Understanding Lab Tests for Lung Injury
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Lung injury is typically diagnosed through imaging studies, physical examination, and clinical assessment of symptoms. While there isn't a specific blood test to directly diagnose lung injury itself, laboratory testing plays a fundamental role in monitoring the body's response to injury and assessing potential complications.
Recommended Test
Creatine Kinase (CK), Total, Serum
This test measures the level of creatine kinase, an enzyme found in muscle tissue, in the blood. In cases of lung injury, CK levels can become elevated due to damage to muscle tissue associated with severe respiratory conditions. This biomarker is particularly useful for identifying and monitoring serious complications such as acute respiratory distress syndrome (ARDS), helping healthcare providers assess the extent of tissue damage and guide treatment decisions.

Why Blood Testing is Important in Lung Injury
Severe lung injuries can trigger systemic responses that affect multiple organs and tissues throughout the body. Blood tests are essential for detecting these secondary effects, monitoring inflammation levels, and identifying complications such as acute respiratory distress syndrome (ARDS). These tests help healthcare providers assess the severity of the condition and guide appropriate treatment strategies.
Understanding Your Results
Elevated creatine kinase levels in the context of lung injury may indicate significant tissue damage and the development of severe complications. However, CK can also be elevated due to other factors such as recent exercise, muscle trauma, or certain medications. Your healthcare provider will interpret these results in conjunction with your clinical symptoms and other diagnostic findings.
Important Considerations
