🌹 Blood Product Components in Blood Bank
🌹 Red Blood Cell Components🌹
✅ PRC (Packed Red Cells)
🩸 Concentrated red blood cells used to improve oxygen delivery to tissues in patients with anemia or blood loss, according to clinical indications.
✅ LPRC (Leukocyte-Poor Red Cells)
🩸 Red blood cells with a reduced leukocyte count. They may help reduce the risk of certain transfusion reactions, such as Febrile Non-Hemolytic Transfusion Reaction (FNHTR). Their effectiveness depends on the product preparation process and the degree of leukocyte reduction.
✅ LDPRC (Leukodepleted Packed Red Cells)
🩸 Packed red blood cells that have undergone leukocyte reduction according to standard criteria. They help reduce the risk of FNHTR, HLA alloimmunization, and leukocyte-associated Cytomegalovirus (CMV) transmission, but these risks cannot be completely eliminated.
💐 Plasma Components💐
✅ FFP (Fresh Frozen Plasma)
❄️ Plasma frozen within the specified time after blood collection to preserve coagulation factors. It is used to replace multiple coagulation factors in patients with clinical indications.
✅ LDFFP (Leukodepleted Fresh Frozen Plasma)
❄️ Fresh frozen plasma that has undergone leukocyte reduction according to product specifications, with coagulation factors meeting the specified quality criteria.
🩺 Clinical Use
Used to replace multiple coagulation factors in patients with clinical indications, based on coagulation factor deficiencies, the severity of bleeding, and appropriate treatment guidelines.
✅ Cryoprecipitate
🧬 A plasma component containing high concentrations of certain proteins and coagulation factors, including:
🩸 Fibrinogen (Factor I): An essential precursor for clot formation.
🩸 Factor VIII: An important factor in the blood coagulation process.
🩸 von Willebrand factor (vWF): Helps platelets adhere to injured blood vessel walls and stabilizes Factor VIII.
🩸 Factor XIII: Helps strengthen and stabilize blood clots.
🩸 Fibronectin: A protein involved in cell adhesion and tissue repair.
🩺 Clinical Use
Used to replace fibrinogen in patients with low fibrinogen levels and clinical indications, according to treatment guidelines and the availability of appropriate products.
🌺 Platelet Components🌺
✅ PC (Platelet Concentrate)
🩸 Random PC (Platelet Concentrate)
Platelets separated from a single blood donor. Each unit has a relatively small volume and contains some leukocytes. For adult patients, platelets from multiple donors are commonly pooled, usually around 4–6 units.
⚠️ Open System
After pooling, the product must be used within the time specified by the applicable standards, generally no longer than 4 hours.
🩺 Clinical Use
Used to prevent or treat bleeding in patients with low platelet counts or platelet function disorders, according to clinical indications.
✅ LPPC (Leukocyte-Poor Platelet Concentrate)
🩸 Platelet concentrates with a reduced leukocyte count.
These products undergo a process to reduce leukocytes. The Buffy Coat layers from 4–6 donors of the same blood group are often pooled and centrifuged again. The leukocyte count is reduced to some extent, but some leukocytes remain, potentially at higher levels than in LDPPC.
🩺 Clinical Use
Used to prevent or treat bleeding in patients with indications for platelet transfusion. Leukocyte reduction may help reduce the risk of FNHTR and HLA alloimmunization. The effectiveness depends on the degree of leukocyte reduction in the product.
✅ LDPPC (Leukodepleted Pooled Platelet Concentrates)
🩸 Pooled platelet concentrates that have undergone leukocyte reduction.
A specialized leukocyte filter is used after pooling to remove leukocytes, leaving only a very small number. This product undergoes a high degree of leukocyte reduction.
🩺 Clinical Use
Used to prevent or treat bleeding in patients with indications for platelet transfusion. Leukocyte reduction helps reduce the risk of FNHTR and HLA alloimmunization, but it does not eliminate all leukocytes or prevent every type of transfusion reaction.
✅ SDP (Single Donor Platelets)
🩸 Platelets collected from a single donor.
Platelets are collected from one donor using an Apheresis machine. One adult unit generally provides a platelet dose comparable to several units of platelets derived from whole-blood donations, depending on the platelet content of the product.
🩺 Clinical Use
Used to prevent or treat bleeding in patients with clinical indications.
✅ LDSDP (Leukodepleted Single Donor Platelets)
🩸 Single-donor platelets that have undergone leukocyte reduction.
Platelets collected from a single donor using an Apheresis machine and processed to reduce leukocytes according to product specifications.
🩺 Clinical Use
Used to prevent or treat bleeding in patients with clinical indications. Leukocyte reduction helps reduce the risk of FNHTR and HLA alloimmunization, but it cannot eliminate all transfusion-related risks.
🌡️ Platelet Storage
Platelets must be stored at the temperature and un
