HIV / STD
Point-of-care rapid testing for hiv / std. OEM/ODM manufacturer.
Overview
HIV and syphilis are bloodborne/sexually transmitted infections. Screening is standard in antenatal care, blood donation and key-population programs.
Diagnostic Markers & Methods
Antibody tests (HIV-1/2, treponemal syphilis) · HIV p24 antigen · combined HIV/syphilis devices.
Testing Window
HIV antibody: ~3–6 weeks (window period). Syphilis treponemal antibody: ~2–6 weeks.
Interpretation
A reactive HIV/syphilis antibody result is presumptive and must be confirmed per national algorithms (HIV: serial tests; syphilis: non-treponemal RPR titer).
Confirmatory Testing
HIV: serial/differentiation algorithm. Syphilis: non-treponemal RPR/VDRL titer for staging.
The Author's Take
Position: Treat every reactive HIV or syphilis rapid result as presumptive — your program is only as defensible as its confirmation pathway.
- Antibody tests have a window period and false-reactive risk; serial confirmation is non-negotiable.
- Combined HIV/syphilis devices reduce steps in antenatal and blood-bank screening.
- Document the national confirmation algorithm before you sell into a new market.

Frequently Asked Questions
What is the window period for an HIV rapid test?
Antibody tests typically become reactive 3–6 weeks after exposure (window period). A negative result inside the window does not rule out infection — repeat or confirm by antigen/antibody or molecular testing.
Can a syphilis rapid test tell active from past infection?
No — treponemal antibody tests stay positive after treatment. Distinguish active from past infection with a non-treponemal (RPR) titer.
Why do HIV and syphilis get screened together?
Both are bloodborne/STIs with overlapping risk groups and are standard in antenatal and blood-donor screening; combined devices reduce cost and steps.
