Method and system for determining the difference between pre-prandial and post-prandial blood glucose values
View Patent ↗A method and system is disclosed that enables a less error-prone and preferably automatic assignment of pre-prandial and post-prandial blood glucose values associated with a meal to improve determining the difference between pre-prandial and post-prandial blood glucose measurements as follows. Blood glucose measurements are read and provided with a relative or absolute time mark and labeled as pre-prandial and reading out post-prandial blood glucose measurements provided with a relative or absolute time mark from the memory of a blood glucose measuring instrument. The chronological sequence of the blood glucose measurements labeled as pre-prandial are determined. The post-prandial blood glucose measurements that correspond to each of the pre-prandial blood glucose measurements are determined by applying a time selection criterion. The difference between corresponding pre-prandial and post-prandial blood glucose measurements is determined. The difference values are displayed that have improved diagnostic value.
1. A method for determining the difference between pre-prandial and post-prandial blood glucose measurements, comprising the steps:
i) reading out blood glucose measurements provided with a relative or absolute time mark and labeled as pre-prandial and reading out other blood glucose measurements provided with a relative or absolute time mark from the memory of a blood glucose measuring instrument;
ii) determining the chronological sequence of the blood glucose measurements labeled as pre-prandial;
iii) determining the post-prandial blood glucose measurement from the other blood glucose measurements that pairs with each of the labeled pre-prandial blood glucose measurements by applying a time selection criterion;
iv) determining difference values between corresponding pairs of pre-prandial and post-prandial blood glucose measurements; and
v) displaying the difference values.
2. The method according to claim 1 , wherein
allocating to time categories corresponding to meals the blood glucose measurements and the difference between corresponding pre-prandial and post-prandial blood glucose measurements.
3. The method according to claim 2 , wherein
the allocation to the time categories is based on the time of the pre-prandial blood glucose measurement.
4. The method according to claim 1 , wherein
determining the chronological sequence of the blood glucose measurements labeled pre-prandial is carried out in ascending order starting with the oldest pre-prandial blood glucose measurement.
5. The method according to claim 1 , wherein
the time selection criteria is a time frame from 60 minutes to 140 minutes starting after the respective labeled pre-prandial blood glucose measurement is used to identify the post-prandial blood glucose measurement.
6. The method according to claim 1 , wherein
if several post-prandial blood glucose measurements are present which fulfill the time selection criterion, the highest blood glucose measurement is used to pair with the corresponding pre-prandial blood glucose measurement.
7. The method according to claim 1 , wherein
steps ii) and iii) proceed in such a manner that
starting with the oldest pre-prandial blood glucose measurement firstly the highest corresponding post-prandial blood glucose measurement is determined;
storing this oldest blood glucose measurement pair for further processing;
determining subsequently the next oldest pre-prandial blood glucose measurement and the highest corresponding post-prandial blood glucose measurement;
storing this next oldest blood glucose measurement pair for further processing; and
repeating these steps until all blood glucose measurements have been taken into consideration up to the most recent pre-prandial blood glucose measurement and, optionally, the highest corresponding post-prandial blood glucose measurement.
8. A system for determining the difference between pre-prandial and post-prandial blood glucose measurements, comprising:
a blood glucose measuring instrument,
a data processing device, and
a computer program having instructions that when executed carry out the following a method for determining the difference between pre-prandial and post-prandial blood glucose measurements,
i) reading out blood glucose measurements provided with a relative or absolute time mark and labeled as pre-prandial and reading out other blood glucose measurements provided with a relative or absolute time mark from the memory of a blood glucose measuring instrument;
ii) determining the chronological sequence of the blood glucose measurements labeled as pre-prandial;
iii) determining the post-prandial blood glucose measurement from the other blood glucose measurements that pairs with each of the labeled pre-prandial blood glucose measurements by applying a time selection criterion;
iv) determining difference values between corresponding pairs of pre-prandial and post-prandial blood glucose measurements; and
v) displaying the difference values.
9. A non-transitory computer program product for determining the difference between pre-prandial and post-prandial blood glucose measurements, comprising:
a non-transitory computer program having instructions that when executed carry out a method for determining the difference between pre-prandial and post-prandial blood glucose measurements,
i) reading out blood glucose measurements provided with a relative or absolute time mark and labeled as pre-prandial and reading out other blood glucose measurements provided with a relative or absolute time mark from the memory of a blood glucose measuring instrument;
ii) determining the chronological sequence of the blood glucose measurements labeled as pre-prandial;
iii) determining the post-prandial blood glucose measurement from the other blood glucose measurements that pairs with each of the labeled pre-prandial blood glucose measurements by applying a time selection criterion;
iv) determining difference values between corresponding pairs of pre-prandial and post-prandial blood glucose measurements; and
v) displaying the difference values.
