Answer :
Final answer:
The tubes used for capillary blood collection in the order of WBC, RBC, and electrolytes are 3) Green top tube, 1) Red top tube, 4) Blue top tube
Explanation:
- Firstly, the green top tube is utilized for the collection of capillary blood samples for electrolyte analysis.
This tube contains an anticoagulant such as heparin, which prevents blood clotting and preserves the sample for electrolyte testing. - Secondly, the red top tube may be used for capillary blood collection to analyze parameters related to red blood cells, such as hematocrit or hemoglobin levels.
- Lastly, the blue top tube, typically used for coagulation studies, is not commonly employed for capillary blood collection and is not typically used for the assessment of WBC, RBC, or electrolytes, hence the correct answer is 3) Green top tube, 1) Red top tube, 4) Blue top tube
