1. A disposable, single use test cell for receiving a fluid to be diagnostically tested by an instrument, the test cell comprising:
- a housing sized and shaped for engagement by the instrument when a diagnostic test is to be performed, the housing including a least one chamber, a first bore in fluid communication with the at least one chamber and a second bore in fluid communication with the at least one chamber;
a pair of electrodes within the at least one chamber for performing ion selective analysis, the electrodes being in electrical contact with circuitry within the instrument when the housing is engaged by the instrument;
a calibration capsule within the first bore, the calibration capsule containing calibration fluid for calibrating the electrodes; and
a specimen capsule within the second bore, the specimen capsule containing the fluid to be tested whereby calibration fluid from the calibration capsule flows from the first bore to the at least one chamber for calibration of the electrodes and the fluid to be tested flows from the specimen capsule through the second bore to the at least one chamber for analysis by the electrodes.

17. A disposable, single use test cell for receiving a fluid to be diagnostically tested by an instrument, the test cell comprising:
-
a housing sized and shaped for engagement by the instrument when a diagnostic test is to be performed, the housing including two elongated chambers of substantially the same dimensions and length and a bore in fluid communication with both chambers;
a first pair of electrodes with each electrode of the first pair being located at an end of one of the chambers, the electrodes of the first pair being in electrical contact with circuitry within the instrument when the housing is engaged by the instrument;
a second pair of electrodes with each of the electrodes of the second pair being located at an end of the other chamber, the electrodes of the second pair being in electrical contact with circuitry within the instrument when the housing is engaged by the instrument; and
a specimen capsule within the bore, the specimen capsule containing the fluid to be tested whereby the fluid to be tested flows from the specimen capsule and into the two chambers, the fluid flowing into one of the chambers being subjected to a lysing agent prior to flowing into the one chamber. - View Dependent Claims (18, 19, 20, 21)
