In the past, I've had some troubles getting a big enough drop. With my InRatio, you have to not only get that good sized drop, you have to put it on a small dot on the strip. With the XS, being able to just touch the drop to the side of the strip sounds like it's a bit easier.
Usually, I follow the suggestions made at the InRatio site -- run some warm water on your hand before testing. This seems to help the capillaries fill up with blood. I use a 21 gauge lancet (I recently got a lifetime supply of these lancets, so may wind up selling extra lancets and lancing devices), set for maximum depth. Don't be afraid to apply some pressure to the lancing device -- it helps to get a deep enough incision. I use the second or third finger on my left hand and usually incise (or lance) slightly below the nail, and a bit away from the side of the finger. If I need more blood, I try not to 'pump' it from lower down on the finger - InRatio recommends just pushing down on the fingertip just above the knuckle -- it prevents blood from flowing back down the finger, and helps to get more blood out through your incision.
I also sometimes put pressure on my fingertip, just above the knuckle, before lancing the fingertip. This seems to help get more blood into the fingertip.
I've also just recently tried some capillary tubes I got months ago. These suck the blood into the small plastic capillary device. A line shows when there's enough blood. From there, it's just a matter of squeezing the end of the tube and depositing the blood onto the strip. So far, this seems to work well for me - and I know even before putting the blood on the strip whether or not there's enough. Knowing this can help prevent wasting strips because of inadequate blood.
One thing you should know -- the strips are designed to take a drop of blood within fifteen seconds of lancing your finger. Beyond that, your blood may start to coagulate and your reading won't be accurate.
(BTW: Those capillary tubes are available from a lot of suppliers - and may also be available from Roche. I got mine for maybe 10 or 15 cents each on eBay. They seem to work just fine for me.)
Oh -- and congratulations on getting the meter. If you're like me, you'll feel empowered when you use it, knowing that you're more in control of your testing and will rarely have to visit a lab for a blood draw.
