Sputum Pathogen Test

Sputum is a secretion produced by the trachea, bronchi, and alveoli. The pathogen test of sputum is one of the basis for the diagnosis of respiratory tract, lung infection and nature. Common pathogens are Streptococcus pneumoniae, Mycobacterium tuberculosis, Haemophilus influenzae, Legionella pneumophila, Candida albicans, Mycoplasma pneumoniae and respiratory viruses. Basic Information Specialist classification: Infectious disease inspection and classification: pathogenic microorganism inspection Applicable gender: whether men and women apply fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: A small number of bacteria in the normal flora of the upper respiratory tract can be seen. Positive: The pathogenic bacteria are cultured in the sputum. Tips: Avoid taking blood as a sample to be tested during infusion and medicine. Normal value A small number of bacteria in the normal flora of the upper respiratory tract can be seen. Clinical significance Common pathogens are Streptococcus pneumoniae, Mycobacterium tuberculosis, Haemophilus influenzae, Legionella pneumophila, Candida albicans, Mycoplasma pneumoniae and respiratory viruses. In order to distinguish whether the microorganism isolated in the sputum is a pathogen or a normal flora of the upper respiratory tract, it is generally required to be cultured three times in a row, such as three times being the same microorganism, often as a pathogen; for example, culturing Mycobacterium tuberculosis in sputum, put Line bacteria, Nocardia and Legionella pneumophila have clinical significance; if the normal flora of the nasopharyngeal cavity such as Haemophilus influenzae, Candida, Mycoplasma pneumoniae is isolated, the number of microorganisms is determined. Parasitological examination of the amoeba trophozoites found in amebiasis; paragonimiasis eggs found in paragonimiasis Pneumocystis sinensis eggs found in pulmonary sputum disease. Positive results may be diseases: pulmonary hysterasis, pulmonary metastatic tumor, parrot fever, lung anthrax precautions 1. In order to reduce fluctuations in test results caused by blood collection time, it is best to fix the blood at each time at the same time. 2, the tourniquet compression time can not be too long, too long may cause a variety of composition changes and intravascular hemolysis. 3, to avoid infusion, take blood as a sample to be tested. 4, timely inspection. Inspection process The normal flora of the nasopharyngeal cavity such as Haemophilus influenzae, Candida, and Mycoplasma pneumoniae is isolated, and the number of microorganisms is determined. Not suitable for the crowd Those who do not have an indication for examination should not do this check. Adverse reactions and risks Generally no complications and harm.
