Anti Dnase B Test

Anti Dnase B Test and its Function

The Anti-DNase B test is particularly useful in determining if an individual has had a recent GAS infection. After a streptococcal infection, the body produces antibodies, including Anti-DNase B antibodies, in response to the bacterial enzymes. The test measures the level of Anti-DNase B antibodies in the blood, which typically rise two to three weeks after the initial infection.

Conditions that may require Anti Dnase B Test

If an individual presents with symptoms and signs suggestive of a recent GAS infection, such as sore throat, fever, swollen tonsils, or skin rash, an Anti-DNase B test may be conducted. Elevated levels of Anti-DNase B antibodies in the blood can confirm recent exposure to GAS and support the diagnosis of a recent streptococcal infection.

Anti Dnase B Test Procedure

The Anti Dnase B Test is a simple blood test that can be performed in a laboratory. Before the test, the patient may be asked to avoid certain medications that may affect the results. During the test, our healthcare professional will use a needle to draw blood from a vein in the patient's arm. The blood sample will then be sent to our laboratory for analysis.

Interpreting Anti Dnase B Test Results

Elevated levels of Anti-DNase B antibodies in the blood indicate recent exposure to group A Streptococcus (GAS) bacteria. The rise in Anti-DNase B antibody levels typically occurs around two to three weeks after a GAS infection. If the Anti-DNase B antibody levels are significantly above the reference range, it suggests a recent streptococcal infection.
