A new sedimentation method accurately counts human blood platelets using a specialized fluid mixture and centrifugation. This technique enables precise platelet quantification for research and diagnostics.

Area of Science:

Hematology
Biotechnology
Medical Diagnostics

Background:

Accurate human blood platelet counting is crucial for diagnosing and monitoring various medical conditions.
Existing platelet counting methods may have limitations in precision or accessibility.

Purpose of the Study:

To introduce and validate a novel sedimentation-based method for human blood platelet enumeration.
To establish a reliable and efficient protocol for platelet counting.

Main Methods:

Development of a specialized counting fluid with a specific gravity of 1.057 and osmolarity of 320 milliosmols.
Utilizing a mixture of Lymphoprep and Isoton II as the sedimentation fluid.
Employing centrifugation followed by electronic particle counting for platelet quantification.
