MCV Cross Check
Cross check a reported MCV against the computed mean corpuscular volume hematocrit x 10 / RBC and flag agreement within two femtolitres.
Description
Cross check a reported MCV against the computed mean corpuscular volume hematocrit x 10 / RBC and flag agreement within two femtolitres.
MCV Cross Check is a focused biology tool that cross check a reported MCV against the computed mean corpuscular volume hematocrit x 10 / RBC and flag agreement within two femtolitres. It calculates locally from the values you enter and exposes the result without changing the source observations.1
When to use MCV Cross Check
Use MCV Cross Check when you need to cross check a reported MCV against the computed mean corpuscular volume hematocrit x 10 / RBC and flag agreement within two femtolitres. Enter Hematocrit, RBC count, and Reported MCV using the definitions and units below so the result can be reproduced.
- Hematocrit
- A finite measured or assumed value, expressed in %.
- RBC count
- A finite measured or assumed value, expressed in million/µL.
- Reported MCV
- A finite measured or assumed value, expressed in fL.
How MCV Cross Check calculates the result
The published tool contract uses this rule: Cross check a reported MCV against the computed mean corpuscular volume hematocrit x 10 / RBC and flag agreement within two femtolitres.1
- Computed MCV
- The calculated computed mcv in fL.
- Consistent
- True when the reported MCV agrees within two femtolitres.
Limitations of MCV Cross Check
The category is produced by fixed software thresholds. Those cutoffs may differ from a laboratory, field protocol, population, jurisdiction, or current professional guideline.
Alternative or Complementary measurements
Retain the original Hematocrit, RBC count, and Reported MCV 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.
