Delayed blood smear preparation caused artifactual platelet clumping, mimicking pseudo thrombocytopenia. This condition, termed pseudo pseudothrombocytopenia, is distinct from true platelet clumping disorders.

Area of Science:

  • Hematology
  • Clinical Pathology

Background:

  • Thrombocytopenia, a condition characterized by low platelet counts, can be challenging to diagnose.
  • Pseudo thrombocytopenia is a common laboratory artifact that can lead to misdiagnosis.

Observation:

  • An 82-year-old male presented with thrombocytopenia and platelet clumping on blood smear.
  • Initial assessment suggested pseudo thrombocytopenia, an artifact caused by ethylenediaminetetraacetic acid (EDTA).

Findings:

  • The observed platelet clumping was determined to be a result of delayed blood smear preparation, not EDTA-induced clumping.
  • This artifactual platelet clumping was termed pseudo pseudothrombocytopenia.

Implications:

  • Distinguishing pseudo pseudothrombocytopenia from true thrombocytopenia and pseudo thrombocytopenia is crucial for accurate diagnosis.
