Accurately testing junctions/symlinks validity

I need to test symlinks (junctions) created in WSL (via ln), because they may not always be valid.

The simplest test I could find is to verify the output of:

(Get-Item %FILENAME%).Target

which is blank if the junction is invalid.

However, there's an edge case where this test returns a false negative, that is, when a file junction points to a directory.

Is there some (very simple) command I can run to perform a test that covers also this case?

The test needs to be able to be executed from a Bash script inside WSL (to be specific, the command above is run via [[ -z $(powershell.exe -Command "(Get-Item %FILENAME%).Target")).
