# S3 method for class 'numeric'
anemia(Hb, age, male, ...)

Arguments

...: Further optional arguments
.data: (data.frame) A data.frame, optional
Hb: Hemoglobin concentration column name, or vector of units or numeric if .data is not provided
age: Age of patient column name, or vector of units or numeric if .data is not provided
male: Male or not column name, or vector of logical (TRUE/FALSE) if .data is not provided

Value

Anemia as logical TRUE or FALSE

Details

Adults and children >15 years with CKD when the Hb concentration is <13.0 g/dl (<130 g/l) in males and <12.0 g/dl (<120 g/l) in females.
Children with CKD if Hb concentration is <11.0 g/dl (<110 g/l) in children 0.5-5 years, <11.5 g/dl (115 g/l) in children 5-12 years, and <12.0 g/dl (120 g/l) in children 12-15 years.
