Lung injury is damage to the lung tissue caused by trauma, infection, inhalation of toxic substances, or severe respiratory conditions. It often leads to inflammation, fluid accumulation, and impaired oxygen exchange that can progress to acute respiratory distress syndrome (ARDS). The Creatine Kinase (CK) Total test is the most important blood test for monitoring lung injury complications because it detects muscle tissue damage associated with severe respiratory distress.

Lung injury is caused by direct trauma to the chest, inhalation of toxic fumes or chemicals, severe infections like pneumonia, aspiration of stomach contents, or drowning incidents. Indirect causes include sepsis, massive blood transfusions, and severe systemic inflammation that affects the lungs even when the initial problem started elsewhere in the body. The injury triggers an inflammatory response that damages the delicate air sacs (alveoli) in the lungs, causing fluid to leak into the air spaces and making it difficult to breathe.
The Creatine Kinase (CK) Total test is the most important blood test for lung injury because it detects elevated levels of this muscle enzyme that indicate tissue damage associated with severe respiratory complications like acute respiratory distress syndrome (ARDS). While lung injury is primarily diagnosed through chest X-rays, CT scans, and arterial blood gas measurements, the CK test helps healthcare providers monitor the systemic impact of the injury and assess whether muscle tissue is being damaged. Elevated CK levels can signal that the condition is progressing to more serious complications requiring intensive treatment.
You should get tested if you experience sudden severe shortness of breath, rapid breathing, extreme difficulty getting enough air, bluish discoloration of the lips or fingernails, or confusion after a trauma, toxic exposure, or severe infection. Testing is also important if you have been hospitalized for pneumonia, sepsis, or serious injuries and your breathing continues to worsen despite treatment. Anyone who has inhaled smoke, chemicals, or water and develops breathing problems within hours or days should seek immediate medical evaluation and testing.

What this means
Your Creatine Kinase level is moderately elevated, which suggests recent muscle stress or minor damage. This is common after intense workouts, physical labor, or minor injuries, though it can also indicate underlying muscle conditions if levels remain high without obvious cause.
Recommended actions
Avoid intense exercise for 48-72 hours and allow muscles adequate recovery time
Stay well-hydrated with water and electrolyte-rich fluids to support muscle function
Apply ice to sore areas and consider gentle stretching or massage for recovery
Retest in 2-4 weeks to ensure levels return to normal range
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
