Defective dairy H5N1 virus test

Apparently the CDC admitted last week to congress that the test that they first distrubuted to detect the dairy virus was defective.  They claim that it wasn't their fault, but that the company that they contracted to make the test screwed up on one of the H5 tests.  At this point they are still trying to get the company to rectify their error and create fully functional test kits.  It turns out that they have been working with the defective test for months.
It could be one of the reasons that they never started wide spread testing for the virus, though they do not make that claim.
The Scientific American article notes how something similar occurred at the start of Covid when the CDC produced a defective test that held up getting the virus under control.  This time the CDC claims that it wasn't their fault, but it likely is their fault that they didn't immediately get another company to make a functional test kit instead of waste months trying to get the contract company to fix their mistake. The article indicates that they are pretty sure that the company will make fully functional test kits soon.
