Intended use
This device is intended to be used for the in vitro quantitative determination of C-peptide in human whole blood, serum or plasma. And it is for professional use only, not for self-testing of untrained individuals, nor for near-patient testing.
Summary
Human C-peptide is a single chain polypeptide consisting of 31 amino acids. It connects the A and B chains of insulin in the precursor molecule proinsulin, which is stored in secretory granules of the pancreatic β-cells. 1,2,3 In insulin biosynthesis, it facilitates the formation of the correct secondary and tertiary structure of the hormone. 3,4 C-peptide and insulin are secreted in equimolar amounts, however, C-peptide does not undergo significant hepatic extraction but is renally eliminated and therefore persists longer in the peripheral circulation. This results in a longer half-life (> 30 minutes) and less fluctuation of C-peptide compared to insulin (5 minutes). 4,5 Hence, measurements of C-peptide more accurately reflect pancreatic insulin secretion rates than insulin. Moreover, C-peptide concentration is independent of exogenous insulin and is not subject to interference from insulin autoantibodies induced by insulin therapy.
The current clinical methods for detecting C-peptide include chemiluminescence, immunochromatography and so on.

FAQ
Q: Can reagents from different batches be mixed?
A: No.
Q: Are the results of CRP, SAA whole blood and peripheral blood the same?
A: Our laboratory big data test results show that the test results of CRPSAA on whole blood and fingertip blood are consistent. In the process of detecting fingertip blood, the inspecting doctor should try to avoid inhaling impurities such as subcutaneous tissue, which may lead to deviations in the test results.
This question is placed under the two products of CRP and SAA.
Q: Is it possible to add emergency testing to our instrument in the middle of the testing process?
A: LYOFIA 100, DISKFLU 1000, these two instruments can achieve.
This question is placed under LYOFIA 100, DISKFLU 1000, these two products.
