What we do
At Global Lab eXpert Group (GLXG) our goal is to support doctors, practitioners and patients around the world in finding the best and most appropriate testing to guide patients on their personal health journeys.
Our business was born from the experience of those who founded it. Whilst our core focus is providing access to rigorously validated and reliable testing that gives doctors and patients the results they need, our mission is to simplify the complexity of diagnostic choice, helping practitioners and patients find the most effective path forward.
We provide access to advanced diagnostics, from cellular health and burnout including hormonal imbalances and environmental toxins, through to molecular genetics and the latest DNA sequencing. Our lab is also an expert in leading T Cell/iSpot methodology for complex diseases and chronic bacterial and viral infections including commonly associated health conditions.
We are a passionate team, dedicated to answering the questions that many struggle to obtain within their local healthcare systems. With tools, experts, and specialist partnerships with a world-class laboratory, we aim to identify, source, and deliver the highest-quality diagnostic testing.
Our Customer Service and Operations team is a mix of different nationalities, multi-lingual and located around Europe. With hubs in the UK, Europe, Dubai and North America, we deliver tests to patients around the world.

Why choose us?
We prioritise diagnostic excellence, not just speed and convenience. That’s why we’ve partnered with Labor Susa (Susa Lab)* a government certified laboratory in Germany known for its advanced scientific testing, flexibility, and in depth analysis.
Unlike large commercial labs, Labor Susa is privately owned and purposefully small, allowing for a more agile, focused approach to complex diagnostics. Using the latest diagnostic machines including the Illumina MiSeq Dx sequencer (for genetic microbiome diagnostics and research), the ICP-MS from Agilent (for all metal testing) and the GC-MS from the company Shimadzu (for Omega 3/6 fatty acids and microplastics) owner, Dr Milorad Susa, also collaborates with specialist research institutions and universities. Using this technology and insight, GLXG partners with Dr Susa to create bespoke test panels informed by the latest science, not commercial demand.
GLXG also works with sector specialists from areas such as; Endocrinology, Fertility, Gut Health, Long COVID, CFS/Fibromyalgia, Lyme & Infectious Diseases, Longevity, Health & Wellbeing, Alzeimers and many more to provide post-testing support to practitioners and patients alike.
With GLXG and Labor Susa, you’re not simply accessing a test, you’re connecting to a smarter, more holistic diagnostic process.

Recently I have been struggling a lot and getting the tests done became more stressful than I’d hoped. However, Daniela who I’d been communicating with helped me so much throughout the process to make sure I could get them done successfully- she was calm, kind, responsive and reassuring.
I also know that GLXG has given me more detailed information on my illness than any other medical experience in the UK (regarding Lyme disease, chronic fatigue, long covid) and would highly recommend them to anyone struggling with the same illness.

Following close to two years of working my way through, what I believed at the time to be, symptoms relating to long-COVID, a friend in a similar position to myself suggested that I get in contact with GLXG.
Previous testing for tick diseases in the UK resulted in a negative NHS result. However, following a really informative free consultation with both Aaron and Bronia, my updated blood tests returned positive results for multiple tick-borne diseases through the GLXG-Susa Lab specialised T Cell / iSpot tests.
GLXG was extremely helpful in recommending a clinic that specialised in treating tick-borne diseases, with whom I have had a very in-depth initial consultation which has helped inform the first steps of a treatment/recovery programme.
I would thoroughly recommend GLXG to anyone wanting to find help and receive information on the most appropriate testing to help improve their health, especially when lots of other avenues have been explored – thank you!

Despite being a medic at the forefront of the post COVID treatment space, I could not get to the bottom of my ongoing health issues. That is – until some colleagues suggested using GLXG through a private specialist on the continent.
The testing for tick diseases in the U.K. is not as advanced as on the continent and my previous negative NHS tests turned out (for me anyway) to be positive through the GLXG-Susa Lab specialised T Cell / iSpot tests.
Now I have some answers but have hope through my specialist that there will be some improvement or even recovery.
