Among the blood counts, platelet count is most often reported with inconsistency.Many of the analyzers work on electrical impedance principle for red blood cell (RBC) and platelet counting.However, with this technology, factors such as fragmented RBCs, microcytes, cytoplasmic fragments of leukemic cells, lipid particles, fungal yeast forms, and bacteria are known to interfere with platelet count and give spuriously elevated Faber Daisy B EG6 A55 55cm Angled Cooker Hood Black Glass 330 0529 664 platelet counts.A 72-year-old male was admitted for the treatment of dengue infection who had serial platelet Inserts count monitoring.He had an initial platelet count of 48,000/cumm which suddenly improved to 2.

6 lakhs within 6 h without any platelet transfusion.Peripheral smear however did not correlate with the machine-derived count.Repeat test after 6 h yielded a result of 56,000/cumm which correlated well with the peripheral smear.This falsely elevated count was due to the presence of lipid particles as the sample was drawn in the postprandial state.
