Usually, at this stage, there is no specific hospital that can check formaldehyde in the body in a tertiary hospital or a tertiary hospital in a provincial capital city. If you need to check formaldehyde in the body, you need to go to a hospital for the prevention and treatment of occupational diseases or a poison center in a designated hospital to find out the formaldehyde content in the body. But in the occupational disease or poisoning center, it is only able to determine whether the formaldehyde in the body exceeds the standard according to the patient’s clinical symptoms, clinical signs, the doctor’s experience and other relevant auxiliary examinations, or use the environmental monitor to monitor whether the formaldehyde content is too high in the environment in which it is located to determine whether the formaldehyde remains in the body, so at present, according to the formaldehyde in the body check, it is not possible to fully confirm the diagnosis of formaldehyde poisoning.
