Background: The need for a simple and more accurate malaria diagnosis and parasite density determination cannot
be over-emphasized at such a time when there is increased infection prevalence and higher mortality rate as reported
by the World Health Organization. Objective: This article highlights the simple novel approach in using the ‘first
principle’ protocol on malaria parasite density determination. Methods: The protocol based on the first principle
on malaria parasite quantification was used. The diameter of the field of view (dFOV, 0.178 mm) multiplied by
100 fields gives the diameter of the circle of thick blood film required. The volume of blood in the thick film is equal
to the diameter of the circle of thick blood film divided by the volume of blood used (8 μL) and further divided by the
