What does this test include?
This published blood panel contains HBsAg for hepatitis B, anti-HIV-1/2, syphilis serology, and Chlamydia trachomatis IgG and IgM antibodies. It does not list a urine, swab or molecular test as part of the package.
Why might it be ordered?
- After a possible sexual exposure, with timing agreed with a clinician because window periods differ.
- During sexual-health screening or pregnancy planning when this combination has been recommended.
What sample is needed?
A blood sample is required. The laboratory chooses the correct tube and handles the sample for this test.
How should you prepare?
Fasting is usually not the main issue. Tell the clinician when the possible exposure occurred so the right tests and repeat timing can be chosen.
How are the results reported?
A reactive screening result may need confirmation. Chlamydia antibodies alone cannot determine whether a current genital infection is present; a clinician may recommend a molecular test (NAAT) from urine or a swab.
