Error detection and rejection for a diagnostic testing system
A system for measuring a property of a sample is provided. The system comprises a diagnostic measuring device having a memory and a diagnostic test strip for collecting the sample. The strip has embedded thereon a pattern representative of at least first data and second data, the first data being data representing at least one of parameters related to measuring the property, codes usable for calibration of the diagnostic measuring device, or parameters indicating proper connection between the measuring device and the test strip and the second data usable for detecting and rejecting potential errors affecting the proper measurement of the property.
1. A method for minimizing an impact of potential errors that may occur when a device receives a code, the method comprising:
reading a first code comprising a plurality of bits arranged in a physical arrangement;
determining a probability of one or more bits of the plurality of bits to cause a read error; and
constructing a logical arrangement of the one or more bits different than the physical arrangement based on the probability, wherein the logical arrangement comprises the one or more bits arranged such that an impact of potential read errors is minimized,
wherein the first code represents at least one of parameters related to performing a diagnostic test by the device.
2. The method according to claim 1 , wherein the logical arrangement comprises the one or more bits arranged such that the bit having a highest probability of causing a read error is logically replaced by the bit having a lowest probability of causing a read error, and the bit having the lowest probability of causing a read error is logically replaced by the bit having the highest probability of causing a read error.
3. The method according to claim 2 , wherein the logical arrangement results in a second code which is read in sequence.
4. The method according to claim 2 , wherein the logical arrangement results in a second code which is not read in sequence.
5. The method according to claim 1 further comprising performing an error detection and rejection algorithm on logically arranged code according to the logical arrangement and determining a constituent level of a fluid if the error detection and rejection algorithm detects an acceptable error or does not detect an error in the logically arranged code.
6. The method according to claim 1 , wherein the logical arrangement is performed as a sequential arrangement such that the logical arrangement of the one or more bits are arranged to keep the code in sequence.
7. The method according to claim 1 , wherein the logical arrangement is performed as a non-sequential arrangement such that the first code remains in sequence, but a resulting code space is arranged logically, based on logical replacements.
8. The method according to claim 7 , wherein the device reads a test strip as having the first code, but correlate the first code to the resulting code space which is created from the logical arrangement in a non-sequential arrangement.
9. The method according to claim 7 , wherein the result of using the non-sequential arrangement creates a code space to be recognized by the device as having acceptable codes, such that a test strip having a code with least significant bit errors will be acceptable, and having a code with the most significant bit errors will not be acceptable to the device.
10. The method of according to claim 1 , wherein the first code is embedded on a diagnostic device.
11. The method according to claim 10 , wherein the diagnostic device is a diagnostic test strip.
