Test Price (INR) 1000-4000
Result Value Presence or absence of bacteria
Normal Value Absence of bacteria
Accuracy High
Interpretation Presence of bacteria, indicating whooping cough

The Polymerase Chain Reaction (PCR) test accurately detects the presence or absence of Bordetella pertussis bacteria in the nasopharyngeal swab, aiding in the whooping cough diagnosis with high accuracy.

 

3. Serology Test

  • Assessing the presence of specific antibodies against the bacteria.
  • Indicates exposure and immune response to whooping cough.
  • Confirms whooping cough diagnosis and evaluates infection stage.
Serology Test Details
Also Known As Antibody test
Purpose Assess the presence of specific antibodies
Sample Blood
Preparation None
Procedure Analyze blood sample
Test Timing 1-2 hours
Test Price (INR) 500-2000
Result Value Presence or absence of specific antibodies
Normal Value Presence of specific antibodies
Accuracy High
Interpretation Presence of antibodies, suggesting previous exposure or vaccination

The serology test assesses the presence of specific antibodies against Bordetella pertussis bacteria in the blood, indicating exposure or vaccination for whooping cough. It provides valuable information for whooping cough test and evaluation with high accuracy.

 

4. Chest X-ray

  • Used to evaluate the lungs in suspected whooping cough cases.
  • Rules out other respiratory conditions and assesses lung severity.
  • Provides valuable information for whooping cough test and treatment planning.
Chest X-ray Test Details
Also Known As CXR
Purpose Evaluate lungs, rule out respiratory conditions
Sample None
Preparation None
Procedure Imaging of the chest to assess lung condition
Test Timing 15-30 minutes
Test Price (INR) 1000-3000
Result Value Visualization of lung structure
Normal Value Clear lung structure
Accuracy Moderate
Interpretation The presence of lung abnormalities or conditions may require further evaluation

The chest X-ray test (CXR) evaluates lung condition, rules out respiratory conditions, and visualizes lung structure for abnormalities. It is an accurate imaging tool for initial evaluation and further interpretation of lung health.

 

5. Blood Tests

  • Aid in the whooping cough test of whooping cough and provide valuable information.
  • Measure white blood cell count and infection markers.
  • Assist in determining treatment options and monitoring the response.
Blood Tests Details
Also Known As Hematological tests
Purpose Measure white blood cell count
Sample Blood
Preparation Fasting required
Procedure Lab analysis of blood sample
Test Timing 2-4 hours
Test Price (INR) 500-3000
Result Value White blood cell count
Normal Value Range varies for different markers
Accuracy Variable
Interpretation Abnormal values indicate infection or other conditions requiring further evaluation

Blood tests, also known as hematological tests, measure white blood cell count and infection markers. They provide valuable information for initial evaluation, aiding in the detection of infections and other conditions.

Nasopharyngeal Swab, Polymerase Chain Reaction (PCR), and Serology tests are used to detect Bordetella pertussis and assess antibodies. They provide accurate results for diagnosing whooping cough and guiding treatment decisions.

 

Whooping Cough Differential Diagnosis

Similar Disease Differentiating Factors
Pertussis Paroxysmal coughing fits with a "whooping" sound, post-tussive vomiting
Asthma Recurrent episodes triggered by specific stimuli, wheezing, shortness of breath
Gastroesophageal Reflux Disease (GERD) Symptoms related to acid reflux, heartburn, regurgitation
Respiratory Syncytial Virus (RSV) Infection Rapid breathing, wheezing, chest congestion, lower respiratory tract involvement

Differential diagnosis for Whooping Cough includes similar diseases such as bronchitis, asthma, GERD, and RSV infection. Differentiating factors include paroxysmal coughing fits with "whooping" sound and post-tussive vomiting.

Whooping Cough Diagnosis FAQ

How is whooping cough diagnosed?

Whooping cough is diagnosed through a combination of clinical evaluation, medical history, and laboratory tests. Nasopharyngeal swab tests, PCR tests, and serology tests are commonly used to detect the presence of the Bordetella pertussis bacteria or specific antibodies in the body.

What tests are used to diagnose whooping cough?

The tests commonly used to diagnose whooping cough include nasopharyngeal swab tests, polymerase chain reaction (PCR) tests, serology tests (antibody tests), chest X-rays, and blood tests. These tests help detect the presence of the Bordetella pertussis bacteria or specific antibodies in the body, aiding in accurate diagnosis.

How important is early diagnosis and treatment for whooping cough?

Early diagnosis and treatment of whooping cough are crucial for several reasons. Timely identification allows for appropriate management, reducing the severity and duration of symptoms. It also helps prevent the spread of the infection to others, especially vulnerable populations like infants and young children. Early treatment with antibiotics can effectively treat the infection and reduce the risk of complications.
