Specific tests for diarrhea in children

In the process of raising children, we all have some knowledge about pediatric diseases. We all know that diarrhea in children is very common. However, if diarrhea is accompanied by vomiting and diarrhea cannot be stopped in time, it will be extremely harmful to children. In severe cases, it will cause hair loss. So when children have diarrhea, what examination items should be done? The following content will introduce some specific items that need to be checked.

1. Stool test Stool examination is very important for diarrhea, and other tests cannot completely replace it. Bacterial culture: Some children have diarrhea for a long time, or have repeated diarrhea, or have repeated bloody stools, and do not get better after treatment. Stool bacterial culture is needed to understand whether there is any special bacterial infection.

2. Routine blood examination shows that the total number of white blood cells is mostly normal, with a few slightly increased, and there may be an increase in lymphocytes in the cell classification. Stool examination: The appearance is yellow watery loose stools, without mucus, pus and blood, and there are mostly no abnormalities in microscopic examination. 1) For children with normal stool examination but accompanied by fever, a routine blood test is performed to observe whether the white blood cell count is increased or decreased, or to check some viscosity indicators to provide the doctor with a basis for diagnosis. 2) Some children may need blood tests to check blood potassium, sodium, and chloride ions to reflect the situation and degree of water loss in the body, and rehydration is performed based on these conditions. 3) Some children may also have blood tests to check the heart, liver, and kidney enzymes to help doctors determine whether there is damage to other organs. The earlier the discovery, the better the child's recovery.

3. Serum antibody test for rotavirus uses immunological methods such as EIA to detect specific antibodies in the patient's serum. If the antibody titer of the double serum samples from the acute phase and the recovery phase increases by 4 times, it has diagnostic significance.

4. Other examinations 1) For some children with severe or prolonged diarrhea, poor treatment effects, blood in the stool, or malnutrition, further examinations are needed, such as genetic metabolic disease screening, B-ultrasound or endoscopic examination (such as colonoscopy), etc. 2) Children with convulsions also need some neurological examinations to determine whether there are intracranial problems. Or a head CT scan is needed to determine whether there is intracranial bleeding (some infants and young children with intracranial hemorrhage or intracranial tumors may show diarrhea).

The above content introduces the examinations that should be done for children with diarrhea. When children have diarrhea, the above examinations can be used to find out the specific cause of the diarrhea, so that symptomatic treatment can be better carried out. It is recommended that parents go to a regular hospital for examination and treatment when they find that their children have diarrhea, and never blindly use medication.
