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 testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
