When symptoms are vague, doctors may order a CT scan. If a sinusitis patient does not respond to treatment, doctors may order laboratory tests, such as blood tests, sweat tests, nasal fluid tests and biopsies of nasal linings or sinuses, to rule out other conditions.
Routine blood tests. These help in detection of an infection. This infection may lead to increase in the white blood cell counts. Allergies or hay fever giving rise to sinusitis may cause rise in specific type of white blood cells called the Eosinophil.
