### Control Intervals
The longer the intervals between tests, the more research has to be put into questions and has to be repeated in case of contamination.
The longer the intervals between tests, the more research work will be put under question and will need to be repeated in case of contamination.
The LCSB, therefore, recommends testing cell cultures for mycoplasma contaminations **at time of arrival** and afterwards at **monthly intervals**.
You do not only prevent your own research results to be invalidated, but help your colleagues' cell cultures to remain free of mycoplasma contaminations.
