Reconciling the singular and plural in a title

Here is the tile of a journal article: https://annals.org/aim/article-abstract/2724039/recognizing-potential-overdiagnosis-high-sensitivity-cardiac-troponin-assays-example

“Recognizing the Potential for Overdiagnosis: Are High-Sensitivity Cardiac Troponin Assays an Example?”

Hmm. I think it should be:

“Recognizing the Potential for Overdiagnosis: Is a High-Sensitivity Cardiac Troponin Assay an Example?”

The issue, of course, concerns the implications of a high-sensitivity assay.

Thanks.
