Use Mitotic Index % when you need to calculate the mitotic index as the percentage of counted cells in mitosis. Enter Cells in mitosis and Total cells using the definitions and units below so the result can be reproduced.

Cells in mitosis

A finite measured or assumed value.

Total cells

A finite measured or assumed value.

The published tool contract uses this rule: Calculate the mitotic index as the percentage of counted cells in mitosis.

Mitotic index

The calculated mitotic index in %.

A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.

Retain the original Cells in mitosis and Total cells values and their units alongside the result. Phase Mitotic Fraction is useful when you instead need to compute the fraction of cells positive for a specific mitotic phase marker. Apoptotic Index provides another view by helping you compute the apoptotic index as the ratio of apoptotic cells to mitotic cells.

• Phase Mitotic Fraction

  Compute the fraction of cells positive for a specific mitotic phase marker.

• Apoptotic Index

  Compute the apoptotic index as the ratio of apoptotic cells to mitotic cells.

• Necrotic Index

  Compute the percentage of necrotic cells in a counted cell population.
