Are you swabbing for Pertusssis??

Had a woman bring her teenage son in the other day for coughing. Told me the Urgent Care told her to come to the ER to get a Pertussis swab as they were out. I must say I have never done a pertussis swab. They are send outs, no rapids. But it got me wondering, am I behind the times? I asked 2 of my partners and they said they didn't even know we could get the test. Anyone out there testing for this?
