Predictive models in near-infrared spectroscopic analysis for blood hemoglobin prediction

Determination of blood hemoglobin concentration is important to diagnose anaemia. Common clinical practice used to measure blood hemoglobin is by drawn some blood from the patient to be mixed with reagent chemicals for analysis. Alternatively, near-infrared spectroscopy (NIRS) technology can be used...
