Living with Adult pure red cell aplasia

A rare blood condition in which the bone marrow almost stops making red blood cells, causing severe anemia.

Understanding Adult pure red cell aplasia

Adult pure red cell aplasia is a rare acquired type of aplastic anemia with a severe drop in red blood cells.

White blood cell and platelet counts are normal, but the bone marrow almost completely lacks the cells that become red blood cells. It causes signs of severe anemia but not bleeding.

Signs & symptoms

Symptoms vary from person to person. GARD's summary says they include:

  • Tiredness (fatigue)
  • Lack of energy (lethargy)
  • Pale skin (pallor)
  • Trouble with physical exercise
  • Shortness of breath with activity

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include blood and bone marrow specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Aplastic Anemia and MDS International Foundation and Autoimmune Association may keep lists of experts for this condition.
