Clinical Pathology and Transfusion Medicine Quiz

Impact of Maximizing ATP Synthesis in Red Cells

• Enhancing ATP synthesis in red blood cells (RBCs) improves their energy levels, supporting membrane integrity and function.
• Higher ATP levels contribute to better cell survival by maintaining ion gradients and flexibility, crucial for navigating capillaries.
• Improved ATP synthesis can increase the lifespan of red cells in circulation, reducing the risk of hemolysis.

Anticoagulant Solutions for Red Cell Storage

• Citrate Phosphate Dextrose (CPD) and Acid-Citrate-Dextrose (ACD) solutions are commonly utilized to prolong the life of red blood cells.
• These anticoagulants prevent clotting during storage, helping maintain red cell viability for transfusion.

Contribution of Anticoagulant Solutions in Minimizing Storage Lesions

• Anticoagulant solutions help mitigate storage lesions by offering nutrients and maintaining pH balance during storage.
• They reduce the accumulation of metabolic byproducts, which can lead to cell damage over time.
• By promoting better energy utilization and metabolic processes, these solutions support the preservation of red cell functionality.

Shelf Life of Blood Components with Red Cells

• Blood components containing red cells typically have a shelf life of 21 days when using CPD or ACD anticoagulants.
• Extensions in storage time can vary based on specific conditions and additives, but standard practices observe this 21-day limit.

Function of Citrate as an Anticoagulant

• Citrate acts as an anticoagulant by binding calcium ions, which are essential for the coagulation cascade.
• This action effectively inhibits thrombus formation, allowing for the safe collection and storage of blood products.
• Citrate also contributes to maintaining a suitable environment within the blood bag, preserving red cell viability.
