THE SHORT ANSWER
Camera-based wellness tools analyze signals in a video feed to produce informational insights. The results and limitations depend on the tool and its configuration. A scan is not a diagnosis and should not be used to change medication or replace clinical assessment, laboratory tests, or a prescribed measurement device.
What to keep in mind
- Read the instructions that accompany your scan.
- Use the result as context for a conversation.
- Do not treat a reassuring result as a reason to ignore symptoms.
How does camera-based analysis work?
Shen AI, the technology behind the portal’s white-labeled scan, describes using remote photoplethysmography and camera analysis to assess physiological signals. The technology looks at information in the video feed rather than requiring a finger-prick sample. This does not mean it can answer every health question.
How should I approach a scan?
Open the scan within your secure patient portal and follow the displayed setup and positioning guide. Pay attention to the measurement conditions and the tool’s instructions rather than trying to obtain a particular result.
Lighting, position, movement, and the tool’s intended use can matter. Follow the instructions supplied with the experience and repeat a scan only as directed. Read the context provided with any output before drawing conclusions.

What should I avoid inferring?
An informational insight does not establish a diagnosis, prove that a medicine is working, or decide whether you should take one. It also does not replace the measurement method your clinician has asked you to use.
If a result raises a concern, ask your clinician how it should be interpreted. If you feel unwell, seek appropriate care based on your symptoms rather than waiting for another scan or relying on an apparently reassuring number.
Where does Vital Scan fit at TellyMeds?
Vital Scan is part of the patient portal experience, alongside personal care features such as messages, prescriptions, and appointment information. The public website explains the feature; it does not activate your camera or run a scan.
Use your portal’s privacy information and consent flow to understand permissions and how the specific experience handles data. The general description of a technology vendor is not a substitute for the information provided with your account.
