Interpreting Lung Function Tests
Deoxygenated blood enters the lungs from the right side of the heart and travels to the lungs. When you inspire, oxygen flows into the lungs, transverses the capilliares and attaches to hemoglobin down a gradient. At the same time, co2 diffuses into the capilaries and is expelled with exhalation. Oxygen rich blood then flows to the left side of the heart and into the ...Read more
Several labs: To assess kidney function, the BUN and creatinine levels will be checked. They can be compared to the levels in the urine too. A better measure is called the GFR or glomerular filtration rate. A urinalysis to look for protein, blood, concentration ability, and so on is also helpful. ...Read more
Electrical: The evaluation depends on history, physical and what the apparent electrical malfunction is. There are many possible tests and no fixed menu of evaluation. ...Read more
What type of doctors perform pulmonary function tests/exercise stress test/cardio-pulmonary stress tests?
Cardiologist: Cardiologist and pulmonary specialist.Get a more detailed answer ›
Cardiac MRI, CTPA, EGC 's, echo's, Chest X-rays, PET scan, blood tests, ECG stress test. All these tests, no diagnosis. Could something been missed?
Yes: Liver function tests are often elevated in autoimmune hepatitis. This is a non- specific test. If the liver function tests are elevated additional diagnostic tests will be necessary. The anti smooth muscle antibody is one of the most important in pointing to this diagnosis. Tests for other liver diseases such as hepatitis and primary biliary cirrhosis are usually part of the evaluation. ...Read more
Nearly essential: Asthma is not one illness, but several processes that appear in greater or lesser degrees in any one affected individual. Together they can lead to the functional problems we recognize as asthma. Pulmonary function tests measure air flow and volumes; accurately performed PFT's are indispensable in the diagnosis and management of asthma and COPD. ...Read moreSee 1 more doctor answer
Besides spirometry test, x ray, echocardiogram at rest, are there any other tests to detect heart failure? Blood tests? Stress test?
Yes: A cardiac catheterization can determine heart function as well as measure pressures. Spirometry measures lung function, not heart failure. Sometimes this is checked to rule out pulmonary dysfunction as a contributor to the patient's problems. Nuclear scans and specialized ct scans can also give this information. As already mentioned, there is also a blood test called bnp. ...Read moreSee 1 more doctor answer
Would lung cancer cause enlarged hilar and mediasternal nodes, GGO on Chest CT and impaired gas exchange. Other lung function tests are normal?
Possibly: There are many different forms of lung cancer however the most common types usually appear as a solitary nodule or mass on CT. GGO can be seen with lymphatic involvement as is suggested by the enlarged lymph nodes described. This can be from infection, cancer or autoimmune diseases such as sarcoidosis and even heart failure. A biopsy of an enlarged lymph node may be required. ...Read more
Yes they may be!: Sure can as these tests are effort dependent and technique dependent. This means ghats if the patient display not produce enough efforts then test may give a falsely low value. The same if the technician doing the test were not competent and not following protocol. If in doubt; have the test repeated elsewhere. ...Read more
Variety: Depends on risk factors. The more risk factors you have the more serious the investigation. Baseline CXR, possibly CAT scan, sputum samples, up to bronchoscopy with washings and possible biopsy or guided needle biopsy for findings. Currently even starting genetic analysis of tumors to help predict response to chemo/radiation. If really worried start with Pulmonologist ...Read more
What would cause on lung function tests, DLCO 60-75%, increased TLC and narrowing of air tubes? Finger o2 monitor 90%. Heart is fine, NAD on chest ct
See below: It would be difficult to say without all the numbers. But, if your TLC is high, then that's an indication of hyperinflation, which goes along with COPD. So does the decreased DLCO. But again, this is just generalities; would be glad to review all you results with you if needed. ...Read moreSee 1 more doctor answer
Cardiology tests seem in clear but pulm CT scan of chest showed hyperinflated lungs and breathing function test was poor. What is next step?
