Can gastroenteritis be detected by blood test

Gastroenteritis is a type of gastritis and is a common digestive system disease caused by bacterial infection in summer and autumn. Once you suffer from gastroenteritis, although it does not have much impact on other organs of the body, the digestive system will produce strong discomfort, causing symptoms such as stomach pain, bloating or gastric bleeding. Therefore, when these symptoms occur, it is necessary to promptly diagnose the cause and prescribe the right medicine. So can gastroenteritis be detected through blood tests?

Enteritis can be checked by blood test, and routine blood tests may show increased white blood cell and red blood cell counts and an increased erythrocyte sedimentation rate. It varies depending on the pathogen. Generally, a preliminary judgment should be made based on the epidemiological history and clinical manifestations. Further diagnosis requires laboratory testing. Bacterial enteritis can be confirmed by culture of vomitus and stool and obtaining pathogenic bacteria. Blood culture can be used for some pathogens such as Salmonella infection.

Viral gastroenteritis can be diagnosed by electron microscopy, immunoelectron microscopy, immunofluorescence, and serological tests such as complement fixation test, enzyme-linked immunosorbent assay, and radioimmunoassay to detect viral antigens and antibodies. The virus can also be isolated by tissue culture. Parasitic enteritis can be directly examined under a microscope to look for pathogens and their eggs. Fungal enteritis can be treated by direct smearing of the stool, examination of fungi under a microscope or stool fungal culture.

Generally, the options include co-sulfamethoxazole (cotrimoxazole), pipemidic acid, gentamicin, and amikacin. Campylobacter jejuni enteritis can be treated with erythromycin, gentamicin, chloramphenicol, etc. Yersinia enterocolitica enteritis is generally treated with gentamicin, kanamycin, co-trimoxazole, tetracycline, chloramphenicol, etc.

Patients with mild Salmonella enteritis may not need antibiotics, while patients with severe cases can use chloramphenicol or trimethoprim-sulfamethoxazole. Invasive Escherichia coli enteritis can be treated with neomycin, colistin and gentamicin with good results. Amoebic dysentery, enteritis caused by Giardia lamblia and Trichomonas can be treated with metronidazole (Flagyl). Schistosomiasis can be treated with praziquantel. Oral nystatin is effective in treating Candida albicans enteritis.

I believe that through the above specific analysis and introduction, people can better maintain their own health and try to choose scientific methods for corresponding treatment, so as to reduce the harm caused by enteritis.
