Here counting is based on viable colonies which can grow in a liquid medium contained in a series of 3 or 5 or even 10 tubes in different concentration. A tvc is achieved by plating serial tenfold dilutions of the sample until between 30 and 300 colonies can be counted on a single plate.

Presentation 5 Total count is a very general term that, in this context, requires a more specific definition.
Total viable count (tvc) is a test that estimates the total numbers of microorganisms, such as bacteria, yeast or mould species, that are present in a water sample. The aerobic plate count (apc) is also known as standard plate count, aerobic mesophilic count, total plate count or aerobic colony count. A sample to be counted is diluted in a solution that will not harm the microbe, yet does not support its growth (so they do not grow during the analysis). The significance of the microbiological tests that may be conducted is discussed below.
