Lung health blood tests measure biomarkers linked to respiratory function, oxygen transport, and inflammation. These tests can help identify chronic obstructive pulmonary disease (COPD), asthma, infections, or other conditions that affect breathing. Markers may include oxygen saturation, arterial blood gases, inflammatory proteins, and immune responses that impact lung performance. Our lung health panels provide valuable insights into respiratory wellbeing, helping to detect problems early and support long-term breathing health.
