Belgian recommendations for analytical verification and validation of immunohistochemical tests in laboratories of anatomic pathology
performance characteristics to be evaluated, (iii) the objective acceptance criteria, (iv) the evaluation method for the obtained results and (v) how and when to revalidate. A literature study and a risk ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV.
available to the Belgian population, a method was developed for screening of 17 cannabinoids and to quantify the major cannabinoids such as CBD, CBDA, ∆9- THC and ∆9- THCA. The latter was fully validated ...
Occurrence of microcystin congeners in surface waters and food in Belgium as a source of exposure to humans
group worldwide, the microcystin congeners (MC s). After method validation, the quantitative UHPLC- MS / MS approaches were applied to Belgian samples to characterize potential human exposure sources in ...
COMBINATION OF CHEMOMETRICS AND MULTIDIMENSIONAL FINGERPRINTING FOR DETECTION OF REGULATED PLANTS IN PLANT FOOD SUPPLEMENTS
concerns, necessitating an efficient screening approach for detection of the regulated plants in plant food supplements. This study aims at developing a chemometric approach coupled with fingerprinting for ...
The analysis of cannabinoids in e-cigarette liquids using LC-HRAM-MS and LC-UV
a method was developed for screening of 17 cannabinoids and to quantify the major cannabinoids such as CBD, CBDA, ∆9- THC and ∆9- THCA. The latter was fully validated using the ‘total error’ approach, ...
Using random-forest multiple imputation to address bias of self-reported anthropometric measures, hypertension and hypercholesterolemia in the Belgian health interview survey
height, weight, hypertension and hypercholesterolemia and to identify an adequate approach for valid measurement error correction. METHODS: Nine thousand four hundred thirty-nine participants of the 2018 ...
Development of a Droplet Digital PCR to Monitor SARS-CoV-2 Omicron Variant BA.2 in Wastewater Samples
used as a complementary method to other SARS-CoV-2 surveillance systems. It allows the emergence and spread of infections and SARS-CoV-2 variants to be monitored in time and place. This study presents an ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
had only rarely been associated with human cases of an outbreak, let alone during a real outbreak. Therefore, this PhD centered on the development of shotgun metagenomics methods to study ...
Development of a Taxon-Specific Real-Time Polymerase Chain Reaction Method to Detect Trichoderma reesei Contaminations in Fermentation Products
food industry to produce fermentation products, a novel real-time PCR method specific to this fungal species was developed and validated in this study to reinforce the GMM detection strategy. Designed to ...
Simultaneous Detection and Quantification of Aflatoxin M1, Eight Microcystin Congeners and Nodularin in Dairy Milk by LC-MS/MS
and sensitive LC- MS / MS method was developed and validated for the quantification of multiple cyanotoxins (microcystin congeners and nodularin) and AFM1 by the main analytical guidelines. Toxins are ...
