13.2. Operating principle

The Bloom Lab is an electronic device, which contains an optical measurement system (optical reader) to quantify the test
line intensities produced by the Bloom Test strip during use. It captures the Bloom Test strip read-out window, automatically
detects the test and control line and calculates the mean intensity value for each line by image analysis. This mean value,
in connection with further image analysis, corresponds to the concentration of the captured target analyte. The actual
concentration of the target analyte is calculated diff erently for each batch of Bloom Tests using the Bloom App, thus enabling
measurements with the Bloom Lab for a wide variety of analytes.
