Why do you need different toothpicks to mix the blood and serum on slide 1 and 2?

I don't know what experiment you're conducting, but when the directions tell you explicitly that you need to use a fresh utensil, then there must be the potential for contamination. Most likely using a different toothpick prevents the contents of slide one from crossing to slide two, which could invalidate your results.
