Question

Know the Order of Draw from your handout (note: NOT FROM BOOK, which does not cover as many tubes as your handout)?

Answer 1

The Order of Draw is a specific sequence in which blood collection tubes should be filled during venipuncture to avoid cross-contamination and maintain accurate test results. The correct order is: Blood culture, Coagulation, Serum, Heparin, EDTA, Glycolytic inhibitor, Fluoride tubes.

Step-by-step explanation:

The Order of Draw is a specific sequence in which blood collection tubes should be filled during venipuncture to avoid cross-contamination and maintain accurate test results. The correct order of draw is as follows:

1. Blood culture tubes - used to detect bacteria or yeast in the bloodstream.
2. Coagulation tubes - used for tests that assess blood clotting ability.
3. Serum tubes - used for various tests that require serum samples.
4. Heparin tubes - used for tests that require plasma or whole blood samples.
5. EDTA (Ethylenediaminetetraacetic acid) tubes - used for tests that require whole blood samples, especially for CBC (Complete Blood Count).
6. Glycolytic inhibitor tubes - used for tests that require glucose measurement.
7. Fluoride tubes - used for tests that require glucose or alcohol measurement.

By following the correct order of draw, the risk of test result contamination and inaccurate results is minimized.
