That is to say, if the content of the analyte in the specimen is within the linear range, the measured results are credible, but outside this range, the results will be inaccurate. For example, a certain ALTY reagent The linear range is 0-400U/ML. If the patient's true value is 200, then the measured result is also 200, then this result is accurate. However, the patient's ALT content is 2000, which exceeds its linear range, and the measured result is If it does not come out, it may be a negative number, or it may only be 1 or 2. At this time, the sample must be diluted and measured again.
