BScountToPctParasitemia | R Documentation |
Conversion routines for quantifying parasite density in any of several standard methods, as measured by assays like thin or thick smear by microscopy.
BScountToPctParasitemia(BScount, WBCdenominator = 300, WBCperML = 8000, RBCperML = 5e+06)
pctParasitemiaToBScount(pctParasitemia, WBCdenominator = 300, WBCperML = 8000, RBCperML = 5e+06)
BScountPerML(BScount, WBCdenominator = 300, WBCperML = 8000)
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. |
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.
A vector of converted parasite density measurements in the desired units.
