This Lemon Allergy Test uses a blood sample to determine whether or not you are allergic to lemons. Those with lemon allergies are prone to rashes, watery eyes, wheezing, and in extreme cases, anaphylaxis. Though lemon allergies are rare, in many cases, those with lemon allergies can be allergic to other citrus fruits as well. For this reason, we suggest covering multiple bases at once (and saving money) with a multi-panel citrus fruit allergy test. To identify a specific lemon allergy, order the Priority Lab Testing Lemon Allergy Test today.

For our lemon allergy test, simply place your order online and stop by one of our 4000+ nationwide testing facilities at your convenience (no appointments). A member of the center’s staff will collect a small blood sample via the skin prick method, at which point your part of the process is done.

The sample collection itself takes only a few minutes, and most patients are in and out and about their day in under half an hour. From there, your sample will be processed in a CLIA-certified laboratory, and in as little as 24-72 hours, you’ll have full results regarding your lemon intolerance.

Common Lemon Allergy Symptoms

According to the CDC, food allergies are a growing food safety and public health concern in the United States, especially in children. Any food, including fruits such as lemon, can trigger allergic reactions.1 While lemon allergies are relatively uncommon, allergic reactions to lemon have been known to occur.

Hypersensitive people who ingest or come into contact with lemons or lemon-based products may experience mild to moderate allergic symptoms. However, eating food or drinks made with raw lemons is the most common cause of allergy symptoms. A lemon allergy occurs when the immune system mistakes a protein called profilin in the fruit for a harmful invader.

The immune system subsequently releases antibodies and histamines into the blood to combat the profilins, triggering the symptoms of an allergic reaction. Symptoms of a lemon allergy can occur within minutes after contact with the fruit or can take up to a few hours to manifest.

Common lemon allergy symptoms include:

  • Extreme itching
  • Burning skin
  • Rash
  • Watery eyes
  • Redness
  • Swelling
  • Blisters
  • Cramps or vomiting

How to Interpret Your Results

Our Immunoglobulin E (IgE) allergy test uses a blood sample to determine if you are allergic to Lemons, a popular member of the citrus family. IgE are antibodies produced by the immune system when it detects an allergen. If you are allergic to lemons, you are also highly likely to be allergic to other citrus fruits.

At first glance, the results of a lemon allergy test can seem confusing for someone with no medical training. But it’s vital that you take your time to interpret your results accurately in order to understand your status. When reviewing your test results, you will most likely find the name of the test, a ‘result,’ ‘reference range,’ and ‘flag’ columns.

The ‘reference range’ refers to the threshold for an allergic reaction. The ‘result’ denotes the numerical value depicting your sensitivity to the allergen. The ‘flag’ column shows the outcome of your lemon allergy test, reported as either normal/unreactive or abnormal/reactive. The latter indicates an allergic reaction to lemons.

What Are the Possible Complications of Lemon Allergy?

Usually, allergic reactions to lemon range from mild to moderate, depending on your sensitivity levels. But if you are hypersensitive, your allergic reaction to lemons can be severe. A severe allergic reaction to lemons can lead to a response known as anaphylaxis, causing the immune system to release a flood of chemicals that can cause you to go into shock.

Anaphylactic shock may cause the airways to tighten, making it difficult for you to breathe, along with other complications. Anaphylaxis is a medical emergency and can be life-threatening.

Here are some of the most common signs of anaphylaxis to look out for:

  • A sudden drop in blood pressure
  • Extreme dizziness or loss of consciousness due to low blood pressure
  • Nausea, vomiting, and diarrhea
  • Asthma
  • Swelling of the mouth and throat
  • Flushed skin
  • Hives

Symptoms of anaphylaxis, a systemic allergic reaction, may vary from one person to another. It may take minutes or a few hours for anaphylaxis symptoms to manifest. Go to the emergency room right away if you are experiencing any combination of the above symptoms.


  • An allergen is any typically harmless substance that elicits an immediate allergic reaction in a susceptible person. In people with allergic sensitivities, the immune system recognizes allergens as foreign or dangerous substances and attacks them, resulting in the symptoms of an allergic reaction.

  • Ingesting or coming into contact with lemon may result in an allergic reaction in people with lemon intolerance. If you have lemon intolerance, you might experience itching, redness, swelling, and dryness of the skin after eating or touching a lemon.

  • All allergens, including lemons, cause almost similar allergic reactions. The only way to know for sure is by taking an IgE allergy test, which uses a blood sample to determine if you are allergic to lemons or other citrus fruits.

  • If you experience allergy symptoms after ingesting or coming into contact with lemon or lemon products, you should consider allergy testing. Anyone experiencing allergy symptoms can take the lemon allergy test.

  • You don’t need much preparation to take a lemon allergy test. However, it’s important that you consult your doctor before taking the test if you are on certain medications that may alter allergy test results.
