laboratory reference intervals
Typical adult reference ranges for the parameters in your table are below. Exact limits vary slightly by laboratory, age, sex, pregnancy status, and method.
| Parameter | Usual adult normal range |
|---|---|
| Urea nitrogen (BUN) | 7-20 mg/dL |
| Serum urea | About 15-40 mg/dL |
| Creatinine | 0.6-1.2 mg/dL |
| Sodium (Na⁺) | 135-145 mEq/L |
| Potassium (K⁺) | 3.5-5.0 mEq/L |
| Bicarbonate (HCO₃⁻) | 22-28 mEq/L |
| Chloride (Cl⁻) | 96-106 mEq/L |
| Hemoglobin | Male: 13.5-17.5 g/dL; Female: 12.0-16.0 g/dL |
| PCV / Hematocrit | Male: 41-53%; Female: 36-46% |
| Platelet count | 150-450 × 10⁹/L or 1.5-4.5 lakh/µL |
| WBC / TLC | 4,000-11,000/µL or 4-11 × 10⁹/L |
| Polymorphs / Neutrophils | 40-70% |
| Lymphocytes | 20-40% |
| Monocytes | 2-8% |
| Eosinophils | 1-4% |
| CRP | Usually <5 mg/L. It should be reported in mg/L or mg/dL, not %. |
| RDW-CV | 11.5-14.5% |
The listed urea range of 7-20 mg/dL in the image is conventionally the range for BUN, not total serum urea. Standard electrolyte and renal reference intervals are also shown in the NBME laboratory values table.
From the values visible in the image, creatinine 5.4 mg/dL is markedly high, hemoglobin 11.5 g/dL is low for most adults, and RDW-CV 18% is high. CRP “12%” needs verification of the unit and the laboratory report.
