THE ONE AND ONLY SCREENING TEST YOU NEED
THE SCIENCE
RIGOROUS CLINICAL DATA
Parameters Important for Clinical Use:
- Accuracy validated at 96.4% versus PCR
- Capable of Early Detection as early as 3 days after infection long before any other symptom has appeared
- Features Hyposmia / Anosmia test plus Symptom Questionnaire
- Filters for “infection-suspects”
- Fast & Easy - Anywhere, Anytime, by Anyone
- Registered with FDA, CE, at BfArMand Health Canada
- Has been used globally in many countries
Around 30,000 users tested in 5 clinical trials e.g. in 2 clinical trials where 415 subjects were tested with both Corowell test and PCR at the same time – only one false negative and one false positive.
Sensitivity versus PCR validated in multiple clinical trials with 415 people of 96.4% Corowell is effective at early detection of COVID 19 symptoms as a screening tool and people suspected of infection the earliest than any other test on the market today.

UNDERSTANDING HYPOSMIA
RT-PCR AS AN EARLY DETECTOR OF INFECTION:
Hyposmia (partial loss of the sense of smell) is the most suitable indicator for early COVID-19 detection occurring in up to 87% of those infected in the first 9 days after infection long before any other symptoms develop. Anosmia is the loss of smell and that occurs in about 13% of those infected and occurs in a much later stage of infection when other moderate symptoms are also present.
- Invasive test with discomfort and danger for the young and the elderly.
- Due to very small amount of virus at the beginning of infection, the use of fast RT-PCR of 2 hours (CT20) results in a very high percentage of false negatives.
- It needs machines and time both of which make it very difficult to use as a quick screening tool for those infected.
- It is also an expensive tool requiring training machines, reagents, calibration of machines and perfect execution to ensure accurate results
RAPID ANTIGEN TESTS AS AN EARLY DETECTOR OF INFECTION:
- Due to very small amount of virus at the beginning of infection, the use of antigen test that require a much higher amount of virus ( viral load) at the time of testing have no chance to detect someone at the beginning of infection.
- They are designed for use in people with moderate symptoms to confirm infection. However when used early their detection threshold is not sensitive enough nor granular enough to detect small changes of infection.
- They are idea starting from day 12 to 14 of infection.
Hyposmia (partial loss of the sense of smell) is the most suitable indicator for early COVID-19.
