1. A sample analysis cartridge for the voltammetric detection of a fluid parameter in a fluid sample, the sample cartridge being releasably insertable in a voltammetric detection device, and comprising:
at least one sample analysis reservoir operable to receive an end portion of a fluid collection device that is used for the releasable collection of the fluid sample, the sample analysis reservoir comprising:
a first compartment containing an activating compound or an electroactive analyte that is activatable by the activating compound when the activated compound is activated by the fluid parameter in the fluid sample to form an activated electroactive analyte, the first compartment having an opening at an upper end;
a second compartment containing the electroactive analyte that is activatable by the activated activating compound to form the activated electroactive analyte when the first compartment contains the activating compound, or the second compartment contains the activating compound when the first compartment contains the electroactive analyte; and
a penetrable barrier disposed between the first and second compartments to fluidically separate the first and second compartment; and
a voltammetric sensor disposed at least partially within the second compartment.
