🧩 Results Data // .pdf

In a previous article, we introduced the different types of results data🔗 the Delvotest® Accelerator Smart (DAS) generates during and after testing, and how to access them. One of these is an easy-to-read .pdf (Portable Document Format) file report containing the final plate table's results (including Z-values) and high-level, critical metadata (e.g., operator, temperature, etc.). In this article, we explore this report file in depth.

Access and Structure

To access one of these .pdf reports, simply follow the steps outlined in Introducing Results🔗. Once you have the file, you should see something like this:

If you'd like to get this example file, here's a download link🔗. // add link

Similar to the Incubation tab🔗, the report is divided in two main sections: at the top, a Summary Data Section textually outlining critical, overarching information about the test; and, at the bottom, a final, data-enriched Plate Table Section reflecting the Incubation tab's Plate table subsection🔗.

Summary Data Section

This section typically contains fourteen report fields. Here's what each means, and, when relevant, where you can find more information about them.

Measurement Name
The unique identifier which follows its respective Test subfolder's name and its naming convention🔗.

Device Name
The DAS's which executed the test's name, which you can view and edit🔗in the Set up tab.

Operator
The name of the operator selected when preparing the test🔗 in the Incubation tab's Operator dropdown field🔗.
Your list of operators is also available for you to view and edit🔗in the Set up tab.

Date
The date when the test started, defined according to this DAS's customisable localisation settings🔗. It is formatted with hyphen ('-') delimiters between its year (four digits), month (two digits), and day (two digits) values.
∴ YYYY-MM-DD
e.g., for 5 December 2024, the result should be 2024-12-05.

Product
The test line of your Delvotest® plate, as automatically identified by the DAS when preparing the test🔗 in the Incubation tab's Product name field🔗.

Start time
The time the test started, defined according to this DAS's customisable localisation settings🔗. It's formatted using a 24-hour clock, with colon (':') delimiters between its hour (two digits), minute (two digits), and seconds (two digits) values.
∴ HH:MM:SS
e.g., for 11:55:22 (AM), the result should be 11:55:22.

Batch Number
The data identified either during automatic barcode scanning or manual barcode input🔗 when preparing the test in the Incubation tab's Batch number field🔗.

Plate Number
The data identified either during automatic barcode scanning or manual barcode input🔗 when preparing the test in the Incubation tab's Plate number field🔗.

Method
The data selected when preparing the test in the Incubation tab's Inhibitor method dropdown field🔗.

Incubation time
The total time taken for the plate's incubation—which, based on the DAS's Working Principle🔗 is incidentally also the plate's Control Time🔗. It's formatted with colon (':') delimiters between its hour (two digits), minute (two digits), and seconds (two digits) values.
∴ HH:MM:SS
e.g., for a test that took 3 hours, 19 minutes and 4 seconds, the result should be 03:19:04.

Comments
The data entered when preparing the test🔗 in the Incubation tab's Comments field🔗.

Comments After
// ask @Atha — where/when are they able to add comments afterwards? //

Warnings
Whenever the DAS detects abnormal performance, like in this example, it will textually describe the issue(s) in this section of the report. There are a series of potential outcomes, which we explore as a troubleshooting centre in Introducing Results Warnings🔗.

Temperature [mean / min / max]
Every minute during testing, the DAS captures temperature data, where, in this field of the report, the overall median, minimum and maximum values are summarised.

Plate Table Section

This section reflects the Incubation tab's Plate table subsection🔗. Every plate-well contains the following data:

Colour coding
Every plate-well's NEGATIVE and POSITIVE results are, respectively, colour-coded in green and red. In circumstances where no result is established for a plate-well — e.g., due to an error during testing, or when only a/some plate-strip(s) are tested —, this will be colour-coded in grey.

Nref and Pref
For plate-wells where either a NEGATIVE or POSITIVE reference control was denoted when preparing the test🔗 in the Incubation tab's Negative and Positive checkboxes🔗, this information will be reflected here in the report. // need to check if cell-level comments are also displayed ... should've tested, sorry! //

💡By the way, did you know that even if you indicate a sample is a reference control, the DAS will still test it without presuming its performance prior? This is part of the DAS's way of ensuring continuous verification for your reference controls as part of its Working Principle🔗.

Z-values
Based on the DAS's Working Principle🔗, every plate-well cell also reports its final Z-scale value as determined at Control Time🔗, within one decimal point. // add link

File Naming Convention

Particularly helpful for automating reporting functions when integrating DAS data flows with your systems e.g., Laboratory Information Management System (LIMS), this report file follows a standard naming convention:

[Device Name]_[Batch Number]_[Plate Number]_[Date]-[Time]_[???]_Results.pdf

[Device Name]
The DAS's which executed the test's name, a parameter you can view and edit🔗in the Set up tab.
