Description
Serum, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A blood sample is required to perform the Pertussis IgG Antibody test. This is typically obtained through a standard venipuncture procedure.
Test Time:
The results of the Pertussis IgG Antibody test are usually available within a few days to a week after the blood sample is collected, depending on the laboratory’s turnaround time.
Test Normal Range:
The test does not have a specific normal range. Instead, it measures the level of pertussis-specific IgG antibodies in the blood.
What is the Test?
The Pertussis IgG Antibody test measures the concentration of immunoglobulin G (IgG) antibodies specific to the bacterium Bordetella pertussis in the bloodstream. These antibodies are produced by the immune system in response to a pertussis infection or vaccination.
Test Procedure:
A blood sample is collected from the patient. The sample is sent to a laboratory for analysis. In the laboratory, the blood sample is tested for the presence and concentration of pertussis-specific IgG antibodies, often using an enzyme-linked immunosorbent assay (ELISA) or similar methods.
When to Take the Test:
The Pertussis IgG Antibody test may be performed when there is a suspicion of a current or past pertussis infection (whooping cough). It can also be used to assess immunity in individuals who have been vaccinated against pertussis or to determine if recent contact with a pertussis-infected person has led to an immune response.
Who Should Take This Test:
Individuals who exhibit symptoms of pertussis, such as severe coughing fits with a “whooping” sound, may undergo this test to confirm the diagnosis. It can also be administered to those who have been in close contact with someone diagnosed with pertussis.
Precautions for Exceptional Cases (Pregnancy, etc.):
There are typically no specific precautions related to pregnancy for the Pertussis IgG Antibody test. However, individuals should inform their healthcare providers about their medical history and any ongoing medical conditions.
FAQs (Frequently Asked Questions):
Q1: Is the Pertussis IgG Antibody test the same as the pertussis vaccine?
A: No, the test measures the presence of antibodies in the blood, while the pertussis vaccine is administered to stimulate the production of these antibodies. The test assesses whether an individual has immunity to pertussis, either through vaccination or a previous infection.
Q2: Can this test diagnose an active pertussis infection?
A: It can help confirm a pertussis infection if specific antibodies are present, but other tests, such as polymerase chain reaction (PCR) tests or culture tests, may be needed for a definitive diagnosis.
Q3: How long does pertussis immunity last after vaccination or infection?
A: Immunity from the pertussis vaccine may decrease over time. Booster shots are recommended to maintain protection. Immunity from a pertussis infection can also wane, but individuals are often immune for several years after recovery.
Q4: Can adults get pertussis, or is it mainly a childhood disease?
A: Adults can get pertussis, and it can be severe. Vaccination and booster shots are recommended for adults, especially those who are in close contact with infants.
Q5: What are the common symptoms of pertussis?
A: Pertussis symptoms often include severe and persistent coughing fits, followed by a “whooping” sound when inhaling. Other symptoms may include runny nose, sneezing, fever, and fatigue.
