Scarlet fever urine routine examination

Scarlet fever is usually diagnosed through routine urine tests, which is more intuitive. If there is protein in the urine, consider the possibility of scarlet fever. There are many other tests that can reflect this disease. This bacterial infection is best confirmed by combining multiple tests. No matter which type of examination is done, you cannot make a random judgment. You need to combine more manifestations to make a diagnosis. In the early stages of scarlet fever, symptoms such as dizziness and fever are common, but they are not a big problem.

2. Urine. Generally there may be a small amount of protein, which is usually transient. When complicated by nephritis, protein increases, and red and white blood cells and casts appear.

3. Culture and smear of secretions. Throat swab or pus culture, isolation of group A beta-hemolytic streptococcus. Throat swab smear immunofluorescence method can also be used to detect group A β-hemolytic streptococcus.

4. The rash fading test is positive.

5. The polyvalent erythrotoxin test is positive in the early stage of the disease and negative in the recovery period.

6. X-ray, electrocardiogram and other examinations.

1. Drug rash: It can also cause scarlet fever-like rash. Other rash-causing diseases such as measles and rubella need to be differentiated from scarlet fever. The symptoms of "scarlet fever-like" caused by Streptococcus mitis infection are often severe and may cause liver and kidney damage or shock. Bacterial culture is required for identification.

2. Staphylococcus aureus infection: The molecular structure of endotoxin of some strains of Staphylococcus aureus is partially the same as that of scarlet fever toxin, which can also cause scarlet fever-like rash. However, the rash disappears quickly without peeling, and is often accompanied by migratory lesions. Pathological examination revealed Staphylococcus aureus.

It is recommended that parents take their children to a regular hospital for examination. Once the diagnosis is confirmed, the child needs to be isolated and treated actively immediately. Subsequent treatment and care plans also need to be carried out after consulting a doctor and following the doctor's instructions.
