High-speed differential signals coupling capacitors

Just a curious question.

There are more and more high-speed lines on board today and most are AC-coupled differential lines with series capacitors on them. I notice some of the ICs support 1149.6 already which is the standard for this. I'm wondering if those capacitors are open and shorted, can they be detected and how?
