Reagent Delivery Components In this section, you identified the components of the Reagent Delivery System: Autoloader R1 and R2 Probes R1 and R2 Pump Panels Refer to each section within this course if you need to review the components and their functionality.   Monitoring Reagent Inventory The operator can access the Reagent Cartridge Inventory screen by selecting Alt/I which displays the Method and Lot, Tests Left and both Calibration and System Expiration Dates. Once loaded, unopened reagents have a minimum of 30 days stability, and each well also has an expiration time. The instrument also checks for reagent needs every time RUN is pressed. If a Red Check Needs icon appears, Alt/N will display the System Needs and the F1: REAGENT function key will become active to indicate the reagent need. Supplies Alert (Dimension® Xpand® Plus) provides a proactive warning to alert the operator when levels are below a preset limit that is defined by your laboratory. Adding and Removing Reagents Flex® reagent cartridges can be loaded through the autoloader even while the system is processing.  When loading Flex® reagent cartridges, position the barcode on the right and the narrow end forward.  During loading, the red load light remains on. If unsuccessful, the loader light blinks and the reagent manager icon appears on the screen. Selecting Alt/R displays the reason for this icon. If the reason is due to a third lot of reagent, the Flex® reagent cartridge will be placed into HOLD status until the operator replaces an old lot with the new lot. Reagents will be removed automatically when expired or empty.  To remove a Flex® reagent cartridge manually, from the Reagent Cartridge Inventory screen, press F3: REMOVE REAG. After removing the reagent, press F1: CONFIRM REMOVE to confirm the removal. Hydration The Dimension® system automatically hydrates Flex® reagent cartridges, as needed, to complete all requested tests. Use the Hydration By Lot screen to hydrate specific lots of Flex® reagent cartridges. To hydrate Flex® reagent cartridges by selecting specific test methods, select the methods and enter the number of tests to be hydrated. Use the Inventory/Hydration screen to create or load a pre-programmed setup list of test methods that you want to hydrate. Pre-programming hydrations improves test turnaround times, maximizes instrument efficiency based on test volumes, and ensures that tableted Flex® reagent cartridges are ready to use during peak workloads. The system will hydrate up to the required number of tests based on this number. To hydrate Flex® reagent cartridges using a timed hydration schedule, load a setup and then set the hydration start day, time and frequency. Turn the Activated option to ON.  At the scheduled time, date, and frequency, the system hydrates the required number of Flex® reagent cartridges to satisfy the total number requested.  The instrument provides 5 and 1 minute warnings before hydration and alerts the operator when hydration has begun.   Select Next to continue.   Place the Flex® reagent cartridge into the autoloader so that the narrow end goes into the instrument first and the barcode label is on the right side of the cartridge. The barcode reader scans the barcode, and then the system moves the cartridge into the reagent tray. During the loading process, the red loader light will be lit. TIP: You can load reagents any time during processing or standby.  The Reagent Inventory screen does not need to be displayed to load reagents. Do not add any Flex® reagent cartridges that have been partially used.  Select Next to continue. If the autoloader will not insert the cartridge into the instrument, the loader light blinks, and a blinking reagent manager icon appears on the screen. If this occurs: Remove the Flex® reagent cartridge from the autoloader Press Alt/R to see why the cartridge could not be loaded and to remove the icon from the screen. Tip: Ctrl/Help provides an explanation of the Reagent Cartridge Status Icon options  Note: Depending on the version of software on your instrument, some screens may appear different; however, the functionality remains the same. Select Next to continue. The screen displays a blinking Reagent Manager icon when a third reagent lot is loaded onto the instrument. Selecting Alt/R provides the message:  A reagent cartridge has been added which will force calibration of a third lot. The cartridge has been stored as method “HOLD.”   A Flex® reagent cartridge designated as “HOLD” will not be used until it is confirmed for use. Note: Depending on the version of software on your instrument, some screens may appear different; however, the functionality remains the same.

Select Next to continue. In this section, you have the opportunity to think about these hydration FAQs. Read each question then review the corresponding answer.   Question Answer During a timed hydration, if some tests are already hydrated, what will the instrument do? The instrument will hydrate only enough tests to meet the hydration request. What happens if I get a STAT while the instrument is pre-hydrating? The instrument will pause the hydration, process samples with a STAT priority, and then automatically continue the hydration. Can I cancel a reagent hydration? Yes.   You can cancel a hydration by doing the following.  On the Hydration by Lot screen, press F5: DELETE.  Select Y to confirm that you want to cancel hydrations.  Hydrations in progress will be completed.  Hydrations not yet begun will be deleted. In what situation would I want to set up a timed hydration schedule? Suppose your facility receives the bulk of its workload from 6:00 - 8:30 A.M. daily and the average batch includes about 200 specimens.  Program a timed activated hydration to hydrate tests so that reagent is hydrated and available at 6 A.M. every day to process these samples. Can I load a setup list as many times as I want? Yes.  From the Inventory/Hydration screen, press F1 or F2 to recall either setup list and load it as many times as you need to hydrate the total number of tests required.  For example, if you press F1: LOAD SETUP twice to load the setup list for 200 BUN and 100 LDH tests, you would hydrate 400 BUN and 200 LDH tests.   The Dimension® Xpand®/Xpand® Plus integrated chemistry system hydrates reagents as needed to satisfy the test requests. Select Next to continue. Specific cartridge lots can be requested to hydrate by using the Hydration By Lot screen. For each Flex® reagent cartridge lot on the instrument, the Hydration By Lot screen shows the number of available tests of reagent that are hydrated, unhydrated, and to be hydrated.To access the Hydration by Lot screen and perform hydration, from the Operating Menu, select:   F4: System Prep F2: Reagent Prep Use test keys or cursor keys to select a method to hydrate Enter number of tests to hydrate in the No.Tests to be Hydrated column Enter Select additional methods to hydrate if necessary F4: Hydrate to begin hydration Note: Depending on the version of software on your instrument, some screens may appear different; however, the functionality remains the same. Select Next to continue. Before hydrating using a timed schedule, it is necessary to define and load a setup list and then activate the timed hydration. Pre-programming hydrations improves test turnaround times and maximizes instrument efficiency based on test volumes. Safety Tip: If your instrument is not currently processing samples when hydration begins, components will begin to move. The warning alerts you to keep your hands out of the instrument.
