You have been getting enough liquid on the BinaxNOW test, I'm guessing? They say 6 drops, but honestly I've found 8 drops to be more accurate. They never send enough solution for me in the box of 40 tests I get!

I have all my kids self swab now for the pools - transitioned to this earlier this year after I could make sure all the kids did it properly. 

Yep, they've been all valid tests (same experience here, it's really 7-8 drops needed, and the solution always runs out before the kits!!)

Wow, I've never had the problem that six drops isn't enough.  Not surprised that you are running out of reagent early if you are using 30% more than recommended (and planned for by the manufacturer).

I often have to do 7-8 to get enough liquid into the small hole to read the swab. Several bottles I've had also don't drop well. I have actually submitted this issue to the manufacture and the CIC a few times.

Just a thought. The box of BinaxNOW that I opened recently. Seems to take a little bit longer for the fluid to travel up the testing window. It isn't the test card itself. It seems that the swabs have a little more cotton on it.  But, it still works. I don't want to sound condescending, so please please don't think that. But, if the manufacturer instructions say to use 6 drops. We should be doing that.

I don't think you sound condescending. But I have used 6 drops at first and more than a few times, the liquid has not traveled up at all and I've had to re-do tests because of it. 

This has happened to every nurse in my district as well. I guess it could just be us, of course. Different experiences for us all! But the extra drop has helped us avoid it. (The regent bottle we get in the single test kits has more than 6 drops in the single use bottle they provide.)

And of course you're supposed to use 8 drops for the control swab in each box. I wonder if the manufacturer has controlled for that...?

You are correct here and I totally spaced on that (since I only do one control per delivery batch and forget until I have to do another one)! They totally must.

Thank you. You have taught me something new. I only have used the kits of 30 tests per box. I didn't know that there is such a thing as a single test kit. (Can I go home now? I have already one thing new already today😉
