Differentiating Pancytopenia from Other Diseases

  • Pancytopenia must be differentiated from a pseudo-syndromes like pseudo-thrombocytopenia, which is a laboratory artifact from platelet clumping.
  • There are no other mimickers of pancytopenia, as the diagnosis can be unequivocally established by laboratory testing (complete blood count).
