Abstract: FIELD: measuring. 
     SUBSTANCE: invention relates to metrology. The method for building systems for measuring physical quantities with multi-circuit feedback includes building a measuring system on one sensor or on one sensor channel, if that is a multi-channel source information channel with several feedback circuits, wherein each is designed for its own frequency range. If present, the measured effect is divided into frequency ranges, wherein the effect is compensated by one of the closed circuits, thereby significantly reducing the influence thereof on the remaining closed circuits, including the main measuring circuit. To receive additional information on the measured quantity, a possibility of outputting the output signal from the remaining closed circuits is present. The information on the value of high-frequency effects can be used to correct errors in the measuring unit, since the effect acting directly on the sensing element is measured. If a first order astatism is present in the main measuring circuit, the value of the signal measured by subsequent circuits in the own frequency ranges thereof will be directly proportional to the first derivative for the value measured by the main closed circuit. This information will also allow for further implementation of fundamentally new signal processing algorithms directly in the measuring system. 
     EFFECT: increase in the accuracy of the main measurement channel.

At admission to hospital in patients with CKD with suspected community-acquired pneumonia, concentrations of procalcitonin and β2-microglobulin in blood serum are determined. Ratio of these two proteins is found by dividing the concentration of procalcitonin by the concentration β2-microglobulin, multiplied by 100. If the coefficient is less than 5 points, pneumonia of non-bacterial etiology is diagnosed. If the values are from 5 to 10 points, moderate bacterial pneumonia is diagnosed. Above 10 points, severe bacterial pneumonia is diagnosed.
