A result you can read by eye.
Lateral-flow cassettes and strips that need no reader, no power and no cold chain. A drop of whole blood, serum, plasma or urine, and a line to read a few minutes later — in a clinic, a ward, a pharmacy or the field.
Read by eye, or read by an instrument.
Qualitative, visual
A line appears or it does not. No instrument, no calibration, no power. Suited to screening and to settings without a laboratory.
Quantitative, instrument-read
The SHD R2D2 fluorescence readers give a number, not a line, and send it to the laboratory system. Suited to triage and to monitoring.
Both from SHD
The same marker is often available in both formats, so a network can screen in the field and quantify in the clinic without changing supplier.
