Site Picker PA
- Routine adult draw → Median cubital ( Least nerve risk )
- Median cubital unusable → Cephalic ( Anchor well, rolls )
- Both unavailable → Basilic last ( Nerve, artery nearby )
- Arm veins unusable → Dorsal hand ( 23G butterfly )

Hemolysis vs lipemia
- Hemolysis looks red ≠ Lipemia looks milky
Gauge vs bore

Standard vs transmission-based
- Standard applies always ≠ Transmission-based is added
Gold vs pink tube
- Gold for chemistry ≠ Pink for blood bank
Fasting vs basal state

Assault vs battery
- Assault is the threat ≠ Battery is the contact
Chill vs refrigerate
- Ammonia rides on ice ≠ Potassium never gets cold
Aerobic vs anaerobic first
- Butterfly: aerobic first ≠ Syringe: anaerobic first
Last Minute
