Blood tests that detect antibodies and antigens to diagnose infections and immune-related conditions.
Clinical Serology is the study of blood serum, particularly the antibodies and antigens it contains, to detect current or past infections and certain immune-related conditions. When your body encounters an infection, it produces specific antibodies — serology tests detect these antibodies (or, in some cases, the infectious agent's antigens directly) in your blood.
Serology testing is widely used to diagnose infections such as dengue, typhoid, hepatitis and others, as well as to check immunity status — for example, confirming whether you have developed protective antibodies after vaccination or a past infection.
At Apollo Clinic Shyamnagar, serology samples are processed using standard validated methods, with results interpreted alongside your symptoms and clinical history for an accurate diagnosis.
| Aspect | Details |
|---|---|
| Duration | Sample collection takes 2–5 minutes; results are typically available the same day or within 24 hours depending on the specific test |
| Preparation | No special preparation is usually required; fasting is generally not needed unless combined with another test |
| What Happens | A blood sample is drawn from a vein and tested for the relevant antibodies or antigens |
| Pain/Discomfort | A brief pinch during needle insertion; minor bruising at the site is possible but uncommon |
Serology tests are recommended when an infection is suspected based on symptoms, or when immunity status needs to be confirmed.

This varies by infection — antibodies typically take several days to develop after exposure, so timing matters. Your doctor will advise the right time to test based on your symptoms and when they started.
Not always immediately. If tested too early in an infection, antibodies may not yet be detectable, leading to a false negative. Your doctor may recommend repeat testing if clinical suspicion remains high.
Yes, in many cases. Different antibody types (such as IgM, which appears early, versus IgG, which appears later and can persist) help distinguish a recent infection from one that occurred in the past.
Most serology tests are ordered based on a doctor's clinical assessment of your symptoms, so a consultation is usually recommended first, though some screening tests may be available directly.
