Occult blood test and hemosiderin test

The occult blood test and hemosiderin test are chemical or monoclonal antibodies that can detect trace amounts of respiratory tract bleeding or sputum suspected of respiratory tract bleeding or hemorrhage caused by blood vessel hemolysis. Prussian blue staining can be used to check hemosiderin in sputum. Occult blood test and hemosiderin test: A small amount of respiratory tract or suspected respiratory tract sputum can be examined by chemical method or monoclonal antibody method. Basic Information Specialist classification: Respiratory examination classification: biochemical examination Applicable gender: whether men and women apply fasting: not fasting Tips: Clean the body one day before the urine occult blood test. Normal value In normal people, the occult blood test is negative, and the urinary occult blood reaction is normal when the test is negative.

Common in lung congestion, bronchiectasis, lung cancer and tuberculosis and other diseases. Due to the large amount of hemosiderin produced by the hemoglobin degeneration in sputum, it is found in lobar pneumonia, pulmonary infarction, idiopathic pulmonary hemosiderosis. The people who need to be examined include patients with suspected symptoms such as pulmonary congestion, bronchiectasis, lung tumors and tuberculosis, lobar pneumonia, pulmonary infarction, and idiopathic pulmonary hemosiderosis.

Inspection process Occult blood test and hemosiderin test: A small amount of respiratory tract or suspected respiratory tract sputum can be examined by chemical method or monoclonal antibody method. The common chemical methods used in occult blood tests are guaiac and the benzidine method. The immunoassay is mainly a monoclonal occult blood test method.
