SIGNOS INDICATIONS: The Signos Glucose Monitoring System is an over-the-counter (OTC) mobile device application that receives data from an integrated Continuous Glucose Monitor (iCGM) sensor and is intended to continuously measure, record, analyze, and display glucose values in people 18 years and older not on insulin. The Signos Glucose Monitoring System helps to detect normal (euglycemic) and low or high (dysglycemic) glucose levels. The Signos Glucose Monitoring System may also help the user better understand how lifestyle and behavior modification, including diet and exercise, impact glucose excursions. This information may be useful in helping users to maintain a healthy weight.
The user is not intended to take medical action based on the device output without consultation with a qualified healthcare professional.
See user guide for important warnings and precautions.
STELO IMPORTANT INFORMATION: Consult your healthcare provider before making any medication adjustments based on your sensor readings and do not take any other medical action based on your sensor readings without consulting your healthcare provider. Do not use if you have problematic hypoglycemia. Failure to use Stelo and its components according to the instructions for use provided and to properly consider all indications, contraindications, warnings, and cautions in those instructions for use may result in you missing a severe hypoglycemia (low blood glucose) or hyperglycemia (high blood glucose) occurrence. If your sensor readings are not consistent with your symptoms, a blood glucose meter may be an option as needed and consult your healthcare provider. Seek medical advice and attention when appropriate, including before making any medication adjustments and/or for any medical emergency.
