Abstract
The invention provides a reagent supply system including a reagent rack for retaining a plurality of vials. The rack has a base and first and second walls extend upwardly from the base. The first wall includes an abutment extending toward the second wall and adapted to engage a first recess on one of the vials, while the second wall includes a flexible clip having a shoulder thereon, the shoulder being biased toward a position adapted to engage a second recess on the vial. The invention also provides a method of handling reagents which includes providing a variable reagent rack adapted to retain a plurality of vials and a common reagent pack containing a plurality of predetermined common reagents adapted to coact with reagents in the vials. A patient fluid is provided and a plurality of assays to be performed on that fluid are determined. Vials are then selected, each vial containing a different assay-specific reagent necessary for one of the assays, and the selected vials are loaded onto the rack. A quantity of reagent from one the vials and a quantity of a common reagent from the common reagent pack are transferred into a reaction vessel. A quantity of reagent from a second vial and a quantity of the common reagent are transferred into a second reaction vessel.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
