A blood collection tube with a LIGHT-BLUE top inhibits coagulation by:Group of answer choicesInhibiting enzyme systems involved in glycolysisForming complexes with calcium ionsConverts fibrin to fibrinogenAccelerating the action of anti-thrombin to thrombin
Solution
A blood collection tube with a LIGHT-BLUE top inhibits coagulation by forming complexes with calcium ions.
Here's a step-by-step explanation:
- The light-blue top tube contains sodium citrate as an anticoagulant.
- Sodium citrate works by binding to calcium ions in the blood.
- Calcium ions are necessary for the blood clotting process, specifically in the conversion of prothrombin to thrombin and fibrinogen to fibrin.
- By binding to the calcium ions, sodium citrate prevents these conversions from happening, thus inhibiting blood coagulation.
