BScountToPctParasitemia(BScount, WBCdenominator = 300, WBCperML = 8000, RBCperML = 5e+06)
pctParasitemiaToBScount(pctParasitemia, WBCdenominator = 300, WBCperML = 8000, RBCperML = 5e+06)
BScountPerML(BScount, WBCdenominator = 300, WBCperML = 8000)

Arguments

BScount

Vector of parasite densities, given as the number of parasites per fixed number of white blood cells (WBC).

pctParasitemia

Vector of parasite densities, given as the percentage of red blood cells that are infected.

WBCdenominator

The fixed number of WBC used as the denominator when giving parasite density as a blood smear (BS) count.

WBCperML

The number of WBC per millileter (ML) of blood. A value taken from an explicit assay such as a CBC machine is prefered. Dufault is a typical average count.

RBCperML

The number of red blood cells (RBC) per millileter of blood. A value taken from an explicit assay such as a CBC machine is prefered. Dufault is a typical average count.

Details

The functions are written such that CBC machine values can be used directly, where any invalid or missing CBC values will be replace by default values.

Value

A vector of converted parasite density measurements in the desired units.
