1. A method for conducting an assay in a clinical analyzer, said method comprising the steps of:
- providing a plurality of first disposable metering tips;
providing a plurality of second disposable metering tips;
aspirating a volume of patient sample from a primary patient supply using one of said plurality of second disposable metering tips attached to a metering mechanism of said analyzer;
sealing the dispense end of said second disposable metering tip following aspiration of said volume of patent sample;
storing said sealed second disposable metering tip in an auxiliary patient sample supply as a sample container;
aspirating a volume of reagent from a reagent supply of said clinical analyzer using one of said plurality of first disposable metering tips as attached to a metering mechanism of said clinical analyzer;
dispensing the volume of reagent into a reaction vessel; and
discarding said first disposable metering tip.
