Frequently Asked Questions
Everything you need to know about the Yuwell CT3 Continuous Glucose Monitor.
What is the Yuwell CT3 CGM?
The Yuwell CT3 is a continuous glucose monitoring system that tracks your glucose levels in real time, sending updates to your smartphone every 3 minutes. It provides 24/7 insights without finger‑pricks, helping you understand how food, exercise, stress, and sleep affect your glucose.
Is the Yuwell CT3 TGA‑approved in Australia?
Yes. The Yuwell CT3 is TGA‑approved and listed on the Australian Register of Therapeutic Goods (ARTG ID: 521193). This means it meets Australian safety, quality, and performance standards.
Who is the Yuwell CT3 designed for?
The CT3 is ideal for:
- People with Type 1 or Type 2 diabetes
- Individuals who are not eligible for NDSS subsidies
- Prediabetes users
- Athletes and biohackers
- Anyone wanting deeper metabolic insight
If you’ve been relying on a traditional blood glucose meter (BGM), the CT3 offers a far more complete picture of your glucose patterns.
Why is the Yuwell CT3 more affordable than other CGMs?
Most CGMs use disposable all‑in‑one sensors, which makes long‑term use expensive.The CT3 uses a reusable transmitter that lasts up to 2 years, dramatically reducing cost and waste.
This makes it one of the most affordable CGMs for non‑NDSS users in Australia.

Each CT3 sensor lasts 14 days and provides continuous readings every 3 minutes.
How long does the transmitter last?
The transmitter is rechargeable and lasts up to 2 years. It attaches to each new sensor and can be recharged using the included charging stand.
How long is the warm‑up time?
The Yuwell CT3 has a 1‑hour warm‑up period after applying a new sensor.After that, you’ll receive continuous real‑time readings.
How accurate is the Yuwell CT3?
The CT3 has a MARD of 6.9%, which is comparable to leading CGMs. It has been validated in clinical trials and is widely used across the UK and Europe.
How does the CT3 compare to Ottai?
