The kit has four little circle things that you have to put blood on. The first two circles determine if you are A, B, or O. If your blood clumps in the first circle, you are A. If it clumps in the second circle, you are B. And if it doesn't clump at all, you are O. The third circle determines if you are positive or negative. If it clumps in the third you are positive, and if it doesn't clump, you are negative. The last circle is a control that doesn't do anything. Crystal had to explain it to me because I didn't know how to determine it =)
