Can blood donations influence the result?

Anyone who regularly donates blood, of course, needs a balanced nutrient ratio in order to compensate for the blood loss. For example, there are vitamins such as B12, folic acid or B6 and minerals such as iron which are important for blood formation. Lack of these nutrients cannot adequately balance the blood loss. However, there is a study showing that a blood donation has no influence on these values. This is due to the fact that the blood loss is too low to have an effect. In addition, researchers believe that regular donations increase awareness of a healthy diet, minimising the risk of deficiencies. Nonetheless, researchers suggest that periodically testing vitamin status as the trend of high-calorie and low-vitamin food increases the risk of deficiencies. However, the study situation on this topic is still very thin, which is why no clear statements are feasible.To compensate for any deficiencies caused by a blood donation we recommend either consuming more nutrient-rich foods or taking appropriate supplements. In conclusion, it can be said that the donation should not have any influence on the measurement result. However, it is advisable to regularly check your blood levels to detect possible deficiencies early and to counteract them.
