Determine inflammation status

Description

Given laboratory values for serum c-reactive proteint (CRP) and/or serum alpha(1)-acid-glycoprotein (AGP), the inflammation status of a subject can be determined based on cut-off values described in Namaste, S. M., Rohner, F., Huang, J., Bhushan, N. L., Flores-Ayala, R., Kupka, R., Mei, Z., Rawat, R., Williams, A. M., Raiten, D. J., Northrop-Clewes, C. A., & Suchdev, P. S. (2017). Adjusting ferritin concentrations for inflammation: Biomarkers Reflecting Inflammation and Nutritional Determinants of Anemia (BRINDA) project. The American journal of clinical nutrition, 106(Suppl 1), 359S–371S. https://doi.org/10.3945/ajcn.116.141762

Usage

detect_inflammation(crp = NULL, agp = NULL)

detect_inflammation_crp(crp)

detect_inflammation_agp(agp)

Arguments

crp	A numeric value or numeric vector of c-reactive protein (crp) values in micrograms per litre (µg/l).
agp	A numeric value or numeric vector of alpha(1)-acid-glycoprotein (agp) values in micrograms per litre (µg/l).

Value

A character value or character vector of inflammation classification based on c-reactive protein (CRP) and/or alpha(1)-acid-glycoprotein (AGP) values.
