If you have diabetes, checking your blood sugar (also called glucose) is one of the most important things you do every day. It helps you stay healthy and avoid serious problems. In the past, people with diabetes had to use a device that required pricking their fingers to get a drop of blood. But now, technology has made checking blood sugar easier and more advanced.
There are two main types of devices for checking your glucose levels: the glucometer and the CGM (Continuous Glucose Monitor). Both have their own benefits and can help you manage your diabetes better. Choosing the right one depends on things like cost, comfort, and what your doctor recommends.
1. Glucometer: The Classic Blood Sugar Checker
A glucometer is a small device that uses a drop of blood, usually from your fingertip, to check your sugar level. Here’s what you need to know:
- It gives a quick and accurate reading of your blood sugar at the moment you test.
- Many people test several times a day, which helps them understand their overall glucose control.
- These devices are easy to use and are often covered by insurance.
- You might feel pain from finger pricks, but you can ask your doctor about alternate sites like your arm or thigh.

2. CGM: Continuous Glucose Monitor – High-Tech Help
A CGM is a newer device that checks your glucose all day and night. It doesn’t use your blood but instead reads the sugar levels in the fluid under your skin. Here’s how it works:
- A small sensor is placed under your skin, usually on your belly or arm.
- The sensor stays in place with a patch and sends data to a receiver or even to your smartphone.
- Some CGMs also connect to insulin pumps, helping you manage your diabetes more easily.
- Most CGMs show your sugar levels in real-time and even alert you if your glucose goes too high or low.
This technology allows you and your doctor to track your sugar levels over time, making it easier to see patterns and adjust your treatment.
3. Accuracy: Glucometer vs. CGM
Accuracy is very important when managing diabetes. According to the FDA:
- Glucometers in the U.S. are 95% accurate within 15% of actual values.
- CGMs can be affected by things like body chemistry or how they are placed under the skin.
- It’s often best to double-check CGM results with a fingerstick before changing your treatment.
While CGMs are improving, fingerstick tests still provide the most reliable results.
4. Pros and Cons of Both Devices
Glucometer Pros:
- Very accurate.
- Easy to use.
- Usually covered by insurance.
Glucometer Cons:
- Finger pricks can be painful.
- Strips can go bad if not stored properly.
- Extreme temperatures can affect the results.
CGM Pros:
- Fewer finger pricks.
- Tracks your glucose all day and night.
- Sends alerts when glucose is too high or low.
- Helps you and your doctor see your sugar trends clearly.
CGM Cons:
- Can be expensive.
- Needs learning and practice to use correctly.
- Sensors must be replaced regularly.
5. Insurance Coverage: What’s Paid and What’s Not
Insurance coverage can differ from one plan to another:
- Private insurance may cover some devices but not all. It’s important to check with your provider to see what is covered.
- Medicare Part B covers glucometers, test strips, and CGMs for people who use insulin. However, there are rules about which brands are covered and how often supplies are given.
- CGMs are often more expensive, and while more insurance companies are covering them, out-of-pocket costs may still be high.
- Always check if your insurance covers sensor replacements, as this can add to the cost.
Daily News Highlights Tip: Call your insurance company to make sure you understand what’s covered before you buy a device.
Whether you choose a glucometer or a CGM, the most important thing is that you regularly check your blood sugar and follow your diabetes care plan. Both devices can help you stay on track and live a healthier life. With new technology and better support, managing diabetes is becoming easier and more accurate than ever before.
