The yellow top tube is used for PT (protime) testing as it contains sodium citrate, which prevents the blood from clotting. The lavender top tube is used for stat electrolyte testing as it contains an anticoagulant called EDTA. The green top tube is used for blood culture (BC) as it contains heparin, which inhibits clotting and allows for growth of microorganisms.
