Case Study: Laboratory test results
| White blood cell (WBC) count | 3.7 x 109/L | 4.4 - 11.3 x 109/L |
| Red blood cell (RBC) count | 5.6 x 1012/L | 4.1 - 5.1 x 1012/L |
| Hemoglobin (Hb) | 10.5 g/dL | 12.3 - 15.3 g/dL |
| Hematocrit (HCT) | 36.6% | 35.9 - 44.6% |
| MCV | 65.8 fL | 80.0 - 96.0 fL |
| MCH | 19.9 pg | 27.5 - 33.2 pg |
| MCHC | 26.7% | 33.4 - 35.5% |
| RDW | 14.0 | <14.5 |
| Platelets | 249.0 x 109/L | 100.0 - 450.0 x 109/L |
| Total serum iron | 165 µg/dL | 60 - 150 µg/dL |
| Iron-binding capacity | 230 µg/dL | 250 - 400 µg/dL |
The RBC count is increased for the amount of hemoglobin present. The concentration of hemoglobin in the RBCs is slightly decreased (hypochromic) and the cells are small (microcytic). The variation in RBC size (RDW) is within normal limits.
