How is HAP and VAP diagnosed?

Diagnosis

  1. CBC is a useful initial test for HAP/VAP and is best performed near the point of care.
  2. Culture of respiratory secretions is a primary test for HAP/VAP diagnosis and is also best performed near the point of care.
  3. Noninvasive collection is also recommended in patients with suspected HAP, when possible.
