What is the difference between a qualitative and semi quantitative test

In microbiology different tests are performed like Microbial limit tests (MLT), Sterility, Bacterial endotoxin testing (BET) and LBPC etc. In these tests some are qualitative, some are quantitative and some are semi quantitative tests.

Qualitative tests: Qualitative tests are those tests in which results are only given in form or either pass or fail or present or absent. In these type of tests results are not given in form of counting or calculations. Sterility test is one of example of qualitative test because in sterility test, results would be either pass or fail. In sterility testing we could check either contamination is present or absent in the sample.
