A typical example is 28G1/2. The "28" is the gauge of the needle--the measure of its diameter. The fraction after the "G" is the length of the needle (just be as consistent as possible) measure in inches. So 28G1/2 is a 28 gauge needle which is a half inch in length.

The 25-gauge needle has been available for only six months in Canada, and is being used by only a few centres in the country. The 25-gauge needle has a diameter of 0.5mm, almost half the size of the 20-gauge needle.

"The 11 gauge is more accurate than the 14," said Roger Jackman, MD, lead author of the study. "Specimens obtained with both needles are the same length, but those with the 11-gauge needle are larger in diameter and volume which presumably leads to the better results with the 11-gauge needle.
