Yup, we had a lead test at 12months too. It can be done either as a finger stick or a regular needle draw at the elbow, like for adults. I would definitely recommend the finger stick, even though it takes a little while. If your baby is unhappy and struggling, there is no sharp object to content with that could potentially do them further harm as they wiggle.
We've had to do a couple of blood test for various reasons - sometimes it's a big deal, sometimes it's not.
