US Food Intolerance

Environmental Pledge

We are serious about leading the industry with our environmental standards.

Our USA-based testing laboratories and partners are fully equipped with the latest eco-friendly testing machines and practices. We also have a unified recycling culture, strategically placing recycling points throughout our building.

As a business in the health and wellbeing sector, our company has the opportunity to leverage technology to lower not only our carbon footprint but also that of our supply chain; that’s why we don’t mail a testing kit or send hair samples to laboratories outside the USA.

As part of a worldwide organization, our goal is to become net zero by 2035. Our objective is that by achieving net-zero status, we may encourage other businesses in our industry to do the same and contribute to building a more sustainable future for everyone.

FAQs

You are purchasing a food intolerance test with no at-home testing kit. You must follow the ‘How it Works’ instructions to receive your test results. Simply place your hair sample in a secure, sealable bag along with a completed test submission form and mail to: US Intolerance Testing LLC, 8480 Baltimore National Pike STE – 3210 #212, Ellicott City, MD, 21043 Note we cannot be responsible for undercharged mailed packages. You should receive your results within five working days of receiving your hair sample at the US laboratory. If you haven’t received a confirmation email, please check your spam or junk folder.

No trouble. Please include handwritten order details, including First & Last Name, Order Number and Order Date. Simply place your hair sample in a secure, sealable bag along with a completed test submission form and mail to: US Intolerance Testing LLC, 8480 Baltimore National Pike STE – 3210 #212, Ellicott City, MD, 21043. Note, we cannot be responsible for undercharged mailed packages. You should receive your results within five working days of receiving your hair sample at the US laboratory. If you haven’t received a confirmation email, please check your spam or junk folder.

Your test includes a food intolerance test, one nutritional deficiency test, and one metal test. Your intolerance test results include all items with a score of 85% or higher. After completing thousands of tests, we now know that 85% is the turning point where symptoms begin to develop into an intolerance.

In addition to being less invasive and significantly cheaper, your last meal may affect the results of a blood sample, whereas a hair sample has the information stored for a more extended period and reflects a broader time frame.

The safest way to take a hair sample is by asking someone to help you. First, brush your hair upwards to easily access the hair roots and the back of your head. Hold a small amount of hair between your finger and thumb, and cut the hair as close to the scalp as possible (without pulling any blood). If you do not have someone to help you, please use a mirror to avoid accidentally hurting yourself.

When your order is completed, instructions will be sent to your email along with your receipt (i.e., we will not send test kits). Put 4–5 hair strands from your scalp in an envelope along with a completed Test Submission Form (instructions are emailed).

No, we test the composition of the hair sample, so hair dye will not affect your test results.

Five individual hair strands. No clumps of hair, please.

There is quite a big difference between being allergic, intolerant, or hypersensitive to a substance; however, the symptoms often resemble each other. It may feel equally bad for those who get ill from their diet. Our results will shed light on what intolerances you might have, such as which ingredients to avoid. Intolerances may pass over time, while an allergy lasts for life.

Unfortunately, we don’t recommend the test for anyone under 6. Younger children still need to build up their tolerance levels, which can give false lab results.
