A Test That Detects Early Smell Loss and Neurologic Disorders

MSP uses advanced technologies to identify unnoticed changes in your ability to accurately smell. Normal ability can change without you ever noticing these slight changes. Sensitivity degradation occurs due to viral infections, they also are early symptoms of Neurological disease.  Concussion and TBI also temporarily cause Olfactory disorders.
Use MSP to rapidly screen for these unnoticed and undiagnosed disorders. Safe, Effective,

60-second, affordable, Insurance covered screening tool.

Can a Concussion Cause Loss of Smell?

It's long been known that people who suffer a major concussion can lose their sense of smell temporarily and also develop affective problems, such as anxiety and depression. Now scientists have found that's true even for people who get a minor concussion. 

Hit your head, lose your sense of smell - ScienceDaily

"Surprisingly, a test of olfactory function is not currently a part of the concussion protocol even though smell loss has been a common occurrence following head injuries. A test of olfactory function and CTE in real time would be a “game-changer” in our understanding of repetitive head injuries. A 5-min smell test given by a single technician could objectively track CTE over time." Science

Loss of Smell Can be a Hallmark Symptom in the Earliest Stages of Many Diseases.

In the 1970s, researchers learned that smell is compromised in neurodegenerative conditions like Alzheimer's diseaseParkinson's diseaseHuntington's disease, and multiple sclerosis (MS). Now, they are discovering that loss of smell can be a hallmark symptom in the earliest stages of many diseases.

"Recent studies of brains from Alzheimer's and Parkinson's disease patients reveal structural and biochemical alterations in regions associated with the sense of smell," says Richard Doty, Ph.D., professor and director of the Smell & Taste Center at the University of Pennsylvania. Loss of smell occurs 90 percent of the time in Parkinson's disease. This is greater than the prevalence of tremors, a cardinal sign of the disorder.

Yet in one study of Parkinson's patients, 72 percent were unaware they had a smell disorder before undergoing standardized testing. Only two out of 34 Alzheimer's disease patients reported suffering from smell and/or taste problems-even though 90 percent of the patients scored lower on standardized smell tests than healthy subjects.

Key Features


  • A PASSED result indicates that you have a normal olfactory function,  while a FAILED indicates that you have an abnormal olfactory function*, highly associated with early viral infection, Neurological disease, Concussion, and TB.

  • Save your PASSED result to wallet.

  • Scannable QR code can be used with PASS validator application.

  • Show PASSED or FAILED for validation of results.

  • Proceed to take the optional COVID-19 Health Screening Questionnaire.

  • A FAILED result will prompt you to seek additional attention from a healthcare provider.

  • A FAILED result will give you the option to receive a FREE at-home PCR test via our National Telehealth providers and Sensiva at-home PCR kits.

*Olfactory dysfunction can be due to other causes including neurodegredation disease, head trauma or other viral infections and this is not to screen or diagnose a specific disease or condition.

Olfactory Disorder & Viral Screening

“The Secret Behind the Science”...

Cells by the olfactory neurons are up to 600x enriched in the ACE2 receptor and it’s where the virus goes first. SARS-Co-V2 enters through your nasal cavity which causes olfactory disorders.


Smell disorders in the early stages are sometimes the only symptom in COVID-19. Most infected people do not notice this symptom unless a test is used that can identify a partial loss of smell (hyposmia). This is important for while some people can notice total smell loss many will not notice hyposmia without an objective and quantitative olfactory test.

Loss of Smell - Key Differentiator

Loss of smell is the differentiator symptom and is not present in flu or allergy.

Olfactory disruption is a prevalent and one of the first indications of COVID-19 infections (day 1-3). This happens before noticeable symptom including fever headache, and diarrhea. A unique feature of COVID-19 is a loss of smell and the ability to understand scents even without a stuffy or runny nose caused by a normal cold or flu.  Fever is not a good indicator of Covid-19 infection. A recent study shows that patients were "found that Covid-19 patients were 27 times more likely than others to have lost their sense of smell. But they were only 2.6 times more likely to have fever or chills...“
