Part of the TAAG technology pillar, along with artificial intelligence in microbiology.
The problem: interpreting a curve isn't as simple as it looks
The raw result of a real-time PCR reaction is a fluorescence curve that rises as the target genetic material is amplified. Deciding whether that curve represents a positive, negative or inconclusive result involves evaluating the cycle at which it crossed a given threshold, the shape of the curve and, in multiplex assays, distinguishing signals from different color channels simultaneously. Doing this manually, assay by assay, is slow and opens the door to variability between analysts.
What is TxA?
TxA is TAAG's software that automates that interpretation: it analyzes the amplification curve (or melting curve, depending on the kit's technology) generated by the PCR instrument and automatically determines whether the result is positive or negative for each target analyzed, according to the technical documentation of the Ampliora, Elevia and Specio kit lines.
Why automatic interpretation matters
Consistency across analysts and shifts
An interpretation criterion applied automatically and in a standardized way reduces the variability that manual reading by different analysts or work shifts can introduce.
Speed in high-volume laboratories
In laboratories processing hundreds of samples per day, automating interpretation reduces the time between when the PCR instrument finishes its run and when the result is available for a product release decision.
Part of a broader trend: laboratory digitalization
TxA fits within a larger trend in industrial microbiology: moving results management from spreadsheets and manual readings toward integrated digital systems that connect the laboratory instrument directly to the final report, reducing manual transcription points where errors can be introduced.
Conclusion
Much of the value of a fast PCR kit is lost if interpreting the result remains a slow, manual process. TxA resolves that final stretch of the workflow, connecting the signal generated by the instrument directly to an interpreted result.

Frequently asked questions
Does TxA replace the laboratory analyst?
No; it automates the interpretation of the fluorescence curve, but the analyst remains responsible for running the assay and for the overall validation of the process.
Does TxA work with any PCR instrument?
It is designed to integrate with TAAG's kits (Ampliora, Elevia, Specio); compatibility with other providers' equipment and workflows must be confirmed directly with TAAG.
What does a laboratory gain by automating result interpretation?
Greater consistency across analysts and shifts, and less time between the end of the PCR run and the availability of the final result.
