HPFitis is use of HPF (high-power field) without proper qualification, i.e. without giving the field area.

HPF redirects here.

Etiology

Its etiology is thought to be either:

  1. Ignorance of statistics and sampling theory.
  2. Laziness.
  3. A combination of the above two.

It appears to have a higher incidence in math phobic individuals.

Consequences of HPFitis

Field area

Most modern microscopes, have an eye piece diameter of 22 mm. Therefore, the field diameter at 40 X is approximately 22 mm / 40 X ~= 0.55 mm and the field of view is pi/4*(0.55 mm)2 = 0.2376 mm2.
