Urine Analyzer Calibration Specifications
1 Scope
This specification applies to the calibration of various types of urine analyzers.
2 Overview
The urine analyzer (hereinafter referred to as the instrument) is based on the measured components in the urine and the corresponding test blocks on the urine test strip.
Independent reactions produce color changes for qualitative and quantitative measurement of urine composition. Test strip color block color change
The depth is proportional to the corresponding components in the urine, so that the relative density (SG), pH, and whiteness of the urine are achieved.
Cell (WBC or LEU), nitrite (NIT), protein (PRO), glucose (GLU), ketone body (KET),
Urobilinogen (URO or UBG), bilirubin (BIL), red blood cells (RBC or BLD), and vitamin C (VC)
Detection of the component.
The instrument is mainly composed of photoelectric scanning system, mechanical system, motherboard, display system and attached test strips.
3 Metrological performance requirements
3.1 blank
Should meet the requirements of Table 1.
Table 1 Technical requirements for instrument blank
Parameter SG pH
/( /μl)
/( /μl)
0 0 0 0 0 ≤3.4 0 0 0
Note. 1. The measurement results of the instrument (except SG, pH and VC) have two other representation methods, namely “-” and
"neg", both of which are negative; or "normal", indicating normal. See Appendix A.
2. According to the instructions, individual instruments GLU ≤ 0.6mmol/l.
3.2 indication
The measured values of the instrument shall comply wit
