Estimate of intake of benzoic acid in the Belgian adult population.
chromatography (HPLC) method, optimized and validated for this purpose. Individual food-consumption data were then multiplied with the actual average concentrations of benzoic acid per food group (Tier 3). Usual ...
Validation of a liquid chromatography-mass spectrometric assay for tacrolimus in peripheral blood mononuclear cells.
validated in the range of 0.01-5 ng/mL. Limit of detection and of quantification are 0.005 and 0.01 ng/mL, respectively. Intra-assay and interassay recoveries ranged from 89.2% to 114.3% and 85.3% to 103.9%, ...
Comparison of concentrations of mercury in ambient air to its accumulation by leafy vegetables: an important step in terrestrial food chain analysis.
useful for biomonitoring purposes. A comparison made in the 1980s between biomonitoring results with grass and the mercury concentration in leafy vegetables from private gardens nearby proved to be valid ...
NUSAP method for evaluating the data quality in a quantitative microbial risk assessment model for Salmonella in the pork production chain.
(proxy, empirical basis, method, and validation) to assess the quality, and this was graphically represented by means of kite diagrams. The parameters obtained significantly lower scores for the validation ...
Optimization and validation of a liquid chromatography tandem mass spectrometry (LC/MSn) method for analysis of corticosteroids in bovine liver: evaluation of Keyhole Limpet beta-glucuronidase/sulfatase enzyme extract.
Mass Spectrometry VALIDATION Abstract: A liquid chromatography tandem mass spectrometry (LC / MS (n)) method for the determination of 12 corticosteroids in bovine liver has been optimized and validated ...
The gap between food-based dietary guidelines and usual food consumption in Belgium, 2004.
was collected with two non-consecutive 24 h recalls, using the validated software package EPIC- SOFT in combination with a self-administered FFQ. Habitual food intake was estimated by the Nusser method. ...
Comparison of classical serotyping and PremiTest assay for routine identification of common Salmonella enterica serovars.
that the system has been validated beforehand with a significant number of strains originating from that particular area. Health Topics: Animal health Category: A1 FOS Classification: 4.03 Veterinary ...

Indirect foot-and-mouth disease vaccine potency testing based on a serological alternative.
at least as precise (repeatability=65.8%, reproducibility=60.7%) as the in vivo test, can be standardised and results in a quantitative PD50 value. The validity of the procedure was also demonstrated. ...
The importance of quality assurance/quality control of diagnostics to increase the confidence in global foot-and-mouth disease control.
diagnostics. A quality assurance (QA) system is deemed essential for laboratories involved in certifying absence of FMDV or antibodies against the virus. Therefore, laboratories are encouraged to validate their ...
