The Ames test is one of the oldest, most common tests for mutagens. It uses a strain of S. typhimurium that contains a mutation which prevents the synthesis of histidine, an essential amino acid.
The test measures the rate of reversion mutation; ie., the bacteria must regain the the ability to synthesize histidine to grow. Chemicals which increase the rate of mutation increase the number of colonies which grow on minimal media. Here we will be testing the ability of several substances to cause reversions.
The use and advantages of the Ames test is based on the assumption that any substance that is mutagenic may also turn out to be a carcinogen, that is, to cause cancer. Although, in fact, some substances that cause cancer in laboratory animals do not give a positive Ames test (and vice-versa), the ease and low cost of the test make it invaluable for screening substances in our environment for possible carcinogenicity.
All microbio lab books says is that not all mutagens used are carcinogens. Time can also play a role, you have to run a whole lot of tests

The Ames test identifies chemical mutagens.

The substances that are test positive with Ames test may or may not be carcinogenic for humans. Similarly, some substances that cause cancer in laboratory animals do not give a positive result Ames test. It is not possible to decide the carcinogenicity of any substances only depending on the Ames test.
Ames test would typically be carried out in the field of biology, more specifically toxicology. The Ames test involves testing genetics, which involves taking a sample and examining it closely in a laboratory.
The Ames Test
The Ames test is a quick method that uses bacteria to assay for cancer causing chemicals. A false positive is possible when a nitrogen based material is used.
what is the advantages of weekly test
Ames test is used to test whether a certain substance is mutagenic. Liver extract is optionally added to simulate the effect of metabolism, as some compounds, like benzo[a]pyrene, are not mutagenic themselves but their metabolic products are.
