Red Cell Concentration
Convert cells counted in a hemocytometer square into a red cell concentration in millions per microliter using countedCells x dilutionFactor / 10.
Description
Convert cells counted in a hemocytometer square into a red cell concentration in millions per microliter using countedCells x dilutionFactor / 10.
Red Cell Concentration is a focused biology tool that convert cells counted in a hemocytometer square into a red cell concentration in millions per microliter using countedCells x dilutionFactor / 10. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use Red Cell Concentration
Use Red Cell Concentration when you need to convert cells counted in a hemocytometer square into a red cell concentration in millions per microliter using countedCells x dilutionFactor / 10. Enter Counted cells and Dilution factor using the definitions and units below so the result can be reproduced.
- Counted cells
- A finite measured or assumed value greater than or equal to 0.
- Dilution factor
- A finite measured or assumed value greater than or equal to 1.
How Red Cell Concentration calculates the result
The published tool contract uses this rule: Convert cells counted in a hemocytometer square into a red cell concentration in millions per microliter using countedCells x dilutionFactor / 10.
- Red cell concentration
- The calculated red cell concentration in million/uL.
Limitations of Red Cell Concentration
A ratio or percentage can conceal the scale of its numerator and denominator and becomes sensitive to measurement error when the denominator is small.
Alternative or Complementary measurements
Retain the original Counted cells and Dilution factor values and their units alongside the result. RDW-CV Percent is useful when you instead need to compute red cell distribution width CV from RBC volume standard deviation and MCV. Red Cell Mass mL provides another view by helping you compute the red cell mass as blood volume times the hematocrit fraction.
