3Blood Test
A blood test is also helpful in diagnosing whooping cough. All you need to do is to provide a blood sample, which will be tested in the lab for any sign of infections. In most cases, both viruses and bacteria that cause whooping cough tend to increase the number of white blood cells in your body. This indicates that the immune system is working hard to prevent the infection. The results of a blood test, therefore, would confirm the presence of this health issue. Some methods can check for pertussis antibodies, especially in acute cases. [3]
