Custom API Integration Expands Blood Glucose Meter Support for Tandem Diabetes Care

Trendsic developed a custom Application Programming Interface (API) that connects Tandem Diabetes Care’s software platform to newly available blood glucose meters — decoding device data so healthcare providers can deliver more accurate, connected patient care.

Trendsic blood glucose meter API integration for Tandem Diabetes Care

Client & Industry

Tandem Diabetes Care® designs insulin pumps that help people with diabetes and their healthcare providers manage blood glucose data and insulin delivery collaboratively.

As new blood glucose meters entered the market, Tandem needed its software platform to support them, enabling providers to pull more accurate readings from the latest devices into their existing patient care systems.

The Challenge

Supporting a new blood glucose meter meant creating a reliable bridge between new device hardware and a software platform patients and providers depend on for accuracy every day.

Challenge 1

Missing Connection to New Meters

Tandem’s platform needed a way to connect to newly released blood glucose meters so providers could bring those readings into the systems they already relied on.

Challenge 2

Undocumented Device Output

Meter results needed to be decoded and verified before that data could be trusted inside a clinical software platform.

Challenge 3

Accuracy Validation

Without a way to test decoded readings against known glucose concentrations, there was no proof the new meter’s data could be trusted for patient care.

Challenge 4

Staying Competitive

Without broader meter support, Tandem risked falling behind as more blood glucose devices and technology entered the market.

The Solution

Trendsic built a custom API around hands-on testing with the meter hardware itself.

Capability 1

Custom Hardware Testing

Trendsic purchased Roche AccuChek Guide® meters and ran controlled tests — applying concentrations of sugar water to blood glucose test strips to generate reliable sample data.

Capability 2

Decoding Device Output

Our team decoded the raw results from the AccuChek Guide® meter, mapping its data format so readings could be read reliably by other systems.

Capability 3

Custom API Development

Using that knowledge, Trendsic created a custom Application Programming Interface connecting the AccuChek Guide® meter to Tandem’s software platform.

Capability 4

Hardware Integration Expertise

The project leveraged Trendsic’s expertise in custom hardware integrations to turn a complex medical device into reliable healthcare software.

This API integration reflects the same approach behind our custom software development services — tailored solutions designed around the systems and devices you already rely on.

Results & Outcomes

Results

  • Expanded Meter Support: Tandem’s software platform gained the ability to read data from newly supported blood glucose meters.
  • More Accurate Patient Data: Decoded, validated readings flow directly into the platform providers already use.
  • Stronger Competitive Position: Supporting a broader range of meters allows Tandem to offer more products and services to healthcare providers.

Other Benefits

  • Improved Patient Care: Providers get a more complete, connected view of patient blood glucose data.
  • Repeatable Integration Process: Purchase the device, generate test data, decode the output, build the API — a proven approach for future meter integrations.
  • Demonstrated Reliability: The successful collaboration reinforced Trendsic’s track record for high-quality, comprehensive solutions.

Technologies & Approach
