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 the impact of potential errors that may occur when a device receives a first code comprising a plurality of bits arranged in a physical arrangement and being associated with a diagnostic test strip, the method comprising:
determining a probability of each bit to cause a read error; and
constructing a logical arrangement of the bits different than the physical arrangement based on the probability, wherein the logical arrangement comprises the bits arranged such that the impact of potential read errors is minimized.
2. The method according to claim 1 , wherein the logical arrangement comprises the bits arranged such that the bit having the highest probability of causing a read error is logically replaced by the bit having the 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 the logically arranged code and determining the constituent level of the 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 bits are arranged to keep the code in sequence.
7. The method according to claim 6 , wherein the device reads the test strip as having the logical code arrangement in a sequential arrangement.
8. The method according to claim 6 , wherein the result of using the 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.
9. The method according to claim 1 , wherein the logical arrangement is performed as a non-sequential arrangement such that the original bits remain in sequence, but the resulting code space is arranged logically, based on the logical replacements.
10. The method according to claim 9 , wherein the device reads the test strip as having the actual code, but correlate the actual code to the logical code space which is created from the logical arrangement in a non-sequential arrangement.
11. The method according to claim 9 , 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.
12. The method according to claim 1 , wherein the device reads the first code from the diagnostic test strip.
13. The method according to claim 1 , further comprising reading the first code associated with the diagnostic test strip.
