Introduction
In most cases, a routine blood test can help detect throat inflammation. Throat inflammation may be caused by microbial infections such as bacteria or viruses. A complete blood count can indicate whether the infection is bacterial or viral by assessing the levels of white blood cells and neutrophils. To more accurately confirm whether there is pharyngitis, additional diagnostic methods such as throat swab tests, antibody testing, and physical examinations can be performed.
In general, pharyngitis (sore throat) can be detected through a routine blood test. The specific analysis is as follows:
Blood tests help doctors identify the underlying cause of throat inflammation, distinguishing whether it is caused by bacterial or viral infection. Typically, in cases of bacterial infection, white blood cell count and neutrophil percentage are elevated. In contrast, with viral infections, the total white blood cell count is normal or decreased, while lymphocyte percentage increases. After diagnosis, patients with throat inflammation can, under medical guidance, use treatments such as compound borax solution for mouth rinsing or medications like Yinhuan tablets. It's important to maintain healthy dietary habits, avoid smoking and alcohol, and refrain from consuming spicy or irritating foods to prevent worsening pain and to support throat recovery by minimizing irritation to the pharyngeal area.
Pay attention to sleep habits—avoid staying up late—and maintain a positive mental state with a proper balance between work and rest. Regular physical exercise is also recommended. Consume plenty of fresh fruits and vegetables to effectively replenish nutrients. If the inflammation is particularly severe, it is advisable to seek medical attention promptly and receive standardized treatment under a doctor’s supervision.
