Established in 1971, Lab M initially manufactured pre-poured media for clinical laboratories in London and the North West of England — and its name, London Analytical and Bacteriological Media, reflects its origins.

During the 1970s, the company developed its own dehydrated culture media, and by the early 1980s had added consumables and diagnostics to its product list. At that time Lab M was the only UK supplier offering such a range, and with a growing reputation for quality it soon became the ideal supplier for medium-sized industrial laboratories.

International Diagnostics Group plc (IDG) took ownership of Lab M in 1995; since then business has continued to flourish, with Lab M consolidating its position as an innovative producer of reliable, high quality microbiology products. Lab M has long enjoyed an international reputation for the high quality of its dehydrated culture media, particularly for the culture and isolation of anaerobes.

Lab M's R&D group is dedicated to developing innovative products and processes for the food, industrial, clinical and waste/wastewater testing sectors.

Lab M is certified in accordance with ISO 9001:2000 and ISO 13485; products for the clinical market are supplied in compliance with the European IVD directive and carry the CE mark.
