Chapter 1 Hematology and coagulation Learning goal: Interpret CBC and coagulation tests. Hematology reference ranges (typical adult) Hemoglobin (F/M); g/dL; 17.5; x10^3/uL; Platelets; x10^3/uL; INR (no warfarin) 0.8; 1.1; aPTT

sec Teal = typical adult reference range; pink = outside range. Labs vary by facility.; Figure 1.1; Drug; Monitor; Antidote; Warfarin; INR (often 2-3 therapeutic); Vitamin K; Heparin (unfractionated); aPTT / anti-Xa; Protamine sulfate; Enoxaparin; Anti-Xa, platelets; Protamine (partial); Dabigatran; Clinical bleeding; Idarucizumab

SAFETY ALERT Platelets below 50,000/uL increase bleeding risk; below 20,000 spontaneous bleeding may occur. Use bleeding precautions: soft toothbrush, electric razor, no IM injections.
