Hi, when you said low blood levels 7.8, which one do you mean? red blood cell, platelet or else? Normal red blood cell is 4.2 to 5.4 million cells/mcL, normal range of platelet 150,000 to 400,000 platelets per microliter (mcL) or 150 to 400 × 109/L. High WBC is an indicator of bacterial infection. When the infection is cleared, you should be able to see WBC back to normal. The key is how to reduce the risk of infection.
