Understanding Abnormal Sputum Culture Results: What They Mean

Abnormal sputum culture results may indicate:

  • Presence of atypical bacteria/fungi: Suggests infection (pneumonia, bronchitis, tuberculosis).
  • High bacterial/fungal count: Also indicates infection.
  • Antibiotic-resistant bacteria: Not killed by standard antibiotics; complicates treatment.
  • Blood or pus in sputum: May signal serious infection or other lung condition.
