Molecular diagnostics for TB and related infections

Multiplex molecular diagnostics built for practical deployment.

Papyrus Diagnostics develops molecular diagnostic platforms for tuberculosis and related infections. Its lead system, Papyrus MutaCheck Pro, combines identity and drug-resistance detection in a single workflow using existing PCR infrastructure.

Papyrus MutaCheck Pro workflow

Built to close the gap between molecular insight and routine use.

Molecular diagnostics can generate high-value clinical information, but many workflows remain expensive, fragmented, or difficult to deploy in routine settings. Papyrus is building systems that make advanced molecular testing more practical without requiring new dedicated infrastructure.

Papyrus MutaCheck Pro

A consumables-led molecular diagnostic platform for tuberculosis identification and drug-resistance detection.

Designed to distinguish Mycobacterium tuberculosis from non-tuberculous mycobacteria and detect key drug-resistance mutations in one workflow. Amplification is performed on existing PCR blocks, and results are read using a proprietary closed-tube strip and compact reader.

One workflow. Existing PCR systems. Actionable results.

Why it matters

Faster answers

Combines identity and resistance-linked information in a single test workflow.

Lower infrastructure burden

Works with existing PCR systems and avoids the need for a new dedicated molecular instrument.

Cleaner operation

Uses a closed-tube strip format to reduce post-PCR handling and lower contamination risk.

From amplification to mutation calling

Papyrus diagnostic architecture

A modular diagnostics platform with integrated systems and standalone components.

Primary product

Papyrus MutaCheck Pro

Lead molecular diagnostics system for tuberculosis and resistance-linked detection.

Flagship application
Commercialized product

DetectFlow

Nucleic acid lateral flow detection platform for molecular readout.

Commercialized product

DetectGold

Gold nanoparticle reagent system for diagnostic signal generation.

Expansion path

Papyrus ImmunoCheck

An extension of the Papyrus platform for antigen and antibody-based testing.

A platform, not a one-product company

MutaCheck Pro is the first integrated application of the Papyrus platform. DetectFlow and DetectGold represent commercialized enabling products within the same stack, while ImmunoCheck extends the platform into adjacent diagnostic formats.

Reusable chemistry
Scalable workflow logic
Extendable readout architecture

Validation

In a blinded feasibility study at NIRT Chennai, Papyrus MutaCheck Pro showed strong early performance for tuberculosis detection and rifampicin resistance detection, supporting further validation.
