1. Choose a test with identification value: To identify two bacteria, you must choose a test where the two bacteria show absolutely different results, that is, one bacteria shows positive (the positive rate of the positive reaction strain must be greater than 90%) , The other strain is negative (the positive rate of the negative reaction strain should be less than 10%), this test is only valuable for identification. Otherwise, there is no appraisal value.
2. Choose a simple, fast, and convenient test: â‘ There may be many specific methods for identifying a bacterium. There is no need to test one by one. It is only necessary to choose one or two of them to achieve the purpose. Multi-selection is meaningless. â‘¡Choose a simple and fast method. â‘¢Select the compound culture medium, and see several biochemical reactions at the same time, such as KIA, KIT, MIU, etc.
3. Comprehensively consider the sensitivity and specificity of the test: the higher the test sensitivity, the fewer false negative results. The higher the specificity, the fewer false positives. The sensitivity and specificity of the test are interrelated, and increasing the sensitivity of the test will decrease the specificity and vice versa.
As the name suggests, the Sit Stand Desk is a table that can be raised and lowered, so the lifting function is the biggest feature of this Height Adjustable Table. The lifting column is up and down through the control of the control box. Therefore, the most important part of an Electric Adjustable Desk is the lifting column (including the motor), the control box, and the hand controller. Without one of these three parts, the lifting function cannot be realized. The two lifting columns of the Dual Motor Standing Desk are controlled by two motors, and the stability and fluency of the dual-motors are more prominent among similar products.
