The effect of oscillation depolymerization on ethylenediaminetetraacetic acid-dependent platelet aggregation samples:...

Area of Science:

• Hematology
• Clinical Pathology
• Biomedical Engineering

Background:

• Ethylenediaminetetraacetic acid (EDTA)-dependent platelet aggregation (PA) is a common issue in clinical practice.
• Existing methods for resolving EDTA-PA are unreliable, leading to potential medical errors.
• A novel approach is needed to effectively address EDTA-PA.

Purpose of the Study:

• To evaluate the efficacy of the oscillation method in disaggregating EDTA-PA.
• To determine the optimal parameters for the oscillation method.
• To assess the impact of the oscillation method on other blood cell components.

Main Methods:

• Sixty-one EDTA-PA samples were subjected to the oscillation method at varying speeds and durations.
• Samples were analyzed using routine blood tests and blood smear examinations.
• Disaggregation rates were compared between the oscillation method and sodium citrate anticoagulant.

Main Results:

• Oscillation significantly increased platelet counts (PLT) in EDTA-PA samples.
• Optimal disaggregation was observed at 3000 rpm for 0.5 minutes.
• The oscillation method achieved an effective disaggregation rate of 96.72%, significantly higher than sodium citrate (65.57%).
• No significant adverse effects on white blood cell (WBC) or red blood cell (RBC) counts or morphology were observed.

Conclusions:

• The oscillation method is a highly effective technique for depolymerizing EDTA-PA.
• This method shows no detrimental effects on WBC and RBC, ensuring sample integrity.
• The oscillation method presents a promising solution to overcome the long-standing challenge of EDTA-PA in clinical settings.
