WELLNESS
The Wellness market offers a lower bar for initial market entry. The FDA describes "low risk general wellness" products that promote, track, or encourage choices that help living well with diabetes. It must be non-invasive, and present a low risk to users.
Glucose Monitor
-
A Wellness glucose monitor could use a small sample of saliva to show whether glucose levels are in range
-
This could be a simplified technique for diabetics who do not want to worry about numbers, or pre-diabetics who just want to know if their glucose levels are spiking
-
Such a Wellness product would be sold over-the-counter at major drug stores
Lactate Sensor
-
Lactate threshold is a measure of muscle and cardiovascular fitness, and is used by athletes and in cardiac rehabilitation
-
The conventional lactate threshold test requires collecting blood via 6-12 fingersticks during a 20-minute exercise
-
Biosense successfully showed a correlation between blood-based and saliva-based lactate threshold testing
