Abstract
A concentration determination method includes the following steps. A sample fluid having a target material therein is diluted with a 1dilution factor to an Ndilution factor to form a 1sample to an Nsample. A bio-sensing integrated circuit having a 1assay to an Nassay is provided. The 1sample to the Nsample are respectively applied to the 1assay to the Nassay. A bio-sensing process is performed on the 1sample to the Nsample to obtain a 1measurement value to an Nmeasurement value. The 1measurement value to the Nmeasurement value are compared with a threshold value to determine a threshold dilution factor, which corresponds to a largest dilution factor that has a measurement value higher than the threshold value. A concentration of the target material is calculated based on the threshold dilution factor and a limit of detection.
