with or without having symptoms的分析与理解

We use current COVID-19 infections to mean testing positive for SARS-CoV-2, with or without having symptoms.

老师们,这里的with or without having symptoms感觉很别扭,好像它是一个独立的存在,请老师帮我解析一下这个短语的作用

with or without having symptoms这个介词短语为动名词短语 testing positive for SARS-CoV-2 的伴随状语。整个testing positive for SARS-CoV-2, with or without having symptoms 为动名词短语,作to mean的宾语。 to mean testing positive for SARS-CoV-2, with or without having symptoms.这个不定式短语为目的状语。
