Determine iron storage status

Description

Given serum ferritin values, determine iron storage status.

Usage

detect_iron_deficiency_u5(ferritin = NULL)

detect_iron_deficiency_5over(ferritin = NULL)

detect_iron_deficiency(ferritin = NULL, group = c("u5", "5over"))

detect_iron_deficiency_qualitative(ferritin = NULL, inflammation = NULL)

Arguments

ferritin	A numeric value or numeric vector of serum ferritin level in micrograms per liter (µg/l).
group	A character value specifying the population target group to determine iron status from. Can be either for under 5 year old ("u5") or 5 years and over ("5over"). Default to "u5".
inflammation	Logical value or vector. Is subject in inflammation or not?

Value

A character value or character vector of iron status. Can be either "iron deficiency" or "no iron deficiency".

Examples

 # Iron storage status based on CRP only
 ferritin_corrected <- correct_ferritin(
   crp = ferritin$crp, ferritin = ferritin$ferritin
 )
 detect_iron_deficiency(ferritin_corrected)

 # Iron storage status based on AGP only
 ferritin_corrected <- correct_ferritin(
   agp = ferritin$agp, ferritin = ferritin$ferritin
 )
 detect_iron_deficiency(ferritin_corrected)

 # Iron storage status based on CRP and AGP
 ferritin_corrected <- correct_ferritin(
   crp = ferritin$crp, agp = ferritin$agp, ferritin = ferritin$ferritin
 )
 detect_iron_deficiency(ferritin_corrected)

 # Iron storage status - qualitative
 detect_iron_deficiency_qualitative(
   ferritin = 3, inflammation = TRUE
 )
 detect_iron_deficiency_qualitative(
   ferritin = c(2, 3, 5), inflammation = c(TRUE, FALSE, TRUE)
 )
