Yes 1:40 is the lowest titer. That's one single dilution. The titer
doubles with each dilution (1:80, 1:160, 1:320, etc) that's how those
numbers can really get up there.
The fluorescence is used to observe the cells under the microscope....
depending on how the cells look, mean different things.... mine are always
speckled.

I think if if it says <1:40... that means there were ANA cells, but upon
dilution, no more... so they were there, but after dilution (the first
dilution) no more.

I too think Quest Lab leaves a lot to be desired.
