Anti-DNase B (Streptococcal) Antibodies Blood Test

What is the purpose of this test?

The Anti-DNase B (Streptococcal) Antibodies Blood Test is a test that helps healthcare providers find out if a person has been infected with a type of bacteria called Streptococcus. The test works by checking if there are certain antibodies in a person's blood that fight against a specific enzyme produced by Streptococcus called DNase B. This test is usually done to help healthcare providers diagnose a streptococcal infection, such as strep throat or scarlet fever, when it's not clear what is causing the symptoms. It can also help healthcare providers check if the treatment for the infection is working. The test is simple and involves taking a small blood sample from the patient. The sample is sent to a laboratory for analysis. 

Overall, the Anti-DNase B (Streptococcal) Antibodies Blood Test is an important tool for healthcare providers to diagnose and treat streptococcal infections. It helps them quickly determine if the bacteria is present and prescribe the right treatment, which can help prevent complications and stop the infection from spreading to others.

Who would benefit from this test?

This Anti-DNase B Antibodies Blood Test may be beneficial for individuals who:

• Have had a recent streptococcal infection
• Are suspected of having post-streptococcal complications such as rheumatic fever or glomerulonephritis

What do my results indicate?

An Anti-DNase B Antibodies Blood Test is usually done to check if a person has had a recent Streptococcus infection. Specifically, this test measures the levels of antibodies the body produces against DNase B, an enzyme that Streptococcus bacteria produce. If the test reveals high levels of antibodies, it suggests that the person had a recent or ongoing Streptococcus infection. On the other hand, low levels of antibodies imply that the person has not had a recent or ongoing infection. It's essential to note that other factors may affect the test results, so the interpretation of the results should be done by a healthcare professional.
