Abstract
EDTA-dependent pseudothrombocytopenia (PTCP) is the phenomenon of a
low platelet count due to EDTA-induced aggregation of platelets. Since the failure to
recognize EDTA-dependent PTCP may result in incorrect diagnosis and inappropriate
treatment, the recognition of this phenomenon is very important in managing the
patient and giving correct treatment. We here by discuss about a case of, A 21 year
old male admitted for fever for evaluation showed severe thrombocytopenia by
automated 5 part Mindray analyser. Manual count and peripheral smear done revealed
higher count and small platelet aggregates. Following which citrated sample was
collected and manual counting done both showed similar values, low count in singles
without aggregation when compared to EDTA sample. EDTA induced platelet
aggregation was thus conformed.
