"Smell loss is one of the earliest and strongest predictors of SARS-CoV-2 infection,

Compared with objective testing, subjective olfactory assessments significantly underreport olfactory dysfunction.”

– Carol Yan, MD – University of California San Diego

“One thing that’s become very important with COVID-19 is that there’s no single symptom that is universal for everyone who has the disease, but one of the most common is smell loss, especially early, sudden smell loss.

There are a growing number of studies that suggest 50% to 70% of individuals with COVID-19, even if they don’t have another symptom, are experiencing smell loss”

– Steven Munger, Director of the University of Florida’s Center of Smell and Taste







As COVID-19 cases continue to climb, a new study by researchers at UC San Diego suggests there is a cheap and easy way to screen people for the virus: a smell test.

The researchers found that a scratch-and-sniff test featuring a single scent was able to detect 75 percent of people infected with COVID compared to a hospital-grade diagnostic, according to a study published.

SniffDeez are “Symptom” tests for coronavirus. 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. Identifying loss of smell, aka anosmia, is up to 27x times more specific indicator than a temperature test.

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. 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.

Early Detection Of Smell Loss

The SniffDeez smell test was developed by an international research team to quickly and easily detect loss of the sense of smell. Various studies have shown that the loss of the sense of smell can be a sign of illness.

With the SniffDeez smell test you are able to rapidly test your sense of smell easily and immediately detect & react to any possible change.

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 SniffDeez 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.
