In a collaboration project between MedUni Wien Biobank, Biobank Graz and researchers from several clinical departments of the Medical Universities of Graz and Vienna, short-term and long-term storage stabilities of SARS-CoV-2 antibodies were evaluated using samples from Biobanks Graz COVID-19 Convalescent Cohort the Biobank's SARS-CoV-2 cohorts.
Moreover, the authors highlighted the problems with evaluating long-term storage effects, as the evaluation tool (the analytical test itself) also changes over time, which introduces additional analytical imprecision and leads to overestimation of the pre-analytical variability.
