Who we are
We are a vertically integrated company with R&D, manufacturing and commercial sales.We are a national hi-tech enterprise and CE certified. We have bulit ourself-owned core technologies with Ingenuity,and realized mass production of QDs diagnostic reagents with an annual output of over 2 million aliquots for the first time nationwide upgrading and promoting QDs tech.,we improved the precision of the chromatographic methodology to within 10% for the first time,making it the first IVD company to achieve the "pg" detection level using the chromatographic method in our country.
In the future, we will advance with time and continue to focus on the R&D of QDs technologies.

New concept of Whole-process quality control
1.concept description
Quality Control is a general concept that can be applied in any field. For clinical laboratory medicine,Quality Control is the guarantee and premise to obtain true value,and to evaluate the precision, accuracy and stability of the whole test system.
2. why clinical medicine requires quality control:
(1)The traceability and precision of the test system.
(2)Accuracy of measurement results.
(3)Comparable results.
I. Raw Materials: our Beidou QDs system (arranged in four rows)
Description:
1.QDs Fluorescence diagram and Absorption spectrogram:
(1)FWHM:It is normally between 35nm and 38nm, and is less than 40nm. We can achieve 34nm with exclusive technology.
(2)Absorption peak:The fact that the first exciton peak of Absorption spectrogram(blue) be sharp will indicate a great uniformity of QDs.
2. Transmission electron microscopy:QDs have a great uniformity.
3. Our QDs:highly-productive raw material (5g QDs for 20 million reagent cards). The productivity and inter-batch variation of raw material are of great significance to the inter-batch variation and stability of reagents.
II.Production Quality Control:With the whole-process barcode inspection, poor-quality reagent strip/test card can be automatically identified and eliminated.The automatic equipment in replacement of manual full inspection can increase the accuracy and qualified rate of detection. All the manufacture process will conduct in accordance with the standards of ISO 13485 Medical devices -- Quality management systems -- Requirements for regulatory purposes.
III. Quality Control for analyzers :The patented Eu2+ & Mn2+ element quality control card employ absolute quantification method to assign values, which keeps the analyzer CV<1%.
Iv. Quality control of reagent R&D: self-developed freeze-dried powder quality controls (Levey-Jennings quality control)

Levey-Jennings control chart
Description:
1.31 quality control test results are plotted in the chart. The quality control chart Have warning limit set as X+2SD and control limit set as X+3SD.
2.Levey-Jennings is the most commonly used control chart in laboratory . In general, the laboratory inspects the quality of the detection results by measuring the controls, and plots the quality control results on control chart. According to the control rules, the laboratory decides whether the detection is “in-control” or “out-of-control”.
3.We have the quality control conditions and strictly implement the international general quality control standards.
V. In clinical application: reading SD card for system calibration; the Control line used to eliminate abnormal reactions.
Description:
T line : Test line C line : Control line. In clinical application, the fluorescence intensity on Test line is directly proportional to sample concentration, so as to achieve quantitative detection. When the analyzers recognize the absence of Control line, the analyzers will classify the result to be invalid and do not calculate the measurement data, so as to eliminate abnormal reactions and ensure the accuracy of clinical test results.
