79. A method for transferring a reagent to an assay unit, comprising:
-
A) inserting a cartridge into an instrument, wherein the cartridge comprises i) an identifier, ii) an assay unit configured to run a chemical reaction that yields a signal indicative of an analyte, and iii) a reagent unit comprising a reagent, and wherein the instrument comprises a fluid transfer device comprising a programmable processor and a head configured to adhere to a pipette tip; B) reading the identifier on the cartridge and transmitting the identity of the identifier from the instrument to an external device; C) receiving by the programmable processor of the fluid transfer device a protocol from the external device, wherein the protocol is associated with the identifier and comprises instructions for transferring the reagent to the assay unit; D) transferring by the fluid transfer device a selected volume of the reagent to the assay unit, wherein the selected volume is provided in the protocol, and wherein the fluid transfer device is operable to transfer different volumes of the reagent into the assay unit. - View Dependent Claims (80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92)

93. A system for automated transfer of a reagent to an assay unit, comprising:
-
A) a cartridge, comprising;
i) an identifier;
ii) an assay unit configured to run a chemical reaction that yields a signal indicative of an analyte; and
iii) a reagent unit comprising a reagent; andB) an instrument, comprising a fluid transfer device containing a programmable processor and a head configured to adhere to a pipette tip; and wherein the instrument is configured to receive the cartridge, to read the identifier on the cartridge, and to transmit the identity of the identifier to an external device, wherein the programmable processor of the fluid transfer device is configured to receive a protocol from the external device comprising instructions for transferring the reagent to the assay unit, and wherein the fluid transfer device is operable to transfer different volumes of the reagent into the assay unit and to, based on the protocol, transfer a selected volume of reagent to the assay unit. - View Dependent Claims (94, 95, 96, 97, 98, 99, 100, 101, 102)

103. A method for automated dilution of a bodily fluid sample, comprising:
-
A) inserting a cartridge into an instrument, wherein the cartridge comprises i) an identifier, ii) a diluent unit comprising a diluent, and iii) a bodily fluid sample, and the instrument comprises a fluid transfer device comprising a programmable processor and a head configured to adhere to a pipette tip; B) reading the identifier on the cartridge and transmitting the identity of the identifier from the instrument to an external device; C) receiving by the programmable processor of the fluid transfer device a protocol from the external device, wherein the protocol is associated with the identifier and comprises instructions for the dilution of the bodily fluid sample; D) combining by the fluid transfer device a selected volume of the diluent with a selected volume of the bodily fluid sample to generate a diluted bodily fluid sample, wherein the selected volume of the diluent and the selected volume of the bodily fluid sample are provided in the protocol, and wherein the fluid transfer device is operable to combine different volumes of the diluent with different volumes of the bodily fluid sample. - View Dependent Claims (104, 105, 106, 107, 108)
