Top 5 Noninvasive Blood Sugar Monitors Without Finger Pricks in 2025 - Prices & Reviews

Traditional finger prick glucose testing has been vital in managing diabetes, but the discomfort and inconvenience of multiple daily finger sticks have led many to seek alternatives.

Monitoring blood sugar levels remains crucial for effective diabetes care, with frequency depending on your treatment plan and personal health needs.

Factors like stress, illness, and physical activity can cause fluctuations in glucose levels, making reliable and easy monitoring essential.

Recent advancements have introduced innovative, pain-free blood sugar monitors that do not require finger pricks, enhancing convenience and comfort.

Continue reading to discover the best noninvasive glucose monitors available today, and how to decide if these options are right for your health management.

Choosing the Right Glucose Monitor

Whether opting for traditional or noninvasive devices, consider these key points before making your choice:

Insurance Coverage

Start by verifying which monitors and test strips your insurance covers, as this can significantly affect your expenses and device options.

Accuracy

Accurate readings are vital since treatment decisions rely on them. The FDA allows a margin of error within 15%, so choose devices that consistently deliver reliable results.

Display and Accessibility

Choose monitors with clear, easy-to-read displays. Features like backlighting or voice output can assist those with visual impairments.

User-Friendliness

A simple, intuitive device encourages regular use. Avoid meters that require complicated setup or coding.

Portability and Size

Comfort and convenience matter. Compact but easy-to-handle devices are ideal for active lifestyles.

Additional Features

Bluetooth connectivity, data storage, and timestamping can enhance your ability to track and share glucose trends.

2024’s Best Noninvasive Blood Sugar Monitors

FreeStyle Libre 2

FDA-approved since 2017, the FreeStyle Libre 2 uses a sensor worn on the upper arm to measure glucose via interstitial fluid, eliminating the need for finger pricks.

The sensor lasts 14 days and glucose levels are read by scanning the sensor with a reader or smartphone app multiple times daily.

The Libre 2 adds alert features for high or low glucose levels, making it suitable for both adults and children.

While generally well-received, some users report occasional inaccuracies and potential skin irritation.

Eversense CGM

Approved in 2019, Eversense is a unique continuous glucose monitor implanted under the skin, paired with a wearable transmitter that sends data to your smartphone every 5 minutes.

The sensor lasts up to 90 days but requires a healthcare professional for insertion and removal.

Sunlight sensitivity of the transmitter is a consideration when choosing the sensor location.

Dexcom G6

Launched in 2018, the Dexcom G6 offers real-time glucose monitoring for users aged 2 and up with a sensor worn on the abdomen lasting 10 days.

This water-resistant device transmits glucose data every 5 minutes to smartphones, smartwatches, and other compatible devices.

Users praise its accuracy but note the inconvenience of frequent sensor replacements.

Guardian Connect System

Medtronic's Guardian Connect, FDA-approved in 2018, features a sensor and transmitter worn on the abdomen or arm, sending glucose readings every 5 minutes to a smartphone app.

It emphasizes "time in range" metrics to help users maintain optimal glucose control and is approved for those aged 14 and older.

D-Base by DiaMonTech

D-Base introduces a groundbreaking approach using infrared laser technology to measure glucose levels through the skin by detecting heat changes.

While preclinical results show accuracy comparable to test strips, the device is large and stationary, limiting portability and availability as it is still in development.

Emerging Technologies and Future Devices

Other innovative meters like GlucoTrack, which measures glucose via the earlobe, are in development but not yet FDA-approved.

Although smartwatches and contact lenses with glucose monitoring capabilities are popular ideas, none currently provide reliable blood sugar measurement.

Tips for Easier Glucose Monitoring

• Always wash hands with soap and water before testing for accurate results; avoid hand sanitizer before finger sticks.
• Clean and dry skin thoroughly before sensor insertion.
• Contact your healthcare provider if you experience persistent skin irritation from sensors.
• Replace sensors according to manufacturer recommendations.
• Use the side of the fingertip near the nail to reduce pain when finger pricking.
• Keep a traditional meter handy to verify readings if symptoms don’t match sensor data.

FAQs about Noninvasive Glucose Monitoring

Is there a glucose meter that doesn't require blood?

Continuous Glucose Monitors (CGMs) measure glucose through interstitial fluid just beneath the skin, eliminating the need for blood samples.

Are noninvasive glucose meters effective?

Noninvasive meters like CGMs provide convenient and reasonably accurate glucose monitoring, though traditional meters may still be more precise.

Is there a smartwatch that monitors blood sugar?

Some CGMs can sync data to smartwatches, but no smartwatch currently measures blood sugar directly.

What are the costs of glucose monitors?

CGMs require a prescription and are often covered by insurance and Medicare, though out-of-pocket costs can vary. Without insurance, monthly costs may exceed $100. Discounts and coupons may be available through manufacturers or pharmacies.

Final Thoughts

While traditional glucose meters remain widely used, noninvasive options are rapidly evolving, offering painless and user-friendly alternatives for blood sugar monitoring.

Consult your healthcare provider to determine if a noninvasive glucose monitor suits your lifestyle and health needs, enabling more comfortable and consistent diabetes management.
