Know the danger zones
Critical values and other thresholds to recognize on sight
A sample of what the reference covers: critical (panic) values alongside staging, toxicity, injury and risk thresholds, each named for what it states.
Absolute Neutrophil Count (ANC)< 500 cells/µL is severe neutropenia (high infection risk)Acetaminophen Level> 150 µg/mL at 4 h post-ingestion risks hepatotoxicityActivated Partial Thromboplastin Time (aPTT)> 70 seconds (bleeding risk)Arterial pH< 7.20 or > 7.60Bicarbonate (CO₂ content)< 15 or > 40 mmol/LBilirubin, Total> 15 mg/dL in neonates (kernicterus risk)
