IDNOW and only influenza A reported

Not that flu season is upon us, we are starting to see some positive flu A. Per the user manual, results for the flu testing should be Flu A positive/Flu B negative or Flu A neg/Flu B pos, etc. The point being that there should be a result for both A and B if the procedural control is valid. A result of Flu A: Positive/Flu B:Invalid is also noted in the manual.
We are getting occasional results of Flu A: Positive and no result for Flu B. Procedural control is valid. Per Tech Support, the result is due to operator error. Anyone experiencing this?

Hi! Check your settings for the ID NOW device. There is a mode for FLU A/B that is called "Early Detection" mode. This mode will stop processing once one of the two results comes back positive. You'll get the results as soon as one analyte comes up positive and no result for the second analyte.
Yup, meant to put that in the post, Early Detection mode is OFF.
hello, this happens when operators stop the test when either Flu A or Flu B is detected, and they do not let the test to continue until the end. Operators error.
We have also seen this happen with Early Detection "Off" and the operators are not stopping the test early. We haven't gotten a good response from tech support either.
We have several ID Now analyzers and have not seen this. If early detection is off and the onboard instructions are followed you can run the test again (same as repeating an invalid result). If the problem persist, I would power off the unit and reset to factory setting, run controls followed by a patient swab. If the issue isn’t resolved, I would ask tech support to replace it.
