Kahljorn, those syringes could have very small gague needles (diameter), wich thicker liquids may not be able to pass through easily. A even a single blood cell is almost too large to pass through a twenty guage (yellow cap) needle. I can't think of any other reason it would be so difficult.

I love sticking needles into people for some reason, especially when those people with really large veins come in, it feels like christmas.
