In hemat: Hematimetric Indices Calculator

#' Calculate Mean Corpuscular Hemoglobin (MCH)
#'
#' Calculates the MCH based on hemoglobin concentration and red blood cell count.
#' MCH measures the average amount of hemoglobin per red blood cell.
#' @param hb Numeric value representing the hemoglobin concentration in g/dL.
#' @param rb Numeric value representing the red blood cell count (millions/ µL).
#' @returns Numeric value representing the MCH in picograms (pg).
#' @examples calc_mch(15, 5)
#' @export
