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.

Standards and Common Protocols

CLSI

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

The two main relevant documents are:

• Specification for Low-Level Protocol to Transfer Messages Between Clinical Laboratory Instruments and Computer Systems, 2nd Edition (LIS01-A2)
• Specification for Transferring Information Between Clinical Laboratory Instruments and Information Systems, 2nd Edition (LIS02-A2)

These are proprietary, not freely available standards.

Bluetooth GATT

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

• Glucose Profile (GLP) 1.0.
• Glucose Service (GLS) 1.0.
• Continuous Glucose Monitoring Profile (CGMP) 1.0.1
• Continuous Glucose Monitoring Service (CGMS) 1.0.1
