Use Platelet Count Correction when you need to correct a counted platelet number by the dilution factor and the number of counting chambers. Enter Counted platelets, Dilution factor, and Counting chambers using the definitions and units below so the result can be reproduced.

Counted platelets

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.

Counting chambers

An integer count or setting greater than or equal to 1.

The published tool contract uses this rule: Correct a counted platelet number by the dilution factor and the number of counting chambers.

Corrected platelets

The calculated corrected platelets in K/uL.

The calculation does not propagate measurement uncertainty, sampling error, or biological and chemical variability.

Retain the original Counted platelets, Dilution factor, and Counting chambers values and their units alongside the result. Corrected Retic Percent is useful when you instead need to correct the reticulocyte percent for anemia by multiplying by the patient to normal hematocrit ratio with a reference normal hematocrit of 45 percent. Red Cell Concentration provides another view by helping you convert cells counted in a hemocytometer square into a red cell concentration in millions per microliter using countedCells x dilutionFactor / 10.

• Corrected Retic Percent
