First, you want to find out what type of testing do you need to do. US doctors prescribe various skin & blood tests in the US to determinate presence of allergic reaction allergic reaction in human bodies to small amounts of food. These vary by the body reaction:

Age of diagnosisCan appear at any ageCan appear at any ageVaries, but lactose intolerance is most likely in adults.
Prevalence1–3% of adults; 5–10% of childrenUncertain but suspected to be common15–20% of the adult population
Can you get rid of it?Kids may outgrow milk, egg, soy and wheat allergiesMay be able to consume a food again without symptoms after you avoid it for several months and address any underlying issuesCan minimize symptoms by limiting or avoiding problem foods in the long term

What’s the difference between food sensitivity, food intolerance and food allergy body reaction?

Your immune system is your best body’s defense against invaders like bacteria, fungus, or the common cold virus. You have a food allergy when your immune system identifies a protein in what you eat as an invader, and reacts by producing antibodies to fight it. The most common is an immunoglobulin E (IgE)-mediated reaction. IgEs are allergic antibodies, that cause an immediate reaction when chemicals, like histamine from cells, are released.

Food allergy symptoms


The most common food allergy signs and symptoms include:

  • Tingling or itching in the mouth
  • Swelling of the lips, face, tongue and throat or other parts of the body due to immune response
  • Abdominal pain, diarrhea, nausea or vomiting
  • Hives, itching or eczema
  • Wheezing, nasal congestion or trouble breathing
  • Dizziness, lightheadedness or fainting


In some people, a food allergy can trigger a severe allergic reaction called anaphylaxis. This can cause life-threatening signs and symptoms, including:

  • Constriction and tightening of the airways
  • A swollen throat or the sensation of a lump in your throat that makes it difficult to breathe
  • Shock with a severe drop in blood pressure
  • Rapid pulse
  • Dizziness, lightheadedness or loss of consciousness

Emergency treatment is critical for anaphylaxis. Untreated, anaphylaxis can cause a coma or even death. If you suffer any of these symptoms please call 911.

When to see a doctor if you think you might have food allergic reaction

See a doctor or allergist if you have food allergy symptoms shortly after eating. If possible, see your doctor when the allergic reaction is occurring. This will help your doctor make a diagnosis

Food sensitivities symptoms

In almost all cases, food sensitivities are not life-threatening. These are food intolerances that are not immune-mediated. Instead they’re caused by an inability digest and process food.

Food allergy test costs

For a patient without insurance, the patient can expect to pay $150-$300 for a consultation with an allergist plus anywhere for:

  • Skin prick allergy test: $60-$280
  • Intradermal allergy test price: – $80 – $400
  • Blood test for allergy cost: $200 – $1,000
  • Patch test for allergy cost: usually $5-15 per allergen which translates to $200 – $600

Most allergy testing is usually covered by insurance. However a high deductible patient is expected to pay the full list price before the insurance kick-in.

Note, if you don’t have any money and you can always try elimination diet, where you simplify your specific food intake to rice or other basic meal and slowly introduce potential allergens to identify the food that is causing you food sensitivities. Please always consult your doctor as necessary.

Please note, in a case of serious allergy doctors might recommend immunotherapy, which can cost up to $4K for a full procedure. Treatment usually takes up to 3-5 years.

Food sensitivity test results costs

In most cases as these are not considered medical diagnosis and as a result they tend to to be covered by insurance. The prices are very similar, the blood test can be around $200-$600. At home tests start at $60-150.

Where can you get tested for food sensitivity?

Your allergist might offer an onsite test for skin prick, intradermal or patch test allergy procedures. If you are suggested a blood test, then you might use a local lab facility to get yourself tested.

Tips for getting an affordable allergy sensitivity test

  • Shop around for the best true allergy test price
  • Don’t hesitate to ask for discounts for lab testing services if you pay in cash
  • Ask about all the fees for your test, does it include a follow-on session with allergologist?
  • Don’t follow your doctor direction blindly and first check if your insurance covers that facility, if you haven’t met your yearly deductible, you might be better of paying out of pocket
