Mohammed Maher Babiker: When ‘Low Platelets’ aren’t Really Low

Mohammed Maher Babiker, Former Vice Head of Department at AL Burgaig Teaching Hospital, shared a post on LinkedIn:

“Don’t let EDTA fool you: When ‘low platelets’ aren’t really low!

In hematology, an accurate platelet count changes patient management. But EDTA, our most common anticoagulant, can create a false alarm called pseudothrombocytopenia.

Why platelet counts come back falsely low?

  1. Platelet clumping: EDTA exposes hidden epitopes – antibodies bind – platelets aggregate. Analyzer counts 1 clump as 1 cell.
  2. Cold agglutinins: Antibodies cause clumping at room temp.
  3. Pre-analytical errors: Delayed processing or poor mixing.
  4. Instrument limits: Aggregates misread as larger cells.
  5. Hemolysis: Interferes with accurate counting.

How to fix it and avoid patient harm:

  • Switch anticoagulant: Use citrate or heparin tubes for patients with known clumping.
  • Tighten handling: Mix well and process promptly.
  • Verify with a smear: Peripheral blood smear is the fastest way to spot clumps vs true thrombocytopenia.
  • Repeat testing: Fresh sample, different tube if results don’t match clinical picture.
  • Train the team: Staff awareness of EDTA artifacts prevents over-treatment.

A falsely low count can mean cancelled surgeries, unnecessary transfusions, or biopsies.

The fix is often just a smear and repeat tube.

Lab accuracy – better patient care.”
