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 more

Erosive gastritis. h.pylori blood test positive, breath test positive, stool antigen test negative, biopsy negative. what to do ?

Erosive gastritis. h.pylori blood test positive, breath test positive, stool antigen test negative, biopsy negative.  what to do ?

Treat it: The positive H. pylori antibody test is not a reliable indicator of current infection. The gold standard for H. pylori treatment is the gastric biopsy, and this is negative in this patient. However, I am impressed by the positive breath test and erosive gastritis. I would have expected stool antigen to be positive, as it mirrors the breath test. Given the discrepant results, treat the patient. ...Read more

How accurate is a spirometry test in diagnosing asthma?

Very but..: Asthma is an intermittent disease, thus a relatively normal lung function test on one occasion does not rule out asthma. However it should be abnormal when you have symptoms and the numbers (fev-1) often improves after bronchodilator . As with all tests, a doctor can only make a diagnosis after having obtained your history, performed a physical exam, and then interpret the lung function results. ...Read more

What blood test show Amyloidosis?

No blood test: There is no blood test to detect amyloidosis. Sophisticated laboratory techniques called electrophoresis or free light chain assays may reveal early evidence of some amyloid proteins. A biopsy is needed to confirm a diagnosis of amyloidosis and determine the specific type of protein involved in the disease. ...Read more

What blood tests will detect coronary heart disease/ heart artery build up? Any tests? Would the d dimer test show?

What blood tests will detect coronary heart disease/ heart artery build up? Any tests? Would the d dimer test show?

No lab tests: Coronary artery disease is mainly diagnosed by assessing one's. Cardiovascular risk as well as sorting out various symptoms. Lab tests to help here would be a full lipid panel as well as a CRP which is a marker of inflammation. These do not detect plaque but do help i risk analysis. D-dimmer is used for venous disease ie blood clots in legs or lungs. ...Read more

What blood tests will detect coronary heart disease/ heart artery build up? Any tests? Would the d dimer test show?

None: The sad reality is that there's no blood test for atherosclerosis. The d-dimer test most assuredly will not. An ultra sensitive c-reactive protein will address the probability of developing buildup but will not tell you if you have it. Electron beam ct which provides calcium score gets you closer but is not a blood test. Please read my comment:. ...Read more

What blood tests will detect coronary heart disease/ heart artery build up? Any tests? Would the d dimer test show?

Cholesterol: Lab tests do not detect impending heart disease.The risk factors for atherosclerosis and vascular disease could serve as markers of risk for cardiac disease. Elevated cholesterol and ldl, low hdl, increases triglycrides are usual risk factors. Other risk factors that are not lab tests are hypertension, smoking, excessive alcohol intake, lack of physical activity. D-dimer will not help. ...Read more

Should i be concerned about a positive mage a 4 test? Mage= melenoma antigen gene? I had early cdt lung cancer blood test. Ct of lungs clear

MAGE A4 Tesring : The mage a4 antigen, even though it was named the melanoma associated antigen, is a non-specific antigen that has been linked to a wide variety of tumors. It's efficacy is still being debated as a stand alone predictor. Your physician should investigate and rule out the most likely malignancies for your age and family history, including early breast and oral cancer, as well as others less likely. ...Read more

What is a tpha quantitative blood test? Can this test detect latent stage syphilis?

What is a tpha quantitative blood test? Can this test detect latent stage syphilis?

Yes it can: The TPHA test (Treponema pallidum hemagglutination) is a confirmatory test for syphilis. Usually it is done only after a positive screening test, such as the VDRL, RPR, or an EIA test. If you have had negative results on one of these plus the TPHA, you can be 100% certain you don't have syphilis and probably never did. ...Read more

Can pulmonary function test for COPD be completed n given results within a day? How accurate is the test to diagnose copd?

Maybe...: The pulmonary function test is performed by a respiratory therapist (usually) and then a pulmonologist interprets the test and sends the result to your doctor. Your doctor may not get the result on the same day as it may take longer than a day for the test interpretation to occur. It is a very accurate test for copd. ...Read more
