Reticulozytäre

Reticulozytäre refers to something related to reticulocytes. Reticulocytes are immature red blood cells, meaning they are developing red blood cells that have recently been released from the bone marrow into the bloodstream. They are larger than mature red blood cells and still contain remnants of ribosomal RNA, which gives them their characteristic reticular or network-like appearance when stained with specific dyes. This network is the reason for their name.

The presence and number of reticulocytes in the blood are important indicators of the bone marrow's ability to produce red blood cells. A high reticulocyte count, known as reticulocytosis, generally suggests that the bone marrow is actively producing red blood cells, often in response to blood loss (hemorrhage) or the destruction of red blood cells (hemolysis). It can also be a sign of successful treatment for certain types of anemia, where the bone marrow is stimulated to produce more red blood cells. Conversely, a low reticulocyte count can indicate that the bone marrow is not producing enough red blood cells, which might be due to bone marrow failure, certain chronic diseases, or nutritional deficiencies like iron or vitamin B12 deficiency.

Therefore, assessing the reticulocyte count is a standard part of a complete blood count (CBC) and is crucial for diagnosing and monitoring various hematological conditions. The term "reticulozytäre" would be used in a medical or scientific context to describe findings, measurements, or processes related to these immature red blood cells. For instance, one might discuss "reticulozytäre Aktivität" to refer to the bone marrow's red blood cell production rate as indicated by reticulocyte levels.
