When testing for mastitis, be sure to specify whether you want mycoplasma included as well. 

Diagnostic labs don’t always include mycoplasma screening with their routine mastitis-testing procedures, points out Travis Thayer, technical services veterinarian at AgriLabs. Therefore, it is necessary to determine (1) if the lab is familiar with mycoplasma screening and, (2) if the lab is familiar, that it be included with your order.

If a farm has had clinical mycoplasma in the past, it ought to consider testing for mastitis every week, Thayer says. If it hasn’t had problems, it should still test every two weeks to a month, he says. “It’s important for any dairy to be in surveillance mode, because (mycoplasma) can just pop up,” he adds.
