Some embodiments of the invention provide a joint-diagnostic spectroscopic and biosensor meter for providing results from analysis of a fluid sample, e.g. blood, using a disposable microfluidic cartridge. The meter comprises: (a) a housing; (b) at least one source of electromagnetic radiation (EMR); (c) a slot in the housing of the meter for receiving the cartridge, the cartridge comprising at least one optical chamber and at least one biosensor chamber, wherein the at least biosensor chamber comprises at least one biosensor; (d) at least one photodetector for measuring EMR transmitted through or reflected from the fluid sample; (e) a circuit board in operative association with the at least one biosensor and the at least one photodetector; and (f) a processor for preparing the results. In the specific embodiments of the invention, all the sample flow paths are restricted within the microfluidic cartridges and therefore, there is no fluid connection between the microfluidic cartridges and the meter. Moreover, there is no permanent installation of a cartridge in the meter. Once the blood is transferred to the cartridge, the cartridge is inserted into the slot of the meter for rapid blood analysis. The meter can be made in the form of an inexpensive hand-held instrument for point-of-care testing.
