A combined screening panel used to detect common sexually transmitted infections. Helps in early diagnosis, treatment planning, and reducing transmission. Often includes tests for HIV, Syphilis (VDRL/TPHA), Hepatitis B, Hepatitis C, Chlamydia, Gonorrhea, and sometimes Trichomonas/HSV depending on the package.

Chlamydia:

• Risk Assessment: Unprotected sex with multiple partners, not using condoms, prior STD history.

Syphilis:

• Risk Assessment: High-risk behavior, multiple partners, or exposure to someone with syphilis.

HIV (Human Immunodeficiency Virus):

• Risk Assessment: High-risk sexual behavior, sharing needles, or unprotected sex with multiple partners.

Hepatitis B and C:

• Risk Assessment: Unprotected sex, injection drug use, previous blood transfusions, tattoos or piercings in unregulated settings.

Trichomoniasis:

• Risk Assessment: Unprotected sexual activity with infected partners.

Normal Range

• HIV 1/2: Non-reactive

• VDRL/RPR: Non-reactive

• TPHA/TPPA: Negative

• HBsAg: Negative

• Anti-HCV: Negative

• Chlamydia : Negative

Interpretation

• HIV (1&2) Antibody/Antigen

  • Reactive: Suggests infection → confirm with differentiation assay.

  • Non-reactive: No infection or window period.

• Syphilis (VDRL/RPR + TPHA)

  • VDRL/RPR reactive + TPHA positive: Active or past infection → titer monitoring.

  • VDRL reactive, TPHA negative: Possible biological false positive.

• HBsAg

  • Positive: Hepatitis B infection.

  • Negative: No infection or early window.

• Anti-HCV

  • Positive: Past or current infection → confirm with HCV RNA.

  • Negative: No exposure.

• Chlamydia

  • Positive: Active infection → treat + partner treatment.

  • Negative: No infection.

Blood: For detecting HIV, syphilis, herpes, and hepatitis.

Urine: For detecting chlamydia, trichomoniasis.
