Expert writing Tips

Best practice

Avoid using the phrase "tested about" in formal writing. Instead, opt for more precise alternatives such as "tested for", "tested regarding", or "evaluated for" to ensure clarity and grammatical correctness.

A common mistake is to use "about" after "tested", which is grammatically incorrect. Always consider what you are testing for or regarding to choose the correct preposition. For example, say "tested for lead" instead of "tested about lead".
