Caffeine test strips

If you're concerned about caffeine in your diet, help may be on the way in the form of a dipstick-style caffeine test strip. Chemists at Washington University School of Medicine in St. Louis say that the product would be the first of its kind, according to a story on FoodNavigator. The test strips would be treated with an antibody, cloned from one found in llama blood, that changes color when it comes in contact with caffeine. The strips wouldn't tell how much caffeine a drink had, only whether or not it was present. The llama blood antibody was apparently chosen because it worked well at high temperatures.

I am curious to see what a Llama with too much caffeine looks like though.
