Method, apparatus, and computer program product are provided for anonymized diagnosis using lateral flow assays. In some embodiments, a test card includes one or more lateral flow assay (LFA) with one or more test patterns (e.g., full line, partial line, dot), one or more dummy patterns, and one or more control patterns. To visually encode LFA results, at manufacture, one or more lines/dots containing true results of the LFA(s) each has a position mixed with other "dummy" lines/dots, in randomized position patterns selected from among a plurality of possible position patterns. An optical machine-readable representation of data (e.g., QR code) is attached to the test card and encodes test card identification information (e.g., lot number, serial number, test type) associated with the test card. In some embodiments, a passcode card having a scrapeable coating that conceals a passcode associated with the test card is removably attached to the test card.
