Evaluation of Platelet Count by Different Methods in Hyperlipidemia Specimens.

Area of Science:

• Hematology
• Clinical Chemistry
• Medical Diagnostics

Background:

• Platelet count is a critical biomarker for various diseases and treatment outcomes.
• Hyperlipidemia can interfere with accurate platelet count measurements.
• Evaluating diagnostic methods for lipemic samples is essential for reliable clinical interpretation.

Purpose of the Study:

• To assess the accuracy of three platelet counting methods (impedance, optical, fluorescence) in hyperlipidemia samples.
• To compare the performance of Plt-I, Plt-O, and Plt-F in lipemic blood.
• To determine the most reliable method for platelet enumeration in the presence of high lipid concentrations.

Main Methods:

• Sixty whole blood samples were analyzed, categorized into low, medium, and high platelet count groups.
• Lipemia was induced by exchanging plasma with fat emulsion.
• Platelet counts were measured using impedance (Plt-I), optical (Plt-O), and fluorescence (Plt-F) methods.

Main Results:

• The fluorescence method (Plt-F) met predefined acceptance criteria for accuracy in all platelet count groups after lipemia induction.
• The optical method (Plt-O) failed to meet accuracy criteria in the low platelet count group.
• Both Plt-I and Plt-O showed limitations in accurately quantifying platelets in lipemic samples compared to Plt-F.

Conclusions:

• The fluorescence method (Plt-F) is superior for accurately determining platelet counts in lipemic specimens.
• Plt-F provides more reliable results than Plt-I and Plt-O for patients with hyperlipidemia.
• Accurate platelet count measurement in lipemic samples is vital for clinical decision-making.
