Our lab never bothered about the "new fangled stuff".
 My age determines that, I suppose ....
We still use EDTA rabbit plasma slide coagulase.
 If colony morphology doesn't fit thr result we confirm with tube coagulase.
Same plasma, diluted in broth. 
I would like to use DNAse routinely as well, but there are people even older than me!
