative Cinnamon (F220) IgE
Many labs report a reference range where results below a cutoff are considered negative. If you are in that range and you do not have convincing immediate symptoms, cinnamon is less likely to be the cause and it may be more useful to look at other triggers such as different spices, additives, or environmental allergies. If you do have symptoms that fit an allergic pattern, the next step is usually a careful review of exposure timing and consideration of targeted follow-up testing.
High Cinnamon (F220) IgE
A higher result suggests stronger sensitization and increases the chance that cinnamon exposure could cause symptoms, particularly if you have had rapid-onset hives, mouth/throat symptoms, wheezing, or vomiting after cinnamon-containing foods. The number alone still does not predict reaction severity, so it should not be used to “grade” how dangerous cinnamon is for you. Your clinician may recommend a clear avoidance plan, evaluation for related allergies, and an emergency plan if you have had systemic reactions.
Factors that influence Cinnamon (F220) IgE
Your total IgE level, eczema severity, and other allergic diseases can raise the likelihood of low-level positives that do not match symptoms. Recent exposures and seasonal pollen patterns can sometimes change IgE results over time, especially when cross-reactivity is involved. Medications like antihistamines do not typically suppress blood IgE results, but they can mask symptoms and make your history harder to interpret. Lab methods and reporting (numeric value vs. class) vary, so comparing results is most reliable when you use the same lab method over time.

Frequently Asked Questions
Do I need to fast for a Cinnamon (F220) IgE blood test?
Fasting is not usually required for allergen-specific IgE testing. If you are having other labs drawn at the same visit, follow the fasting instructions for the full set of tests you ordered.
What does a positive Cinnamon IgE test mean?
A positive result means you are sensitized, meaning your immune system has made IgE antibodies that recognize cinnamon. Whether that equals a true allergy depends on your symptoms and timing after exposure. Your clinician may use your history and sometimes additional testing to confirm clinical allergy.
Can I have a cinnamon allergy with a negative IgE test?
Yes. A negative test makes IgE-mediated allergy less likely, but it does not rule out non-IgE reactions, irritation, or reactions to other ingredients commonly found with cinnamon. If your symptoms are consistent and concerning, discuss next steps such as broader testing or a supervised challenge with your clinician.
Is Cinnamon (F220) IgE the same as a food sensitivity test (IgG)?
No. Cinnamon IgE testing looks for immediate-type allergy antibodies (IgE). IgG “food sensitivity” tests measure a different antibody class and do not diagnose food allergy; IgG can reflect exposure rather than a harmful reaction.
How long after a reaction should I wait to test IgE?
You can usually test at any time because specific IgE tends to be relatively stable. If you recently had a severe reaction, your clinician may still recommend testing promptly as part of the evaluation, while also considering that results should be interpreted alongside your clinical history.
Should I retest Cinnamon IgE, and if so, when?
Retesting can be useful if your exposure changes, your symptoms change, or you and your clinician are tracking whether sensitization is increasing or decreasing over time. Many people retest no sooner than several months, since IgE levels typically do not shift meaningfully week to week.
Can cinnamon cause contact reactions instead of a food allergy?
Yes. Some people react to cinnamon in the mouth or on the skin through irritation or contact allergy mechanisms, which may not be captured by an IgE blood test. If your symptoms are mainly localized (for example, mouth soreness from cinnamon gum or skin rash from topical products), ask your clinician whether patch testing or a dermatology evaluation is more appropriate.
