4. Lyophilized reagents do not require cold chain;
5. The analyzer has a simple structure, low cost and low failure rate;
6. No cleaning is required during the detection process
Biochemical Instrument Technology-Turbidimetry Advantages and Disadvantages
advantage:
1. Simple and fast,
2. The results are more accurate,
3. It has strong anti-interference ability and can be tested with general colorimeter, fully automatic or semi-automatic biochemical analyzer, and the instrument reagents are relatively cheap.
shortcoming:
1. The dosage of antibody is large, and it is necessary to ensure that the antibody in the reaction system is always in excess. However, an extreme excess can easily lead to the separation of immune complexes, seriously affecting the accuracy of the results;
2. If the immune complex molecules in the solution are too small, they will not be able to block the passage of light; if the number is too small, they will have little effect on the light flux; the sensitivity will be low;
3. Transmittance turbidimetry is in the second stage of the antigen-antibody reaction. The detection needs to be carried out after the antigen-antibody reaction reaches equilibrium, which takes a long time.
Biochemical Instrument Technology-Microfluidic Technology Advantages and Disadvantages
advantage:
1. High throughput and high efficiency,
2. Integrate miniaturization and automation
3. Small demand for testing reagents and samples
shortcoming:
1. Core technology lacks specifications and standards
