The invention discloses a cigarette test bench error correction method and device, a medium and a program product, and relates to the technical field of measurement error correction. The cigarette test bench error correction method comprises the following steps: acquiring a repeatability index, a system bias value and a measurement error distribution characteristic of a current error to-be-compensated test bench; determining a stability index according to the measurement stability analysis experiment data, and determining a reproducibility index according to the filter stick measurement reproducibility experiment data; according to the repeatability index, the system bias value, the measurement error distribution characteristic, the stability index and the reproducibility index, determining key factors of performance degradation of the test board; and compensating the current measured value of the current error to-be-compensated testboard based on the testboard performance degradation key factors and the error compensation model. According to the technical scheme of the embodiment of the invention, the auditing standards of new and old cigarette test benches can be unified, and the error correction effect of the cigarette test bench can be effectively improved.

To provide reagents and measurement methods that exhibit excellent measurement reproducibility. [Solution] A reagent for measuring a target substance contained in a sample, wherein the target substance is ferritin, and the reagent comprises a first reagent containing a buffer and a second reagent containing particles on which a ligand that specifically binds to the target substance is immobilized, wherein a first mixing step is performed to obtain a first mixed solution by mixing a sample containing 1000 ng / mL of the target substance with the first reagent in a volume ratio of sample:first reagent = 15:60, and a second mixing step is performed 280 seconds or more after mixing in the first mixing step to obtain a second mixed solution by mixing the first mixed solution and the second reagent in a volume ratio of first mixed solution:second reagent = 75:30, wherein the absorbance change of the second mixed solution becomes 0.15 or more within 50 seconds after mixing in the second mixing step.
