Understanding Your Results
Results show counts and percentages for each cell type compared to reference ranges. Low red cells or hemoglobin may indicate anemia, while high white cells often suggest infection or inflammation. The differential helps pinpoint whether an immune response is bacterial, viral, allergic, or parasitic in nature.
