To determine whether a medical condition is severe, one cannot rely solely on a single test but must consider clinical symptoms and other diagnostic results comprehensively. For instance, Mycoplasma infection can lead to pneumonia, known as Mycoplasma pneumonia. If there is severe fever, especially persistent high fever, the condition is likely more serious. Furthermore, if there are extrapulmonary manifestations, such as dermatitis, pleural effusion, or otitis media, the situation is also relatively severe. Additionally, if lung imaging shows extensive or numerous shadows, it indicates a more serious condition.
