Sputum immunological examination

The sputum immunological examination is one of the methods for determining the sputum examination of immunoglobulin in sputum. Basic Information Specialist classification: Respiratory examination classification: sputum examination Applicable gender: whether men and women apply fasting: not fasting Tips: Pay attention to normal eating habits and pay attention to personal hygiene. Normal value Healthy people are generally innocent, occasionally with a small amount of white or gray-white mucus, a small amount of neutrophils and epithelial cells in the sputum, no red blood cells and other abnormal components. Clinical significance Abnormal results: various infectious respiratory diseases, such as acute and chronic bronchitis, various types of pneumonia, bacterial lung abscess, bronchopleural fistula, amoebic lung abscess, paragonimiasis, tuberculosis, AIDS, etc. Bronchiectasis, bronchial asthma, lung cancer, cardiac insufficiency, pulmonary congestion, pulmonary embolism, pulmonary hemorrhage, etc. People who need to be examined: Patients with various infectious respiratory diseases such as chronic bronchitis, various types of pneumonia, and bacterial lung abscess. Precautions Forbidden before examination: Pay attention to normal eating habits and pay attention to personal hygiene. Requirements for inspection: Actively cooperate with the doctor. Inspection process Secretory IgA (secretoryimmunoglobulinA) assay: SIgA is the main immunoglobulin of the exocrine fluids such as the respiratory tract, digestive tract and genitourinary tract. It is an important antibacterial, antiviral or anti-toxin immune component on the mucosal surface and is an important anti-infective body. "barrier". The secretory IgA in sputum is generally determined by radioimmunoassay (RIA). When SIgA is reduced, mucosal resistance is reduced and it is susceptible to respiratory infections. Clinically, patients with recurrent pulmonary infection were found to have significantly reduced SIgA in sputum. After effective treatment, the immune function is improved, and in some patients, SIgA can be recovered. Not suitable for the crowd Inappropriate crowd: No. Adverse reactions and risks No related complications or hazards.
