A self-diagnosis method and apparatus for measuring results from blood analyzers, the method comprising: generating an acquisition transmittance curve according to the changes in transmittance rate of sample during a sample acquisition process; determining whether there is an anomaly in the acquisition process according to the acquisition transmittance rate curve; if there is no anomaly in the acquisition process, determining that the measurement results of the blood sample are credible; and if there is an anomaly in the acquisition process, determining that there is a doubt about the measured results of the blood samples, the self-diagnosis method and apparatus for measuring results from blood analyzer can improve the accuracy of self-diagnosis of measured results from blood analyzers, and reducing the false positive rate, at the same time, the workload of users in examining and verifying the measured results is reduced, thereby saving on measuring costs.

Self-diagnosis method and apparatus for measuring results from blood analyzers

A baseline processing device and method are provided for analyzing signals with uneven distributions of pulses and slow varying baselines. In one embodiment, the device includes an A/D sampling unit for sampling a digital counting signal to obtain sampled data, and a baseline extracting unit for sorting the N sampled data in the sampling sequence by magnitude and for outputting, among the N sample data, one sample data A with a value equal to the mid-value in the N sample data. A phase compensating unit with a width of M, to which a digital signal is input, outputs a sampled data B according to a FIFO sequence, wherein M=N/2. A first subtractor subtracts the sample data A from the sample data B and outputs the result as baseline removed data.
