Red Blood Cells
Dyskeratosis Congenita

Hemoglobinuria: Overview and Causes
Hemoglobinuria: Red urine from free hemoglobin, not whole RBCs. Signals serious issues like hemolysis. Prompt diagnosis is vital.

Hematuria: Blood in urine, gross (visible) or microscopic. Could signal infection, stones, or more serious issues.
Paroxysmal Cold Hemoglobinuria
Paroxysmal cold hemoglobinuria (PCH) is a rare autoimmune anemia. Cold exposure triggers red cell destruction, causing dark urine, back pain, and chills. Diagnosis relies on the Donath-Landsteiner test.
Paroxysmal Nocturnal Hemoglobinuria (PNH)
Paroxysmal nocturnal hemoglobinuria (PNH): An acquired blood disease where the immune system attacks red cells due to a mutation in the X chromosome.
Warm Autoimmune Hemolytic Anemia (warm AIHA)
Warm AIHA: Immune system attacks red blood cells, causing anemia. Symptoms include fatigue, pallor, and jaundice. Treatment targets immune suppression.
