Blood test generally refers to blood laboratory tests. Hand, foot and mouth disease cannot be detected by ordinary blood tests, but it can be detected by virus-specific IgM antibodies in the blood, but it needs to be combined with physical examination and so on to help diagnose the disease.
1. Blood test: Serologic examination of blood test reveals positive enterovirus-specific IgM antibody, which helps to diagnose HFMD.
2. Physical examination: It can help to determine the diagnosis by examining the body and observing the location of the rash (mostly on the hands, feet, mouth and buttocks, and occasionally on the trunk) and the character of the herpes (there may be a red halo around it, and the fluid in the blisters is relatively small).
3. Pathogenetic examination: Nasal, pharyngeal and airway secretions, herpes fluid or fecal specimens will be taken from the patient, and enteroviruses will be found, then the diagnosis of HFMD can be confirmed.
After the diagnosis of HFMD is confirmed, the patient should actively cooperate with the doctor for treatment so as not to affect the patient’s quality of life.
