BEVITAL AS

Stability curves

This page provides data on pre-analytical stability during storage and freezing/thawing of most biomarkers or metabolites included in the repertoire of BEVITAL by April 2019.

BEVITAL platforms A – H

E: LC-MS/MS

Folate species and catabolites.

F: Microbiological assay

Folate (B9) and cobalamin (B12).

H: LC-MS/MS

Lipid-soluble vitamins and long-chain acylcarnitines.
Amino- and carboxylic acids.

The panels (click on biomarkers above) show the stability of all biomarkers in EDTA plasma and serum at room temperature (left) for the indicated duration and after increasing number of freeze-thaw cycles (right). The white zone indicates +/- 15% deviation from the average of the first three time points for plasma. Data are given as geometric mean with standard error (SE) for samples from 15 healthy subjects.

Choline derivatives. Charged, methylated or sulfur amino acids. Short- and medium-chain acylcarnitines.

The panels (click on biomarkers above) show the stability of all biomarkers in EDTA plasma and serum at room temperature (left) for the indicated duration and after increasing number of freeze-thaw cycles (right). The white zone indicates +/- 15% deviation from the average of the first three time points for plasma. Data are given as geometric mean with standard error (SE) for samples from 15 healthy subjects.

Kynurenine pathway and B vitamins (B1, B2, B3, B6).
