Phlebotomy Quizzes - Free Printable

It looks like you've uploaded an image showing six test tubes, each with a different colored cap: yellow, light blue, red, green, purple, and gray. Below the tubes, it says "PHLEBOTOMY TEST."

This is a common visual puzzle often used in medical or phlebotomy-related contexts to test knowledge of blood collection tubes and their corresponding additives.

Let’s break down what each color typically represents in phlebotomy:

1. Yellow Cap – Typically contains ACD (Acid Citrate Dextrose). Used for blood banking, such as blood typing and crossmatching.
2. Light Blue Cap – Contains Sodium Citrate. Used for coagulation studies (e.g., PT/INR, aPTT).
3. Red Cap – Usually plain tube (no additive) or serum separator tube (SST). Used for serum chemistry tests (like glucose, electrolytes, liver function).
4. Green Cap – Contains heparin (usually lithium heparin). Used for plasma chemistry (e.g., electrolytes, ammonia).
5. Purple Cap – Contains EDTA. Used for hematology tests (e.g., CBC, differential).
6. Gray Cap – Contains fluoride and oxalate. Used for glucose testing (prevents glycolysis).

So, if this is a puzzle asking you to identify the correct order or purpose of these tubes, the answer would be based on standard phlebotomy practices.

Possible Interpretation:

If the question is simply asking what this image represents, then the answer is:

> This image shows the standard colored-capped blood collection tubes used in phlebotomy, each containing different additives for specific laboratory tests.

Common Phlebotomy Tube Order (when drawing blood):

The recommended order of draw is:
1. Blood culture (yellow)
2. Coagulation (light blue)
3. Serum (red or SST)
4. Heparin (green)
5. EDTA (purple)
6. Glycolytic inhibitors (gray)

This sequence helps prevent cross-contamination of additives.

✔ So, the image likely illustrates the correct order of blood collection tubes used in a phlebotomy test.

Final Answer:

The image depicts the standard set of blood collection tubes used in phlebotomy, each with a colored cap indicating its additive and purpose:
- Yellow: ACD (blood banking)
- Light Blue: Sodium Citrate (coagulation)
- Red: Serum (chemistry)
- Green: Heparin (plasma chemistry)
- Purple: EDTA (hematology)
- Gray: Fluoride/Oxalate (glucose)

This setup is essential for accurate lab testing and proper specimen handling.
