Best practice
When using "is tested for", ensure the context clearly indicates the specific characteristic or substance being evaluated. For example, "The water is tested for contaminants" is more informative than "The water is tested".
Common error
While "is tested for" is grammatically sound, excessive use of passive voice can make writing seem indirect. Consider rephrasing to an active voice when possible, such as "Researchers test the sample for bacteria" instead of "The sample is tested for bacteria".
