Pros and Cons


  • Allergen panel covers nearly 100% of the globally relevant allergens 
  • Food intolerance test includes 286 food antigens
  • Scientifically backed and does not include unpleasant procedures (e.g., skin tests) or scientifically unfounded food sensitivity tests (e.g., testing of hair samples)
  • More results than competitors


  • The test kit is not a substitute for medical advice or treatment
  • Skin prick may still be uncomfortable for some


7DROPS offers home testing kits that allow customers to test for allergies and food intolerances. Customers can choose either an allergy test or an intolerance test or purchase a single test that includes both.

The goal of 7DROPS is to improve health and quality of life. In a word, the company claims that people will no longer need to wait for referrals or pay for overpriced and frivolous tests that only give an incomplete or false picture of sensitivities. It is also the only at-home test covering 99% of relevant allergy triggers.

This test is for people who want to confirm previous allergy test and/or food intolerance test results, see if immunoglobulin E (IgE) and/or immunoglobulin G (IgG) levels have decreased over time; or for those looking to get tested for allergies and food intolerances for the first time before seeing a specialist.

Overall, the tests analyze 295 allergies and 286 food intolerances.

Biologist Christian Harwanegg founded the company. He worked for the leading companies in immunodiagnostics for over a decade before founding his own med-tech business MacroArray Diagnostics (MADx) in 2016. The MADx team comprises more than 40 employees, including specialists in research, development, production, engineering, marketing, product management, and sales.

The test is suitable for all ages and is available in all states, excluding New York.

Food and environmental sensitivities are just one aspect of overall health! Another view is through genetic predispositions.

The Science Behind 7DROPS

At this time, its approach is based on the latest scientific findings and state-of-the-art-technology.

Using in vitro molecular diagnostics to test a panel of 117 allergen extracts and 178 molecular allergens, 7DROPS offers the most extensive panel of molecular allergens compared to other IgE allergy tests on the market. Using molecular allergens provides a more precise risk assessment, complete resolution of possible cross-reactivities, indication for immunotherapy, and differentiated dietary recommendations.

7DROPS uses both allergen extracts and molecular allergens in their testing methodology. Allergen extracts are used where molecular allergens are not well-characterized or are redundant due to high cross-reactivity. In contrast, molecular allergens are used in cases when allergen extracts are unstable.

This combination ensures the most accurate profiling of a patient’s sensitization status, the first step to developing a type I allergy. To put it another way, it is the process by which the immune system recognizes a new allergen and produces IgE antibodies.

Once the lab report is uploaded to the secure 7 Drops platform, patients can consult with their allergy specialist or nutritionist to devise individualized therapeutic measures, including elimination diets.

Allergy test

This home allergy test helps customers discover allergies they may react to. It includes food allergies as well as those related to things like dust, pollen, and more. In brief, it uses a few drops of blood to measure the body’s total IgE (tlgE) indicating if an allergy is likely, possible or unlikely. 

It also measures Specific IgE (sIgE) against 295 allergen extracts and molecular allergens to help identify what is causing the allergy. 

Allergy symptoms include:

  • hay fever 
  • skin rash (hives & eczema)
  • oral allergy syndrome (tingly lips, mouth & throat)
  • nausea
  • stomach pain
  • diarrhea
  • vomiting
  • allergic asthma & trouble breathing
  • anaphylaxis

Food intolerance test

This type of testing helps customers discover potential food sensitivities. To this end, it uses a food drops of blood to measure specific IgG levels against 286 food antigens from 13 different food groups (including basic and novel foods). It may be able to separate issues from conditions such as irritable bowel syndrome

IgG is an antibody that makes up 75% of human blood serum. Markedly, it signifies memory through exposure to a food.

Symptoms include:

  • bloating
  • stomach pain
  • nausea
  • diarrhea
  • joint pain
  • headaches
  • nervousness & irritability

Allergy & food intolerance test

This test is a combination of the allergy and intolerance tests that analyzes the sample for all 295 allergens as well as 286 food intolerance triggers.

Review of Taking a 7DROPS Test

To take a 7DROPS test customers will order the kit online. The test kits contain:

  • 1 blood sample tube
  • 4 alcohol pads 
  • 3 lancets 
  • 1 transport tube 
  • 1 prepaid return envelope 
  • Instructions 

Customers follow the enclosed instructions to collect a small amount (500 μL) of blood using a small finger prick, a process much simpler than blood draws. Then, they return the sample to the lab using the prepaid envelope. Equally important, customers should return their collected blood sample promptly to avoid having the sample go bad.

The company returns the medically checked results, including personalized recommendations, in the secure online platform. Then, results are usually ready in approximately 10 business days after the sample is mailed.

Review of 7DROPS Cost

The individual tests are around $200 each. There is a discount when buying a combination test. 

  • Allergy Test: $179
  • Food Intolerance Test: $189
  • Allergy & Food Intolerance Test: $259

Customers can also get a reduced price when they buy 2 or more testing kits.

Review of 7DROPS Report

The reports provide different information based on whether the customer is testing for allergies or food intolerances. 

Allergy test

The first part of the report includes the patient information. 

Subsequently, the results for this test start in the second section, with a summary of detectable sensitivities in the blood sample. Specifically, it will highlight the highest measured IgE concentration per allergen group (i.e., pollen, mites, insect venoms, etc.). These reactivies range from “no reactivity to allergen” to “very high reactivity to allergen” on a scale:

  • 0 (<0.3 kUA/L) Negative or uncertain
  • 1 (0.3-1 kUA/L) Low IgE level
  • 2 (1-5 kUA/L) Moderate IgE level
  • 3 (5-15 kUA/L) High IgE level
  • 4 (> 15 kUA/L) Very high IgE level

The higher the IgE level, the greater the potential for an allergic reaction. The number of tested allergen sources will also be listed.

Sample allergy report

The third section is a detailed report on IgE antibody concentration for every allergen within the respective allergen group. Specifically, information includes allergen name, type, specific allergen name, function, and IgE concentration. The scaling system is also the same as in the first section. 

Furthermore, this section includes total IgE, a list of all the allergens tested, and their perspective groups.

Finally, the fourth section is an interpretation summary. It includes personalized interpretations powered by proprietary software. These results also include information related to various therapy options.

Given that allergies can lead to life threatening reactions, patients are encouraged to talk about with their doctors to diagnose a true food allergy and manage treatment.

Food intolerance test

The basic foundation of this report is similar to the allergy test.

The first section contains patient information.

Then, the second section contains summary information on IgG concentration divided into 14 food antigen groups: milk & egg, meat, fish & seafood, cereals & seeds, nuts, legumes, fruits, vegetables, spices, edible mushrooms, novel foods, coffee & tea, and others. These reactivies range from “low reactiving” to “high reactivity” on a scale:

  • 0 (0-9.99 μg/mL) low IgG reactivity
  • 2 (10-19.99 μg/mL) intermediate IgG reactivity
  • 3 (>20 μg/mL) high IgG reactivity

The next section provides detailed results on the IgG concentration for every food antigen tested. In like fashion, it uses the same scale as the previous section. Information includes antigen name, IgG concentration, and level of reactivity. Therefore, these results let customers see the specific foods or ingredients that may be causing their symptoms. 

Finally, the last part shows the number of food allergens tested and how they were divided into groups. Equally important, the company recommends that anyone concerned about their results should consult their doctor or registered dietitian.

Review of 7DROPS Privacy Privacy

The company collects personal information when a user creates an account, registers for a test kit, or subscribes to their newsletter. Markedly, it shares personal information, including test results, with third party labs processing the test and physicians who approve each test and review the results.

Information may also be shared with service providers, in connection with a sale or liquidation of the business, and when required by law.

Other 7DROPS Reviews

There are no reviews on 7 drops on Amazon, BBB, or TrustPilot. 

Reviews on the three test types can only be found on the company’s website. As a result, these ratings are all between 4 and 5 stars. 

For example, customers praised the ease of testing and quickness of the results. Many also made comments about suffering symptoms and having only suspicions of what was causing them. They credit 7DROPS with giving them insights and helping them eventually resolve these issues.
