Is There a Difference Between a Test Tube and a JLL Column?

Is there variation between results that you might expect and a test tob verses, verses the column? You know, so at first, when we first started to use jall, actually, ecause i've been doing this for a while a i thought ol jall was going to be more sensitive. And in actual fact, it isn't more sensitive. A, especially again, when you're in a reference labe setting. It's very similar reactivity to the test tubs. We always run a jall column, an dat negative humulitic anemia valuations. E, i really thought it would be more sensitive, but i don't think.
