Glucometers Protocol Specifications

This website is intended to provide description of protocols (or "Computer Interface Specifications") for various glucometers.

As few manufacturers publish documentation of their meters' protocols, the majority of the content is produced by reverse engineering the data transmission between meters and PCs, and documenting it.

Reversed Engineered Protocols

See reverse engineering contribution suggestions for details on how to contribute new protocols.

Manufacturer Supplied Documentation

Standards and Common Protocols


CLSI (Clinical and Laboratory Standards Institute) develop and publish protocols that are used by some meter manufacturers.

The two main relevant documents are:

These are proprietary, not freely available standards.

Bluetooth GATT

Many Bluetooth glucometers implement GATT Services, which then reference the following specifications:
