However, many factors may affect the accuracy of the measurements, mainly pre‐analytical variables such as sample type and interfering factors.[3] The type of blood samples (plasma or serum) or collecting tube (plain or clot‐activating tube) sent from the hospital wards to the laboratory may vary, depending on the tests requested for the patient. The question of this study was whether the amounts of 25(OH) D3 measured by the HPLC method in serum (prepared in tubes containing gel and clot activator) and plasma are the same. For this purpose, blood samples from eight patients were collected simultaneously in tubes containing gel and clot activator, and in tubes containing EDTA (without gel). All tubes were centrifuged for 10 min at 3000 × g.
