Vitamins, metabolic markers and genotypes (SNPs) offered by BEVITAL, organized according to the analytical platform.

Multianalyte determination is carried out in a single aliquot which reduces sample volume requirement. For detailed recommondation on blood sampling, sample volume, transportation etc. related to specific parameters, go to "Metabolites and vitamins".

Some metabolites are measured by two or more methods, but against the same calibrators. This increases accuracy and precision, minimizes the possibility of assay interference and ensures adequate sample handling and logistics. The table to the left shows the metabolites available at more than one platform.
