Q:

Therefore, a person's test results may vary depending on the company that handles the results ... is it an attribute or an adverbial? I think there is no comma separation, it should be an attribute that can be translated. A person's test results will depend on the different feelings of the company that handles the results. If it is an adverbial, the translation depends on the company that handles the results, and the test results of the same person will be different. It feels smoother.

Answer: Obviously it is an adverbial, because different is a predicate verb, which is equivalent to different, depending on ..., similar to according to ..., equivalent to because ..., used as an adverbial. If it is a postattribute, it must be a noun or pronoun it modifies.
