TVC swab test
TVC/Aerobic Colony Count gives a general measure of bacterial activity in a water system.
When to use it
A TVC (Total Viable Count), also known as an Aerobic Colony Count, gives a general measure of bacterial activity in a water system. It’s used where water hygiene is a concern, for example in systems affected by flooding or prolonged stagnation, or as part of a wider investigation.
How sampling works
A swab or water sample is taken from the system or surface being tested and incubated in our laboratory, allowing any bacteria present to grow to a countable level.
What’s in the report
The result is reported as a colony count. Interpretation is usually made alongside the wider condition of the water system rather than against a single fixed number.
