FREE NURSING REFERENCE GUIDE
Labs
Build confidence with common panels, recognizable patterns, and values that require prompt clinical attention.
Educational use only. Reference ranges vary by laboratory, age, clinical context, and institutional policy. Always follow the patient’s current orders, laboratory reference range, and clinical guidance.
Start with the panel
Read individual values in context. A panel can reveal relationships that are less obvious when each result is viewed alone.
| Panel | Common components | Pattern to notice |
|---|---|---|
| CBC | WBC, RBC, hemoglobin, hematocrit, platelets | Infection, oxygen-carrying capacity, and bleeding risk |
| BMP | Sodium, potassium, chloride, CO₂, BUN, creatinine, glucose, calcium | Fluid balance, renal function, glucose, and electrolytes |
| CMP | BMP plus albumin, total protein, bilirubin, ALP, ALT, AST | Renal, metabolic, and hepatic relationships |
| ABG | pH, PaCO₂, HCO₃⁻, PaO₂ | Acid-base status, ventilation, and oxygenation |
Recognize the pattern
- Compare the result with the laboratory’s current reference range.
- Look for related values that move together or explain one another.
- Connect the result to assessment findings, medications, intake and output, and recent treatment.
- Prioritize unexpected changes and results that match clinical deterioration.

- Verify the patient and specimen context.
- Assess the patient, including symptoms and trends.
- Review the result against orders, medications, and recent interventions.
- Escalate according to institutional policy and the clinical situation.
- Document the assessment, communication, and response.
