Summary

YorkTest Laboratories tests for intolerances in food and drink using IgG antibodies. Most customers felt that this was an accurate and helpful method, helping them relieve chronic conditions. The price is a bit higher than others but this is most likely due to it being a more involved test.

This review is written with the intent to be as unbiased as possible. However, it represents the opinion of an individual reviewer and is therefore subjective. Furthermore, at Nebula Genomics we seek to educate the public about the benefits of Whole Genome Sequencing. Information about our Whole Genome Sequencing DNA test is therefore incorporated into the review.

Introduction

YorkTest Laboratories is a food intolerance testing company that uses a blood test to analyze the body’s IgG reaction to ingredients. Initially, it covered 158 foods. Now, it tests for over 200 foods and drinks. It offers a test for adults and a separate one for children over the age of two.

The test addresses issues like IBS, migraines, bloating, tiredness, and skin conditions. After they receive the results, customers can also choose to add a 30-minute consultation with a nutritional therapist for an extra fee.

Review of the Science Behind YorkTest Laboratories

YorkTest Laboratories has over 40 years of excellence in laboratory diagnostic testing and is a leading provider of food and drink-specific IgG antibody testing programs. It notes that it uses personalized information and support to improve customer health.

The company constantly reviews its procedures based on cutting-edge research and routinely reviews ongoing research and publishes relevant papers and surveys.

YorkTest Laboratories science
YorkTest Laboratories science

Unlike other food sensitivity sites that use hair samples and bioresonance technology, YorkTest Laboratories uses a blood sample to analyze IgG, the body’s antibody reaction to proteins in foods. YorkTest notes that hair samples are not backed by science while its immune reaction tests are. The results are based on food-specific IgG antibodies and their presence helps identify foods to which a person may be sensitive.

YorkTest Laboratories measures all four subtypes of IgG (1-4) and notes these in its results. IgG1, IgG2 and IgG3 can cause inflammation which could contribute to symptoms. On the other hand, IgG4 is only present in low levels and does not meaningfully contribute directly to inflammation.

This is one type of test used as a starting point for an elimination diet, the process of removing foods and monitoring systems to help identify a sensitivity. Customers can then find alternatives such as substituting almond milk for dairy milk.

Review of YorkTest Laboratories Products

YorkTest Laboratories features affordable sensitivity tests that customers can take at home. Currently, there are two distinct products: one for adults and one for children over the age of two. Customers can also purchase bundles of either two adult tests (Couples) and one adult and one child test (Parent and Child).

The company also offers a nutritional therapist consultation, which must be purchased separately. This is a 30-minute discussion to go over your food sensitivity results in detail.

It appears that the company also once sold allergy, health, and food and drink scan tests but these products are no longer available on the website.

Premium Food Sensitivity Test

The YorkTest Laboratory Premium Food Sensitivity test is the company’s flagship product. It analyzes IgG reactions to over 200 food and drink ingredients and comes with a results guidebook with a food and drinks diary. 

Customers must be 18 years or older to take this test.

The goal is to optimize its customer’s lives by identifying which foods they are reacting negatively to and removing them from daily intake. This often leads to realizing the need for things like gluten free or dairy free diets.

Different from other tests on the market, the YorkTest Laboratories test measures all four subtypes of food-specific IgG, which is essential as all the different food-specific IgG reactions are detected. Taking this test can help users take control of their overall health by removing ingredients that the immune system in the gut has to react to. Many confirmed that it had a positive impact on their health.

Junior Food Sensitivity Test

This test is exclusively for children between the ages of 2-17. With this test, parents optimize their children’s diet by identifying food they react to.

The website provides a detailed list of the various items it tests.

Sample items tested for
Sample items tested for

Overall, it assesses children’s IgG reaction to more than 100 food substances and includes color-coded results and nutritional post-test support. The latter includes a results guidebook with a food and drinks diary and a formal letter to the child’s school on request.

Some of the items tested include cow’s milk, egg yolks, and egg whites.

Review of Taking a YorkTest Laboratories Test

After ordering the test, the company sends the kit with instructions. The kit includes a cleansing wipe for your finger, two lancets (single-use), an absorbent wand, a secure container for the wand, and your customer details form.

The company advertises the test as quick, simple and pain-free. Customers collect a blood sample by using the provided lancets to create a finger prick and collecting 2-3 drops of blood on the absorbent wand until it is saturated.

Then, customers send the sample back to the lab. Once it arrives, customers will receive their results within 7 days. Results include a traffic light-style guide to the level of food and drink intolerances.

Review of YorkTest Laboratories Cost

YorkTest Laboratories tests are comparable to similar tests on the market. The prices are slightly higher for the amount of items tested but it should be noted that this company uses an immune blood test rather than hair samples. Currently, the company features a 30% discount for their holiday sale.

  • Junior: $142 ($99)
  • Couples: $269 ($188)
  • Parent and Child: $269 ($188)

Review of YorkTest Laboratories Report

Like most sensitivity tests, YorkTest Laboratories uses color coding to help users easily identify food intolerances. It’s a personalized report in which red designates the most reactive items, orange designates borderline reaction items, and green is no reactivity.

Customers receive their report in their Wellness Hub account and can download it at any time.

The company claims that unlike other food sensitivity tests on the market, its tests go into deep testing to discover the issue. For example, the Premium Food Sensitivity Test measures all four subtypes of food-specific IgG (1-4) which help to detect all possible varying food-specific IgG reactions. The tests are accurate, with a reproducibility rate of over 98%.

Nebula Genomics

YorkTest Laboratories analyzes immune responses to determine food and drink sensitivity. The positive customer reviews relative to other sensitivity companies may reflect the value of this clinically tested methodology. 

Another way to investigate undiagnosed symptoms is to analyze your genome for genetic predispositions. These results could inform you to conditions you are at a higher risk for, allowing you to focus on certain things related to diet.

Nebula Genomics is one of the ways users can get more insight into their health. This test uses 30x whole genome sequencing, which decodes all 20,000 genes in the human genome.

Other genetic testing sites limit their results to less than 0.2% – relating only the conditions they deem necessary. With Nebula, results also come with ancestry reporting and genome exploration tools. This gives our customers the most control over their data.

For only $299 or less, customers will get access to their entire genome, allowing them to continue to ask more questions as more research is conducted.
