Influence of delayed sample processing on blood immune cell phenotypes, immune cell responses and serum anti-influenza vaccine antibody titres

Provision of blood from distant research partners to a central laboratory can result in delayed blood processing prior to assessment of immune parameters. It is important to evaluate the effect of such delays on immune parameters. This study investigated the effect of storage of blood at room temperature for up to 72 h prior to processing and analysis on a range of immune parameters. Blood was collected from 10 healthy participants and analysed...
