You can only speak anecdotally.
Correct...but my experience, and that of my coworkers and friends at other locations is all the same, and matches with the state and national numbers. Also we are not talking about a few tests. We are talking many thousands, so I think we can read something into what I have seen.
Last winter I personally only saw 2 positive flu tests. The last 10 years, probably saw many hundreds of positive flu tests every winter. Every tech I work with saw the same, and every hospital in our huge system saw the same. I have friends in other cities in other hospital systems that saw the same. We all had positive results last year until last fall/winter. Then basically nothing all winter. Then late spring the positives returned. I think this tells us the flu was gone all winter. A bit more than anecdotal IMO.
