Countable Labs announced the launch of the RNA Module for Countable PCR. This new solution brings direct counting of RNA to the Countable PCR platform, enabling one-step, bias-free RNA quantification.

Countable PCR is a highly scalable PCR technology leveraging single-molecule isolation across 30 million compartments per experiment to achieve true single-molecule quantification from a simple PCR workflow. The technology facilitates the identification of rare events as low as 0.004% variant allele frequency (VAF), even with small sample inputs. 

The RNA Module for Countable PCR simplifies the workflow for RNA samples by eliminating the need for cDNA generation prior to Countable PCR, allowing users to directly load RNA for one-step reverse transcription and amplification, enabling accurate RNA quantification with lower variability. This technology enables the rapid detection of fusion transcripts, pathogens, as well as the accurate quantification of RNA viral load, minimal residual disease (MRD), and other RNA molecules of interest. Countable PCR with the RNA module delivers absolute RNA quantification with a broad dynamic range (1 to 1 million target molecules per reaction), sensitivity for viral RNA down to 0.001%, and minimal variability. 

To assist customers in building experiments for Countable Labs’ systems, the company launched a new Community Assays portal. This portal is designed to accelerate Countable PCR adoption by enabling customers to access pre-designed and pre-verified assays for different applications.

Countable Labs will discuss its one-step RNA fusion quantification solution for MRD monitoring with Countable PCR at a webinar on December 11, 2025. 

Countable Labs will be exhibiting at AMP, showcasing its recently launched Countable PCR instrument in booth #228. In addition, the company will participate in a workshop with Promega and present four posters.
