Since we moved location, we are having intermittent issues with the paper printing of laboratory reports. We are working with our IT team to resolve this and will update once resolved. Please bear with us and telephone (0203 448 3818) if the results are needed urgently.
Please consider signing up for secure auto e-mail of laboratory reports.
To sign up for secure auto-emailing of lab reports, please e-mail uclh.enquiry.neurometabolic@nhs.net the following:
- A generic laboratory e-mail that is regularly checked for reports to be e-mailed to, preferably nhs.net.
- Neurometabolic unit laboratory number of a previous report so we can check the source code we have on record for your lab.

We are evaluating a new lot number of one of our complex I enzyme reagents and must performed a more detailed evaluation.
Consequently, this will impact on our turn around time for the muscle respiratory chain enzyme service. Our other mitochondrial respiratory chain enzyme (complex II+III and IV) are not affected.
We will continue to update you. If you have any particular concerns or questions, please don’t
hesitate to contact.
The Neurometabolic Unit is a highly specialised UKAS accredited medical laboratory No 8341 based at Queen Square. It provides a unique range of investigations and clinical laboratory advice encompassing mitochondrial, neurotransmitter, pterin and amino acid disorders. Set up in 1995, it has evolved from an academic translational research laboratory to becoming a UKAS accredited clinical laboratory service, which also provides the pathology specimen reception for National Hospital for Neurology and Neurosurgery (NHNN).
The activities of the Unit support many groups within NHNN and the wider activities of UCLH Trust. In particular, the laboratory has close clinical associations with colleagues within the Movement Disorders, Neuromuscular, Neurogenetic services and the Charles Dent Metabolic and Intensive Care Units.
On-going research programmes supplement and enhance the service provision with close collaborations with academic colleagues at UCL Queen Square Institute of Neurology and UCL Great Ormond Street Institute of Child Health.
In the genomics era, the laboratory is well placed to develop specialist testing required to elucidate the pathogenesis of genetic variants of uncertain significance. We can leverage our technical expertise in enzyme kinetics, HPLC and mass spectrometry to develop assays for research studies and with our clinical laboratory acumen, continue assay validation to develop UKAS accredited clinical laboratory services thus facilitating the bench to bedside approach to laboratory medicine.
The laboratory has close collaborations with other specialist laboratories at NHNN and in the Queen Square area. Several members of staff have honorary or joint appointments with the Dept. of Chemical Pathology at Great Ormond Street Hospital (GOSH).
The diagnostic mitochondrial biochemistry laboratory service for the NHS Rare Mitochondrial Disorders Service in London is hosted by the Neurometabolic Unit, providing mitochondrial respiratory chain enzymes (MRCE) and mitochondrial ATP Synthase (complex V) testing in tissue biopsies.
The NeurometabolicUnit is also the only laboratory in the UK to provide an accredited clinical biochemistry service for the diagnosis and monitoring of inherited neurotransmitter disorders through analysis of monoamine, pterin and other associated metabolites in CSF.
Our user manual provides contact details for the laboratory, sample requirements, a list of full current test reportoire, methodology, and reporting times. For test prices, please contact Service manager.
