Abstract: Described are various embodiments of a point-of-care testing (POCT) system, analyzer and method for measuring quantities of at least two analytes in a blood sample, for example bilirubin and hemoglobin. The system comprises an analyzer and a removable cartridge. The removable cartridge comprises an optical chamber configured for receiving the blood sample. The analyzer comprises a receptor for receiving the removable cartridge, a first and second set of incident electromagnetic radiation (EMR) for example two broadband LEDs, an EMR dispersive element for example a reflective grating, a photo diode array detector, and a processor. The two EMR sources are implemented in such a way so that the spectral wavelength range of EMR emerging from the blood is expanded, and the effect of stray EMR is mitigated. The expanded wavelength range and the mitigation of stray EMR allows the analyzer to measure quantities of the analytes in lysed or unlysed blood.
