Description
Blood, NA, Fasting or Non Fasting: As suggested by doctor
Sample Required:
A blood sample taken from an arm vein.
Test Time:
Usually, the test results are available in a few days.
Test Normal Range:
The test results are reported as units per milliliter (U/mL). The normal range may vary depending on the laboratory’s reference values.
What is the Test?
The Anti DNase B test measures the level of antibodies against the enzyme DNase B in the blood. Elevated levels of these antibodies can indicate recent streptococcal infections, particularly those caused by certain strains of group A Streptococcus bacteria.
Test Procedure:
A healthcare professional will clean the area around a vein in your arm. A needle is inserted into the vein, and a blood sample is collected into a vial or syringe. The blood sample is sent to a laboratory for analysis. Laboratory technicians measure the level of anti DNase B antibodies in the blood sample.
When to Take the Test:
The Anti DNase B test is commonly used to confirm recent streptococcal infections, especially if there is suspicion of conditions like rheumatic fever or post-streptococcal glomerulonephritis.
Who Should Take This Test:
Individuals suspected of having had a recent streptococcal infection or those showing signs of associated complications, such as joint pain or kidney problems, may be advised to take this test.
Precautions for Exceptional Cases (Pregnancy etc.):
If you are pregnant, breastfeeding, or have any existing medical conditions, inform your healthcare provider before taking this test. Pregnancy can sometimes affect the Anti DNase B test results.
FAQs:
Q1: Can the test diagnose streptococcal infections directly?
A: The test does not diagnose the infection itself but rather detects the immune response to the infection, which can help confirm recent exposure to streptococcal bacteria.
Q2: What complications are associated with high levels of Anti DNase B antibodies?
A: High levels of these antibodies may suggest recent streptococcal infections and raise concerns about potential complications such as rheumatic fever or kidney inflammation.
Q3: Can the test results distinguish between different types of streptococcal infections?
A: The test does not differentiate between different strains of streptococcal bacteria; it only indicates exposure to these bacteria.
Q4: Are there any dietary restrictions before the test?
A: Generally, there are no specific dietary restrictions before this test.
Q5: Can the test results be used to monitor ongoing infections?
A: The test is more useful for detecting recent exposures to streptococcal infections rather than monitoring ongoing infections. Other tests may be used for that purpose.
