What is the nature of your test?
Did you clean your finger first?

Yeah it said to wipe it with antiseptic, leave it to dry then use the lancet to make a pin prick and "milk" 20 or so drops into the tube. I did everything they said, like take a shower beforehand & hold a cup of tea but it didn't work 
That's a shout...caz said:

If things aren't clean, particular chemicals can cause clotting.

Didn't know that... I've used 3 different fingers now and got it to like 500ul but it's so clotted that I doubt they're going to be able to use it. Oh well I'll just send it off and hope for the bestBillTre said:

Depending on the test, the clot can be spun down (in a centrifuge), yielding a supernant (the serum, a fluid) which might be usable for the test.

I don't know who "they" or "it" is, but I've never gotten more than a drop or two of blood from a lancet finger stick on my Pts. If you want 20 drops, you need to do a small gauge IV stick, IMO. I can fly over and take care of that if you want, but you'll have to pay for my flight and beers. Probably cheaper for you to go to your local health lab...ergospherical said:Yeah it said to wipe it with antiseptic, leave it to dry then use the lancet to make a pin prick and "milk" 20 or so drops into the tube.

That increases the yield to 2-3 drops. Don't ask me how I know this please...fresh_42 said:

It was not a "Report"able post, but I was unable to "stifle" myself (Archie Bunker, All in the Family, for those not native to "Yankee" culture) and DID "feed the troll."fresh_42 said:
