Patented U-Smell-It ® Olfactory Test

Rapid, Robust & Repeatable

U-Smell-It smell screening test

Our Science Based Mission

Our mission for loss of smell and loss of taste with u-Smell-it test

We have brought together a global team of scientists and forged partnerships with industry leaders to develop a robust, rapid, and repeatable smell test.


Our goal is to utilize a quantitative olfactory test for enhanced personal safety and early detection of smell loss, which can be associated with diverse diseases including neurological disease, cardiovascular disease, infectious disease, traumatic brain injury, and other conditions*.


Validation comes from science.

Your sense of smell is an essential early warning system

Army smell test


You may smell SMOKE before seeing the fire to take quicker action.



Unseen electrical fires start behind walls and in vehicles but many can be smelled by the acrid burning plastic.



Your nose can alert you to hazardous substances.



Gas leaks can be lethal. Odorous compounds are added to help you smell the danger.



Food may look fine, but smell ‘off’ due to bacterial or fungal contamination.

But with a fully operational olfactory sense can you rely on this life-saving early warning system.

5 Key Features and Benefits

5 Key Features and Benefits of the U-Smell-It® Test

Warning Signals | Diseases & Conditions Linked with Loss of Smell Include

Traumatic Brain Injury (TBI):

Severe head trauma can serve as an early warning sign, triggering loss or altered sense of smell as a prodromal symptom.


Cardiovascular Disease (CVD):

Early stages of CVD can exhibit olfactory dysfunction, including the loss of smell, offering a potential prodromal indicator of underlying vascular damage.


Infectious Diseases:

Various infectious diseases, including respiratory viruses like coronaviruses, can cause acute loss of smell, while those with Long COVID may experience loss or distorted (parosmia) smell.


Alzheimer’s Disease:

Olfactory dysfunction, such as loss of smell, often presents as an early prodromal symptom in individuals at risk of developing Alzheimer’s disease.


Parkinson’s Disease:

Diminished sense of smell acts as an early warning sign, preceding motor symptoms, and serving as a prodromal indication of Parkinson’s disease.


Chronic Rhinosinusitis:

Long-lasting inflammation in the nasal passages and sinuses can manifest as an early warning sign, foretelling a potential decline in the sense of smell.


Note that this list is not  comprehensive, and there are other conditions or factors that can also impact the sense of smell, including aging.  As smell loss can be due to multiple factors it should not be used alone to diagnose a specific disease or condition.  Further, the absence of an abnormal test result does not rule out diseases or other conditions. A person with olfactory dysfunction should consult with a healthcare professional.
