An AI sales agent's VITROS analyzer reagent load, checked before it goes out

An AI sales agent prepares an order that adds an assay to a VITROS XT 7600, VITROS 5600 or VITROS XT 3400: the assay, the packs to add, what is already loaded in each reagent tray, the sample type and volume, the power supply and the room, and the total reagent positions it says will be in use. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures the public VITROS brochures list and returns a verdict, every reason and the figures it computed.

Scope: VITROS XT 7600, VITROS 5600 and VITROS XT 3400: reagent positions by technology, assay menu, sample type and volume, user-defined channels, automation interfaces, power and room conditions. See everything this validator covers

This validator models adding an assay to one analyzer at a time, based on the specifications and assay menus in the public VITROS XT 7600, VITROS 5600 and VITROS XT 3400 brochures, not just the scenarios shown below.

  • Reagent positions by technology — the three models have 89 MicroSlide cartridge positions; the XT 7600 and 5600 also have 31 MicroWell and 30 MicroTip pack positions (150 in all), and the XT 3400 has none for those. What is already loaded plus the packs added is compared with each limit.
  • Assay menu — 25 assays across the three technologies, each with its status on each model from the published menus: on the menu, not on the menu, or in development. The XT 3400 menu has MicroSlide chemistries only.
  • Sample rules — drugs-of-abuse assays are listed for urine, the CSF glucose assay for spinal fluid, whole blood only for hemoglobin A1c and red cell folate on the XT 7600 and 5600, and amniotic fluid is not commercially available in the United States; sample volume per assay must be inside the model range (XT 7600 and 5600: 2 to 80 microliters; XT 3400: 2.5 to 11).
  • Assay conditions and options — ethyl glucuronide is for criminal justice or forensic use only, the SARS-CoV-2 antigen assay is for CLIA-certified moderate- or high-complexity labs, MicroTip Partnership Assays go to a person to confirm availability by country, user-defined channels (20 on the XT 7600 and 5600, none listed on the XT 3400) and laboratory automation interfaces (2, or 1 on the XT 3400).
  • Site readiness — power (two dedicated 20 amp lines or one dedicated 30 amp line with UPS for the XT 7600 and 5600; one dedicated 15 amp line for the XT 3400), line voltage, room temperature (15 to 30 degrees Celsius), humidity (15 to 75 percent), altitude (up to 2,439 meters), and the total reagent positions the order states, which must equal the computed one.

Any assay addition to these three analyzers that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none are published, so this page shows no price build-up), the other 7 or so VITROS assays and every model not named here, the exact number of tests per cartridge or pack, reagent shelf life and calibration, and real-world throughput.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Three separate position limits per model, different on the XT 3400Only with care
Each assay uses a MicroSlide, MicroWell or MicroTip position depending on its technology, and the limit for each differs by model. A rules-based CPQ needs the technology of every assay and a running count per tray.		The technology, what is loaded and the packs added are summed per tray and compared with the model limit on every call.
Assay menu by model, including assays still in developmentOnly with workarounds
Which assays each model offers is a table of assay by model with a status. A rules-based CPQ needs a compatibility table or one rule per assay and model, edited whenever a menu changes.		Assay and model arrive in one request and are matched to the published menu row on every call.
Sample rules tied to the assay (urine, CSF, whole blood, amniotic fluid)Only with workarounds
The allowed sample depends on the assay, the model and, for amniotic fluid, the country, so the rules multiply quickly.		The assay, model, sample type and site are compared together, in any order.
Power, voltage and room conditions that differ by modelOnly with care
The power supply and voltage range differ for the XT 3400, and the room limits apply to every model; each is a separate rule that must see the model choice.		All site conditions are checked against the selected model on every call.
Total positions the order statesOnly with care
The stated total has to be recomputed from what is loaded and what is added, then compared.		The stated total is a field in the request, compared with the computed one on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order that adds an assay to a VITROS XT 7600, VITROS 5600 or VITROS XT 3400: the assay, the packs to add, what is already loaded in each reagent tray, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures the public VITROS brochures list and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please add 3 Glucose packs to the VITROS XT 7600. It currently holds 70 MicroSlide cartridges, 18 MicroWell packs and 12 MicroTip packs, and the lab needs 0 user-defined channels and 1 laboratory automation interface. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. The power supply does not match the specification: XT 7,600 and 5,600 need 2 dedicated 20 amp lines or 1 dedicated 30 amp line with UPS; the XT 3,400 needs 1 dedicated 15 amp line. The room temperature of 32 degrees Celsius is outside the operating range of 15 to 30 degrees. The relative humidity of 80 percent is outside the operating range of 15 to 75 percent.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for power, voltage and room conditions that differ by model, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the power supply to One dedicated 30 amp line with ups, the room temperature to 24 degrees Celsius and the relative humidity to 50 percent.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All three earlier findings are cleared, and the validator's figure matches the quote.
    13. 
      
  13. Three problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    14.
