Tests for Whooping Cough

Here are  three types of Whooping Cough tests:

• Bacterial Culture: A sample is collected and the bacteria Bordetella pertussis are grown on an agar plate. It can take up to 7 days for results.
• Polymerase Chain Reaction (PCR): Genetic material (DNA) from the bacteria is detected in the sample. Results are typically available within a few hours.
• Blood Test for Antibodies (Serology): Antibodies produced by the body's immune system in response to B. pertussis are detected. This test is most useful after 3-4 weeks of symptoms.

Pertussis Test Means

Pertussis Test is a diagnostic examination used to detect infection with Bordetella pertussis, the bacterium responsible for whooping cough.

• It helps confirm the presence of pertussis when individuals exhibit symptoms such as severe coughing fits and may have been exposed to the infection.
• The test can involve a nasopharyngeal swab, nasal aspirate, or a blood sample, depending on the stage of the infection and the timing of the test.
• Accurate diagnosis is crucial for early treatment and limiting the spread of the highly contagious pertussis.
• Cost and reporting time may vary, so consulting a healthcare provider or laboratory is recommended for specific details.
