• Point-of-Care Testing (POCT)


  Analytical test done outside the centralized laboratory and near the site where the patient receives treatment
• Other names for POCT

  • Alternate site testing (AST)
  • Bedside testing
  • Near-patient testing
  • Remote testing
  • Satellite testing
  • Rapid diagnostics
• POCT


  • Ranges from a simple procedure (e.g. glucometer) to automated molecular test using portable analyzers and imaging systems
  • Convenient and shorter turnaround time (TAT)
• Warfarin and heparin therapy

  Can be evaluated using coagulation POCT analyzer
• Common coagulation tests


  • PT and International Normalized Ratio (INR)
  • aPTT
  • Activated clotting time (ACT)
  • Platelet function
• Bleeding time


  Non-instrumented test used to evaluate the capillaries for platelet plug formation<|>For pre-surgical screening and detecting hemostasis-related problems
• Arterial Blood Gases


  Measures the level of oxygen, carbon dioxide and acid-base (pH) in the blood<|>Status of the function of the lungs, heart and kidneys
• Electrolytes


  • Sodium
  • Potassium
  • Chloride
  • Bicarbonate
• Sodium


  Helps keep the normal balance of fluids in the body and plays a role in transmitting nerve impulses<|>↑ Na – hypernatremia<|>↓ Na - hyponatremia
• Potassium


  Helps in nerve conduction and muscle function; regulates the acid-base balance and osmotic pressure<|>↑ K – hyperkalemia<|>↓ K – hypokalemia
• Chloride


  Maintains integrity of cells by helping in balancing the osmotic pressure, as well as the acid-base and water balance of the body
• Bicarbonate ion


  Helps transport CO2 to the lungs and regulate pH
