About Bio

Customer Focus

Established in 1979, Bio-Diagnostics is a niche bio-tech business located in Upton-upon-Severn, Worcestershire, 40 miles south west of Birmingham. Bio-Diagnostics is the longest established Autoimmune company in the UK.

Bio-Diagnostics has consistently committed itself to provide reliable support to our customers. Having initially focused on autoimmune disease, Bio-Diagnostics now has 3 divisions Immunology, Immunohistochemistry and Dermatology, including allergy. Bio-Diagnostics are the market leader in providing solutions for Contact Dermatitis testing in the UK. All areas are complemented by seminars, workshops, and a high level of technical expertise. We are also able to offer training and workshops at our laboratory in Worcestershire or at your own site. We offer a superior level of friendly customer service and maintain high quality as standard.


The Family Bio-Tech

We remain a family owned business with individual staff gaining over 30 years’ experience working with us as we have grown. We pride ourselves in having successfully supported some accounts continuously since we first began, having originally helped by working together, assisting with the original setting up of many UK departments, and subsequentially having provided many years of training for new staff, as well as those original individuals, of whom many remain today. We are fully committed to maintaining this skill and standard by continuing to provide training and support to customers, by sharing our expertise with them and their new staff on an ongoing basis well into the future.

As well as in-house manufacture we work alongside select partners with high quality medical diagnostic, and ancillary products to promote to the medical laboratories, clinics, and facilities within the UK and beyond.

Beyond the Quality Standard

The company holds a Wholesale Distribution Authorisation, issued by the MHRA , which enables us to import and distribute specialist products such as patch test allergens, skin prick test allergens and allergy vaccines. As one of the only UK companies still operating a private immunology laboratory in our field, the company participates in UK NEQAS and maintains membership of organisations such as the IBMS, BIVDA and the UK Chamber of Commerce.

Our own highly efficient and flexible operation within our UK manufacturing plant is able to fulfill large or small orders, and can assist SME’s with regulatory affairs for contract development and manufacture if required. Packaging and laboratory facilities are available for both original equipment manufacturer (OEM) and proprietary products.

I found Bio-diagnostics more than helpful, replacing all our allergens in a very quick and efficient way, reducing the complexity of ordering and providing an excellent service to us.

The company and individual staff are very attentive and efficient at responding to our needs. I would not hesitate in recommending Bio-diagnostics to provide a solution for any potential customers. Thanks Bio-diagnostics.
