Was this a fair test? is it representative of the effectiveness of the test substance

1 answer:

8 0

<span>No. The test is not a fair test. The test is artificial. Testing the disinfectant against bacteria in a test tube is not representative of the effectiveness of the disinfectant against microbes in the environment. Test tube tests test for efficacy. Effectiveness can only be tested out in the environment.</span>
