FDA Product Code LIP: Enzyme Linked Immunoabsorption Assay, Treponema Pallidum

Syphilis serology is a core component of STI screening. FDA product code LIP covers enzyme-linked immunosorbent assay systems for Treponema pallidum antibody detection.

These treponemal immunoassays detect IgG and IgM antibodies specific to Treponema pallidum antigens for the screening and diagnosis of syphilis. Modern EIA-based treponemal tests are increasingly used as first-line syphilis screening tests.

LIP devices are Class II medical devices, regulated under 21 CFR 866.3830 and reviewed by the FDA Microbiology panel.
