# S3 method for units

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.
