How to check for hand, foot and mouth disease

Many patients often cause a lot of unnecessary trouble to their health due to their lack of understanding of the disease. Take hand, foot and mouth disease as an example. If it is not treated in time, it can easily delay the patient's condition. So how to check whether you have hand, foot and mouth disease? Here is a brief introduction for you.

Laboratory tests

1. Peripheral blood leukocytes: In most cases, the total number of leukocytes and neutrophils is normal. In severe cases, the leukocyte count may be significantly increased.

2. Blood biochemical examination: Some cases may have mild elevation of ALT, AST, and CK-MB, and severe cases may have elevated blood sugar.

3. Pathological examination: specific EV71 nucleic acid is positive or EV71 virus is isolated.

4. Serological examination: Specific EV71 antibody test is positive. The complement test is the most sensitive, and positive results can be obtained 10 to 20 days after onset.

5. Cerebrospinal fluid examination: clear appearance, increased pressure, leukocytosis (multinuclear cells may be more than monocytes in critical cases), normal or slightly increased protein, normal sugar and chloride. When there are complications of the central nervous system, the number of cerebrospinal fluid cells may increase and the protein may rise.

6. Based on the clinical diagnosis, a positive EV71 nucleic acid test, isolated EV71 virus or positive EV71 IgM antibody test, or a 4-fold increase in EV71 IgG antibody or a change from negative to positive can confirm the diagnosis.

Physical examination

1. Chest X-ray: It may show increased texture in both lungs, grid-like, dot-like, and large-scale shadows. In some cases, it is more unilateral and rapidly progresses to large bilateral shadows.

2. Electrocardiogram: No specific changes. Sinus tachycardia or bradycardia and ST-T changes may be seen.

3. Magnetic resonance imaging: mainly damage to the brainstem and gray matter of the spinal cord.

4. Electroencephalogram: Some cases may show diffuse slow waves, and a few may have spike (point) slow waves.

For patients with hand, foot and mouth disease, there are so many examination methods to choose from, so when parents find that their children have some symptoms of hand, foot and mouth disease, don't worry, any of the above examination methods will determine the child's condition. If the child really has hand, foot and mouth disease, appropriate treatment measures should be taken.
