What Research shows


u-Smell-it test is a Pre-Corona test. Research shows that our nose is a powerful secret weapon to help identify COVID-19 as up to 85% of people infected with the coronavirus experience loss of smell.1

Identifying loss of smell, aka anosmia, is a 5-10 times more specific indicator than a temperature test.2 3

This is due to the nature of the SARS-CoV-2 coronavirus, which binds ACE2 Receptors that are enriched -500 fold in top of the nose.4

Thus a unique feature of COVID-19 is a loss of smell even without a stuffy or runny nose that is typical of the flu.5

Need Smell Test?


But do we need a smell test (aka a chemosensory test)? Yes!

When any of our 5 senses are altered to properly determine this requires a sensitive and standardized test, such as a vision test or hearing test -especially when there is only partial alteration. Same with smell – this requires a quantitative smell (aka olfactory) test. For the loss of smell maybe very subtle and not noticed. There can be other effects such as foods may
taste different.

Our u-Smell-it cards are designed to detect what is hidden and are noticed and optimized. To help detect for Covid-19 induced loss of smell in a format that is fast, inexpensive, accurate and even fun.

This is not a diagnostic test rather an indicator that you may have loss of smell and may give false positive or negative results.

Do you smell it?

Oxford Academic Posted; Objective Sensory Testing Methods Reveal a Higher Prevalence of Olfactory Loss in COVID-19–Positive Patients Compared to Subjective Methods

Abstract; Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has currently infected over 6.5 million people worldwide. In response to the pandemic, numerous studies have tried to identify the causes and symptoms of the disease. Emerging evidence supports recently acquired anosmia (complete loss of smell) and hyposmia (partial loss of […]
