School of Biosciences.



Dr Huggett read genetics in Liverpool University followed by a PhD in Cardiff University where he studied the potential role of mechanically regulated genes in bone remodeling. Particularly interested in the application of advanced molecular methods to clinical scenarios he moved to UCL in 2002 to take up a Senior Research Fellow position with Professor Alimuddin Zumla. Here he investigated approaches to diagnose infectious diseases in developing world settings before moving to LGC in 2009. At LGC, which is the UK's designated national measurement institute role for chemical and bio-analytical measurement, he has led a large number of molecular diagnostics, genomics and nucleic acid research projects. This work focuses on high
 accuracy measurement as well as
 strengthening the traceability of measurements that underpin
 legislation, regulation and standardisation. In 2016 Dr Huggett joined the University of Surrey while retaining a joint appointment with LGC, where his focus is on analytical microbiology and diagnosis of infectious diseases.

Research interests

Molecular diagnosis and routes to support translation of preclinical methods to patient care. My interest are in applying the concepts of metrology (the science of measurement) to improve accuracy and reproducibility of molecular analysis and this has enabled me to investigate a wide range of fascinating subjects ranging from pathogen identification and genotyping to the detection of surrogate markers of infection. Research has investigated methodologies ranging from high throughput centralised approaches to point of care.

A potent and heat-stable tetrodotoxin (TTX) has been found to accumulate in various marine bivalve species, including Pacific oysters ( Crassostrea gigas), raising a food safety concern. While several studies on geographical occurrence of TTX have been conducted, there is a lack of knowledge about the distribution of the toxin within and between bivalves. We, therefore, measured TTX in the whole flesh, mantle, gills, labial palps, digestive gland, adductor muscle and intravalvular fluid of C. gigas using liquid chromatography-tandem mass spectrometry. Weekly monitoring during summer months revealed the highest TTX concentrations in the digestive gland (up to 242 µg/kg), significantly higher than in other oyster tissues. Intra-population variability of TTX, measured in the whole flesh of each of twenty animals, reached 46% and 32% in the two separate batches, respectively. In addition, an inter-population study was conducted to compare TTX levels at four locations within the oyster production area. TTX concentrations in the whole flesh varied significantly between some of these locations, which was unexplained by the differences in weight of flesh. This is the first study examining TTX distribution in C. gigas and the first confirmation of the preferential accumulation of TTX in oyster digestive gland.

Background The global COVID-19 pandemic has led to extensive development in many fields, including the diagnosis of COVID-19 infection by mass spectrometry. The aim of this systematic review and meta-analysis was to assess the accuracy of mass spectrometry diagnostic tests developed so far, across a wide range of biological matrices, and additionally to assess risks of bias and applicability in studies published to date. Method 23 retrospective observational cohort studies were included in the systematic review using the PRISMA-DTA framework, with a total of 2 858 COVID-19 positive participants and 2 544 controls. Risks of bias and applicability were assessed via a QUADAS-2 questionnaire. A meta-analysis was also performed focusing on sensitivity, specificity, diagnostic accuracy and Youden’s Index, in addition to assessing heterogeneity. Findings Sensitivity averaged 0.87 in the studies reviewed herein (interquartile range 0.81 - 0.96) and specificity 0.88 (interquartile range 0.82 - 0.98), with an area under the receiver operating characteristic summary curve of 0.93. By subgroup, the best diagnostic results were achieved by viral proteomic analyses of nasopharyngeal swabs and metabolomic analyses of plasma and serum. The performance of other sampling matrices (breath, sebum, saliva) was less good, indicating that these protocols are currently insufficiently mature for clinical application. Conclusions This systematic review and meta-analysis demonstrates the potential for mass spectrometry and ‘omics in achieving accurate test results for COVID-19 diagnosis, but also highlights the need for further work to optimize and harmonize practice across laboratories before these methods can be translated to clinical applications.
