Frequently Asked Questions

What is serology testing?

Serology testing is a type of laboratory blood test that detects antibodies or antigens in the serum to help diagnose infections, immune responses, and certain medical conditions by examining how the immune system reacts.

Why are serology tests done?

Serology tests are done to check whether you’ve been exposed to specific pathogens, to assess immune response after infection or vaccination, and to help diagnose autoimmune disorders and certain other conditions.

How does a serology test work?

A serology test works by analysing a blood sample to detect the presence of antibodies produced by the immune system in response to foreign substances, indicating past infection or immune reaction.

What conditions can serology tests help diagnose?

Serology tests can help diagnose infections like hepatitis, HIV, dengue, syphilis, and other viral or bacterial diseases, as well as autoimmune diseases by identifying specific antibodies in the blood.

Are serology tests used to check immunity?

Yes — serology tests can be used to determine if you have developed antibodies after vaccination or past infection, giving insight into your immune status against certain diseases.

Is a serology test painful?

Serology tests involve a standard blood draw from a vein, which may cause slight discomfort or a brief pinch, but the procedure itself is generally quick and well tolerated.

How long does it take to get serology test results?

Serology test results are typically available within a few days, depending on the laboratory’s workflow and the specific tests being performed.

Do I need any preparation before a serology test?

Most serology tests do not require special preparation, though your healthcare provider may give instructions based on the specific condition being tested or if combined with other tests.

Can serology tests detect current infection?

Serology tests primarily detect antibodies which indicate past exposure or immune response; they may not reliably detect a very recent or current infection without other confirmatory tests.

Are serology tests safe?

Yes — serology tests are safe diagnostic procedures that use a blood sample to provide important information about immune responses, infections, and disease risk.
