PHLEBOTOMY PREP: YOUR CPT CERTIFICATION COMPANION
The order of draw can make or break your career. Learn it the right way with our interactive simulator.
ORDER OF DRAW SIMULATOR
Wrong order means contaminated specimens. Contaminated specimens mean wrong results. Wrong results mean patient harm.
Our drag-and-drop simulator teaches you the CLSI order:
1. Blood Culture (Yellow)
2. Coagulation (Light Blue)
3. Serum (Red/Gold)
4. Heparin (Green)
5. EDTA (Lavender)
6. Glycolytic Inhibitor (Gray)
Drag the tubes into the correct sequence. Tap verify. See if you got it right.
Correct order shows green success.
Incorrect order highlights your mistakes.
Practice until it becomes second nature. That is how you pass the exam and perform safely in the lab.
NEEDLE GAUGE SELECTOR
Bigger gauge number means smaller needle. It is counterintuitive. Our visual tool makes it clear.
Slide through gauges from 16G to 25G. Watch the needle graphic change size. See what each gauge is used for:
- 21G: Standard adult venipuncture
- 22G: Pediatric and elderly
- 23G: Butterfly for small veins
Never pick the wrong needle again.
VEIN SELECTION GUIDE
The antecubital fossa has three main veins. One is safest. One has risks.
Tap each vein on our interactive diagram:
Median Cubital: First choice. Largest, most stable, safest.
Cephalic: Second choice. May roll, but safe distance from nerves.
Basilic: Third choice. Caution required. Close to brachial artery and median nerve.
Learn why site selection matters before you ever touch a patient.
