Claim:
1. A method of performing a plurality of general chemistry assays on a blood sample obtained from a subject, comprising: (i) receiving in a biological sample processing device a cartridge comprising the blood sample obtained from a subject, wherein the blood sample is about 200 μl or less and the cartridge further comprises: wherein the biological sample processing device comprises: (ii) aspirating at least a portion of the biological sample with the pipette and dispensing the at least a portion of the biological sample to each of the at least 14 cuvettes with the pipette; (iii) aspirating a chromogen with the pipette and dispensing the chromogen to a cuvette with the pipette, and repeating the aspirating and dispensing step with the remaining chromogens, wherein each of the at least 14 cuvettes comprises the inert liquid and the inert liquid forms a layer on top of the sample and chromogen; (iv) engaging the at least one pipette head with at least one of the at least 14 cuvettes and moving with the pipette head the at least one cuvette from the cartridge to the at least one detection unit; and (v) detecting signals indicative of the presence or absence of the at least 14 different analytes with the at least one detection unit; wherein the at least 14 general chemistry assays do not use an antibody and do not assay for a nucleic acid, and the at least 14 different analytes comprise glucose, calcium, albumin, total protein, sodium, potassium, chloride, carbon dioxide, creatinine, blood urea nitrogen (BUN), alkaline phosphatase (ALP), alanine aminotransferase (ALT/GPT), aspartate aminotransferase LAST/GOT), and total bilirubin.
