Final answer:
The proper order of collection for PT (protime), stat electrolytes, and blood culture (BC) is yellow top, lavender top, green top.
Step-by-step explanation:
The proper order of collection for PT (protime), stat electrolytes, and blood culture (BC) would be:
- Yellow top
- Lavender top
- Green to
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.
