Study sheet
Build the sheet you actually need.
Pick panels and print their reference ranges, SI equivalents, and critical values on one page - from the same 117 tests as the rest of the reference. Every panel page is free to read and free to print on its own; Premium is what merges several onto a single sheet.
Complete Blood Count (CBC)
| Test | Conventional | SI | Critical |
|---|---|---|---|
| Absolute Neutrophil Count (ANC) | 2500-7000 cells/µL | 2.5-7 10⁹/L | < 500 cells/µL is severe neutropenia (high infection risk) |
| Basophils (%) | 0-1 % of WBC | 0-0.01 fraction | - |
| Eosinophils (%) | 1-4 % of WBC | 0.01-0.04 fraction | - |
| Hematocrit (Hct) | 36-52 % | 0.36-0.52 proportion of 1.0 | < 20% or > 60% |
| Hemoglobin (Hgb) | 12-17.5 g/dL | 120-175 g/L | < 7.0 g/dL (70 g/L) usually prompts transfusion consideration; > 20 g/dL |
| Lymphocytes (%) | 20-40 % of WBC | 0.2-0.4 fraction | - |
| Mean Corpuscular Hemoglobin (MCH) | 27-33 pg/cell | 27-33 pg | - |
| Mean Corpuscular Hemoglobin Concentration (MCHC) | 32-36 g/dL | 320-360 g/L | - |
| Mean Corpuscular Volume (MCV) | 80-100 fL | 80-100 fL | - |
| Monocytes (%) | 2-8 % of WBC | 0.02-0.08 fraction | - |
| Neutrophils (%) | 40-70 % of WBC | 0.4-0.7 fraction | - |
| Platelet Count | 150-400 10³/µL | 150-400 10⁹/L | < 50 × 10⁹/L (bleeding risk) - spontaneous bleeding risk rises sharply < 20; > 1,000 |
| Red Blood Cell Count (RBC) | 4.2-5.9 10⁶/µL | 4.2-5.9 10¹²/L | - |
| Red Cell Distribution Width (RDW) | 11.5-14.5 % | 11.5-14.5 % | - |
| Reticulocyte Count | 0.5-2.5 % of RBC | 0.005-0.025 fraction | - |
| White Blood Cell Count (WBC) | 4.5-11 10³/µL | 4.5-11 10⁹/L | < 2.0 or > 30.0 × 10⁹/L (severe neutropenia or marked leukocytosis) |
