Official basis (Guidance): Use the substrate-specific sequence and controls in the UK Fingermark Visualisation Manual. Treat national operational guidance as jurisdiction-specific.
Procurement note: Manual landing-page verification is not a checked recipe. Final solvents, development conditions and ancillary reagents must come from the controlled FVM process.
