About Bioventix plc:

suitable reagent. Bioventix currently offers a portfolio of antibodies to
customers for both commercial use and R&D purposes, for the diagnosis or
monitoring of a broad range of conditions, including heart disease, cancer,
fertility, thyroid function and drug abuse. Bioventix currently supplies

diagnostics companies. Bioventix is based in Farnham, UK and its shares are
