Blood Components Overview

Understanding the specifics of blood components is vital for effective transfusion medicine.

Here is a comprehensive guide to the four main types, their storage requirements, and clinical indications.

1. Packed Red Blood Cells (PRBC)

Composition:

  • Concentrated red blood cells
  • Hematocrit ~60–70%
  • Minimal plasma
  • Storage Temperature: 2–6°C (refrigerator)

Shelf Life: 35–42 days (depends on preservative solution)

When to Use:

  • Acute blood loss (hemorrhage)
  • Severe anemia (Hb <7 g/dL usually)
  • Pre/post-surgery anemia

2. Fresh Frozen Plasma (FFP)

Composition:

  • All clotting factors
  • Plasma proteins (albumin, globulins)
  • No cells
  • Storage Temperature: -18°C or colder (deep freezer)

Shelf Life:Up to 1 year

After thawing: use within 24 hours

When to Use:

  • Coagulation disorders (e.g., liver disease)
  • Disseminated Intravascular Coagulation (DIC)
  • Massive transfusion
  • Warfarin reversal (if no specific antidote available)

3. Platelet Concentrate

Composition:

  • Platelets suspended in small amount of plasma
  • Storage Temperature: 20–24°C (room temperature)
  • Continuous gentle agitation required

Shelf Life: 5–7 days

When to Use:

  • Thrombocytopenia (platelets <10,000–20,000)
  • Active bleeding with low platelets
  • Bone marrow failure, chemotherapy patients

4. Cryoprecipitate

Composition:

  • Fibrinogen
  • Factor VIII
  • Factor XIII
  • von Willebrand factor

Storage Temperature: -18°C or colder

Shelf Life: 1 year

After thawing: use within 6 hours

When to Use:

  • Hypofibrinogenemia
  • Massive bleeding (trauma, obstetrics)
  • Hemophilia A (if factor concentrate not available)
  • von Willebrand disease

Quick Memory Table

Component Temp Shelf Life Main Use

  • PRBC 2–6°C 35–42 days Anemia, blood loss
  • FFP ≤ -18°C, 1 year, Clotting factor deficiency
  • Platelets 20–24°C; 5–7 days; Low platelets
  • Cryo ≤ -18°C; 1 year; Low fibrinogen

Easy Memory Trick

‘RFP-C: Red, Factors, Platelets, Clot’

  • R denotes PRBC denotes Red cells
  • F denotes FFP denotes Factors
  • P denotes Platelets denotes Platelets
  • C denotes Cryo denotes Clotting (fibrinogen)”
