(a) Similarities between the “F” and “$” codes. (b) Possible combinations of the −/+ and $/F barcodes. One analyte is tested with the +/− (Test 1, blue bracket) characters, another one with the F/$ (Test 2, green bracket) characters. Additional analytes require further extension of the barcode using the same −/+, $/F codes or others. (c) Reading of the combined barcode for “+$” with a free app.
