Abstract
A method and system of predicting the level of the HbA1C component of glycosylated haemoglobin in a patient's blood. A mathematical model is derived which predicts the behavior of the HbA1C, component level relative to the blood glucose level using previously measured HbA1C and blood glucose levels. The model is updated each time a new HbA1C level is measured using that new measurement and recent new blood glucose level measurements. The updated model is then applied to predict the HbA1C level, between measurements of that level, using measurements of blood glucose level obtained since the last HbA1C measurement.

A method of predicting a level of a glycosylated haemoglobin component in a patient's blood using previously measured blood glucose levels and previously measured glycosylated haemoglobin component levels, the method comprising the steps of:
- deriving a mathematical model of the behavior of the glycosylated haemoglobin component level relative to a newly measured blood glucose level using previously measured blood glucose levels;
- updating the model when a new glycosylated haemoglobin component level is measured using the new glycosylated haemoglobin component level measurement and recent new blood glucose level measurements obtained since the new glycosylated haemoglobin component level measurement;
- and
- applying the mathematical model to predict the glycosylated haemoglobin component level, between measurements of the glycosylated haemoglobin component level, using measurements of the blood glucose level obtained since a last glycosylated haemoglobin component measurement.
A method of predicting the level of a glycosylated haemoglobin component in a patent's blood using previously measured blood glucose levels and previously measured glycosylated haemoglobin component levels, the method comprising the steps of:
- transmitting a blood glucose measurement from a remote station to a central processing station;
- predicting at the central station a glycosylated haemoglobin component level for the patient's blood using said transmitted measurement and a mathematical model of the glycosylated haemoglobin component level relative to blood glucose level;
- and
- transmitting the predicted glycosylated haemoglobin component level from the central station to the remove station.
A system for predicting the level of a glycosylated haemoglobin component in a patient's blood using previously measured blood glucose and glycosylated haemoglobin component levels, the system comprising:
- means for deriving a mathematical model of the behavior of the glycosylated haemoglobin component level relative to the blood glucose level using previously measured levels, and for updating the model when a new glycosylated haemoglobin component level is measured using that new measurement and recent new blood glucose level measurements;
- memory means for storing said model and the updated model and measured blood glucose and glycosylated haemoglobin component levels;
- and
- means for applying the mathematical model to predict the glycosylated haemoglobin component level obtained since the last glycosylated haemoglobin component measurement.
A system for predicting a glycosylated haemoglobin component level of a patient's blood comprising:
- a blood glucose measurement unit;
- a communication device coupled to the blood glucose measurement unit via an interface, the interface adapted to transmit a newly measured blood glucose level to the communication device for transmission;
- and
- a central processing station adapted to receive the transmission of the newly measured blood glucose level from the communication device and estimate the glycosylated haemoglobin component level in the patient's blood using the newly measured blood glucose level, at least one prior glycosylated haemoglobin component level measurement and a precalculated regression coefficient vector.
