How to use microbial susceptibility analyzer

Microbial susceptibility analyzers, also known as bioanalyzers or biosensors, can be used to detect and analyze microorganisms such as bacteria, fungi, and yeast. The following are general steps for using a microbial susceptibility analyzer:

1. Prepare reagents and samples: Follow the instructions for reagents and samples. It is usually necessary to prepare standard strains, samples to be tested, culture media, buffers, etc.

2. Instrument calibration: Before using a microbial susceptibility analyzer, calibration is usually required. Perform calibration operations according to the instrument instructions.

3. Inoculate the sample: Inoculate the sample to be tested onto the test plate of the microbial susceptibility analyzer. Test plates typically consist of a series of microwells, each containing a different antibiotic or test substance.

4. Culture and analysis: Place the test plate into the microbial susceptibility analyzer for culture and analysis. The instrument detects the number and growth of microorganisms in the microwells through biosensors, and transmits the data to a computer for processing and analysis.

5. Interpretation of results: Based on the results provided by the microbial susceptibility analyzer, the sensitivity of microorganisms to different antibiotics or test substances can be determined, thereby providing clinicians with antibiotic treatment recommendations.

It should be noted that different microbial susceptibility analyzers may have different operating methods and instructions for use. The instructions for use should be read carefully and followed before use. At the same time, some complex samples may require special handling and preparation. If you encounter problems, you should contact the equipment supplier or professional technicians for technical support in time.
