It's not a lymph it's a specialised cell called nurse cells which not only create Red blood cells but after 20-30 days when that red blood cell is worn out another nurse cell recycles it.
Yes, it is lympahtci tissue but is recycles RBCs and stores many RBCs in case of a massive blood loss.

The spleen is an organ that stores and destroys red blood cells (RBCs) and produces agranulocytes, such as lymphocytes and monocytes. It plays a critical role in filtering the blood and removing old or damaged blood cells.
low rbcs count shows anaemia high rbcs count show polycythemia vera. rbcs enumerations shows the bonemarrow how much active.
Hematocrit measures the volumeof packed RBCs as a percentage of blood volume.
If red blood cells (RBCs) are mixed with a saline solution, the RBCs may undergo hemolysis, where they rupture and release their contents into the solution. This can lead to changes in the osmotic balance and potentially cause damage to the RBCs. It is important to handle RBCs carefully to prevent hemolysis and maintain their function.
