this is because the enzyme may not react as quickly at lower temperatures in the case of a lateral flow test strip where a meter is used to read the strip and calculate a level of analyte in the sample the meter may include a light source and a sensor the sensor detects the reflectivity color change fluorescence or other feature of the stripe this detected level is converted via an algorithm in the meter to a level of analyte in the sample in some configurations the algorithm may be stored on an insertable chip or similar item therefore particular test strips may be provided with particular chips including algorithms for the test strips therefore in some embodiments the algorithm for calculating concentration of an analyte from the color change may be modified in relation to the temperature detected by the meter to accommodate this change the meter may include a temperature sensor to detect ambient temperature and provide the proper calibration to the meter in many embodiments enzymatic activity doubles about every 10 u00b0 c that means that under typical ambient conditions there can be twice the amount of color produced during an end product measurement by the exact same amount of enzyme and thus can be reported relative between 1 u00d7 and 2 u00d7 the actual amount typical ambient conditions may range from 15 u00b0 c to 30 u00b0 c most analytical systems have temperature controls that heat the entire system to 37 u00b0 c body temperature to avoid issues with temperature however in the context of a lateral flow.
