Fever-related laboratory tests can generally be performed within 24 hours of onset. These tests primarily aim to identify the underlying cause of the fever, enabling targeted treatment. In daily life, it is important to drink plenty of water, which helps flush toxins from the body, promotes metabolism, and may also aid in reducing fever. Additionally, adequate rest is essential—avoid excessive physical exertion.
