    In a pinch, that's what we go by. (such as if he is testing in the middle of a baseball field. Heck, he's only 6....there is a lot of idle time out there.)

    We never wipe away the first drop either.. As long as her hand is clean I don't see a need, and actually if you do wipe away that first drop you need to be careful there is nothing on whatever you wipe with that would contaminate it.

    We were not taught that nor did we see any of the nurses in the hospital do it that way.

    I had a rep from Abbot talk about wiping away the first drop when she was demonstrating the Quickwik butterfly strips to me. Seems kind of counterproductive to advertise your meter/strips as requiring the smallest blood sample on the market only to have to wipe it away and squeeze the finger again!

    Yeah it is kind of silly. And we were told in the hospital that we should never squeeze the finger to get more blood. We were told that could cause a false reading.

    I never knew this! (I thought you only got to interstial fluid if you didn't lance quite enough and really milked the fingert, instead of re-lancing.) Thanks.

    9 years, never wiped away the 1st drop, except if still wet from and alcohol pad. Use an alcohol pad about 80% of the time.

    There was a recent study that showed that using the second drop of blood brought better results if the hands were not washed first. Alcohol doesn't cut it. If you've washed hands with soap and water, there's no need for a second drop.

    We don't, normally, wipe away the first blood sample unless there is good reason to. If he has squeezed exceptionally hard, where interstitial fluid might be a concern, then we will. But otherwise no. In other words, maybe once in a VERY great while.

    We have found that washing with soap and water, if not completely dried, will dilute his bg levels, but it's kind of a "as warranted" basis. If he just washed his hands and we would expect him to be around 110 and he tests out at 45 then we just ensure that his hands are completely dry and do another test. KWIM? It just didn't make good sense.

    why is that?
    i didnt know that.
    I nearly smacked a well meaning ER nurse for doing that! My dd was severely dehydrated and one drop of blood was difficult to get...she wiped away a perfectly good drop, couldn't get any more and had to prick again....starting the whole process over until I stepped in. She said they were trained that way, and I've heard the interstitial fluid reason before...but we now know that cgms use interstitial fluid readings...so maybe the training needs to be updated.

    I was taught this at uni too. In fact, I almost failed a diabetes clinical skills exam for not doing so The lady who was examining me told me very gravely that it was extremely important. In real life, many of the patients who's BGs I check are old and don't bleed much. If I wiped away that precious first drop, I'd never get any blood! None of the nurses I work with practice this, and I certainly don't

    We were taught:

    1) if using an alcohol wipe or antibacterial gel to clean hands, wipe away first drop and test with second drop, or
    2) if washing with soap and water, just get finger nice and dry before testing on first drop.

    My understanding is that they want to ensure that the alcohol is fully wiped away before taking the sample. Since we stopped using wipes within a month of dx, it hasn't been an issue at all...
