Start with the exact model.
The regional VivaChek CGM page refers to SIBIONICS GS1. Treat that as a starting point for checking the device in front of you, rather than assuming every product using the VivaChek name has the same manufacturer or specifications.
For an individual purchase, match the packaging, instructions, app and local seller. For business research, also identify the legal manufacturer and the party responsible for your market.

What the regional page says about GS1
The source below describes a 14-day sensor, glucose updates every five minutes and a 60-minute warm-up when pairing. These are the regional website’s product descriptions, not results from our own testing or confirmation for every market version.
Before relying on a specification, match the supplied instructions to your exact product. See the regional product page and FAQ for its full wording.
A practical product document checklist
| What to check | Why it matters |
|---|---|
| Model name and reference | Compare like with like. A brand name alone is not a complete product identifier. |
| Instructions and version | Keep the document language, revision and intended market together. |
| Wear period and operating limits | Use the instructions for the exact version supplied to you. |
| App and phone compatibility | Check the app publisher, country availability and supported operating systems. |
| Manufacturer and local representative | Use labeling and regulatory documentation to establish the legal entities. |
| Warranty and replacement | Ask who handles a failed sensor and which proof of purchase is required. |
Separate specifications from purchase promises
A published specification does not establish stock, a delivery date or approval in your country. A quote should identify the exact product and the local terms separately.
This guide does not report hands-on testing or provide treatment instructions. If you already use a device, follow its supplied instructions and consult your healthcare professional about your care.
