About Us

About Us

Izi-Cornerstone is a Multipurpose Laboratory, Licensed and Certified by the Medical Laboratory Science Council of Nigeria and the Nigerian Corporate Affairs Commission.

We started business in Lagos, Nigeria in 1998. With over 20 years’ experience, we have painstakingly built a strong, invaluable reputation amongst corporate bodies, health practitioners and the general public. When the need is to precisely ascertain the nature/condition of one’s health status, IZI-Cornerstone is the first choice — our results are rapid, reliable and accurate.

IZI-Cornerstone has handled diagnostic jobs for corporate bodies such as Nestlé Nigeria PLC, SmithKline Beecham Nig. PLC, and Procter & Gamble Nig. PLC. We also had a seven-year contract managing Unilever Nig. Plc.’s factory laboratory at Agbara, Ogun State.

We recently launched our in-house, state-of-the-art Hormonal Assay Department using an ELISA Immunoassay Microplate Reader & Washer.

This has adequately met the diagnostic/research needs of the academia around us — final-year and postgraduate students from institutions such as Crawford University, Lagos State University, and Covenant University carry out their thesis work using our ELISA Immunoassay machines.
