Respiratory Disease Blood Test

What is Respiratory diseases?

Respiratory diseases are conditions affecting the lungs and airways, including asthma, COPD, pneumonia, and bronchitis. These conditions impair the body's ability to exchange oxygen and carbon dioxide effectively, leading to elevated CO2 levels in the blood and metabolic imbalances. The Comprehensive Metabolic Profile is the most important test for monitoring respiratory disease complications because it detects elevated carbon dioxide levels and assesses kidney and electrolyte function.

What causes respiratory diseases?

Respiratory diseases are caused by various factors including chronic inflammation, infections, environmental exposures, and genetic predisposition. Asthma results from airway inflammation triggered by allergens or irritants, while COPD develops from long-term exposure to harmful particles, primarily cigarette smoke. Pneumonia is caused by bacterial infections like Streptococcus pneumoniae or viral pathogens, and bronchitis results from viral infections or exposure to irritants that inflame the bronchial tubes.

What is the best test for respiratory diseases?

The Comprehensive Metabolic Profile is the most important blood test for monitoring respiratory diseases because it detects elevated carbon dioxide levels that indicate your lungs are not effectively removing this waste product from your blood. This panel also measures kidney function through eGFR and creatinine levels, as well as electrolyte balance including sodium, potassium, and chloride, which can be disrupted by chronic lung conditions and their treatments. While respiratory diseases are diagnosed through lung function tests and imaging, this blood work is essential for monitoring how these conditions affect your overall metabolic health and preventing serious complications like respiratory acidosis.

When should I get tested for respiratory diseases?

You should get tested if you have been diagnosed with asthma, COPD, or other chronic lung conditions and need to monitor how these diseases affect your metabolic function. Testing is especially important if you experience worsening shortness of breath, persistent cough, increased fatigue, confusion, or swelling in your legs, as these symptoms may indicate elevated CO2 levels or kidney complications. You should also get tested if you are on long-term medications for respiratory conditions, as these can affect your electrolyte balance and kidney function.

What are the symptoms of respiratory diseases?
Respiratory diseases cause persistent cough, shortness of breath, wheezing, and chest tightness that interfere with daily activities. You might notice increased mucus production, frequent respiratory infections, fatigue, and difficulty breathing during physical activity or even at rest. In advanced cases, symptoms include bluish lips or fingernails from low oxygen levels, morning headaches from CO2 buildup, confusion, and unintended weight loss from the increased effort of breathing.
Who is at risk for respiratory diseases?
People who smoke or have a history of smoking face the highest risk for developing COPD and chronic bronchitis. Those with family history of asthma or allergies, exposure to secondhand smoke, air pollution, or occupational dust and chemicals are at increased risk. Additional risk factors include frequent childhood respiratory infections, premature birth, gastroesophageal reflux disease (GERD), and weakened immune systems that make you more susceptible to pneumonia and other lung infections.
What happens if respiratory diseases are left untreated?
Untreated respiratory diseases progressively worsen and lead to serious complications including respiratory failure, where your lungs cannot supply enough oxygen or remove sufficient carbon dioxide from your blood. This can cause pulmonary hypertension, heart failure, frequent and severe lung infections, and permanent lung damage. Chronic oxygen deprivation damages other organs including your kidneys, heart, and brain, significantly reducing your quality of life and lifespan.
Can respiratory diseases be diagnosed with a blood test?
Respiratory diseases cannot be diagnosed with blood tests alone but require lung function tests like spirometry and imaging studies such as chest X-rays or CT scans. However, blood tests play a critical role in monitoring how these conditions affect your body by measuring carbon dioxide levels, kidney function, and electrolyte balance. The Comprehensive Metabolic Profile detects metabolic complications from respiratory diseases and helps your healthcare provider adjust treatment to prevent serious issues like respiratory acidosis or organ damage.
How are respiratory diseases treated?
Respiratory diseases are treated with bronchodilators and inhaled corticosteroids that open airways and reduce inflammation, making breathing easier. COPD patients often require supplemental oxygen therapy, while severe asthma may need oral steroids during flare-ups. Additional treatments include antibiotics for bacterial infections like pneumonia, pulmonary rehabilitation programs combining exercise and education, and lifestyle modifications such as smoking cessation, which is the most important step for slowing disease progression.
How can I prevent respiratory diseases?
You can prevent respiratory diseases by never smoking or quitting if you currently smoke, as tobacco use is the leading preventable cause of lung disease. Avoid exposure to secondhand smoke, air pollution, and occupational irritants by using protective equipment when necessary. Get vaccinated against influenza and pneumonia to prevent respiratory infections, maintain good hand hygiene, exercise regularly to strengthen your respiratory system, and manage conditions like GERD and allergies that can contribute to lung problems.
What can I do at home for respiratory diseases?
You can manage respiratory diseases at home by using a humidifier to keep airways moist, practicing breathing exercises like pursed-lip breathing to improve lung function, and staying hydrated to thin mucus. Maintain a clean, dust-free environment, avoid triggers like strong perfumes and cold air, and use air purifiers to reduce indoor pollutants. Eat a nutritious diet rich in fruits, vegetables, and omega-3 fatty acids to reduce inflammation, pace your activities to conserve energy, and elevate your head while sleeping to ease breathing at night.

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.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
