I'm really worried because my monocytes are still absent in my latest CBC results, just like last summer. The only weird thing in the test is that there's no monocytes. My report shows Neutrophils at 50, Lymphocytes at 49, Monocytes at 0, and Eosinophils at 1. Should I be concerned about monocytes being zero? It's making me quite anxious. What could this mean?
