Abstract
The present disclosure provides a quality control substance for use in the analysis of leukocytes, which can be prepared safely with easily available raw materials, which has excellent preservation stability, and which can be used in the analysis of sediments in a sample. This quality control substance includes artificial particles whose form as observed with a microscope is similar to the form of leukocytes as observed therewith.
Claims16
A method for analyzing a sample using a urine sediment analyzer, comprising the steps of:
- controlling the measurement accuracy of the urine sediment analyzer with artificial particles whose form as observed with a microscope is similar to the form of leukocytes as observed therewith, for measuring a concentration of leukocytes in the sample;
- and
- analyzing the sample with the urine sediment analyzer.
A method for controlling a measurement accuracy of an analyzer that measures a concentration of particles whose form is similar to the form of leukocytes in a sample, by counting the number of the particles in the sample, the method comprising the steps of:
- measuring a concentration of particles in a quality control substance comprising artificial particles whose form is similar to the form of leukocytes, using the analyzer, to obtain a measured value;
- and
- determining the measurement accuracy of the analyzer by comparing the measured value with a reference value.
