Comprehensive STD Panel Testing Components

A comprehensive STD panel typically includes tests for syphilis, gonorrhea, chlamydia, HIV, and hepatitis B, with additional tests based on risk factors and symptoms. 1

Core STD Panel Components

Standard Tests

  • Syphilis: Serologic testing (RPR or other tests)
  • Gonorrhea: Testing for Neisseria gonorrhoeae
    • Urethral/urine specimens for all patients
    • Rectal specimens for MSM (men who have sex with men)
    • Pharyngeal specimens for MSM
  • Chlamydia: Testing for Chlamydia trachomatis
    • Urethral/urine specimens for all patients
    • Rectal specimens for MSM
    • Cervical specimens for women
  • HIV: Serologic testing
  • Hepatitis B: Surface antigen (HBsAg) testing

Additional Tests Based on Risk Assessment

  • Bacterial vaginosis: For women with symptoms or risk factors
  • Trichomoniasis: For women with symptoms
  • Herpes simplex virus: For patients with genital ulcers
  • Hepatitis C: For patients with risk factors (injection drug use, etc.)

Risk Assessment Questions

When a patient requests STD testing, the following questions should be asked to determine appropriate testing 1:

  1. Sexual history:

    • Number and gender of recent sexual partners
    • Types of sexual contact (oral, vaginal, anal)
    • Use of protection (condoms, dental dams)
    • History of previous STDs

  2. Risk factors:

    • New or multiple sexual partners
    • Partners with known STDs
    • Injection drug use
    • Sex work or partners who engage in sex work
    • Men who have sex with men

  3. Symptoms assessment:

    • Genital discharge, lesions, or rash
    • Dysuria (painful urination)
    • Pelvic or abdominal pain
    • Abnormal vaginal bleeding
    • Testicular pain or swelling

Special Considerations for High-Risk Groups

Men Who Have Sex With Men (MSM)

  • Extragenital testing is crucial - rectal and pharyngeal specimens should be collected for gonorrhea and chlamydia 2
  • Testing positivity rates are significant (3.0%-9.8%) even in asymptomatic patients 2

Pregnant Women

Pregnant women require comprehensive screening due to potential fetal impacts 1:

  • Syphilis testing in early pregnancy and possibly third trimester
  • Hepatitis B testing at first prenatal visit
  • Chlamydia and gonorrhea testing, especially for women under 25 or with risk factors
  • HIV testing at first prenatal visit
  • Bacterial vaginosis testing for those at risk for preterm labor

Common Pitfalls in STD Testing

  1. Inadequate site sampling: Failing to test extragenital sites (rectal, pharyngeal) in MSM leads to missed infections 2

  2. Overlooking asymptomatic infections: Many STDs present without symptoms but remain transmissible and can cause complications

  3. Inadequate follow-up testing: Patients with positive chlamydia should be retested 3 months after treatment to check for reinfection

  4. Not addressing partner notification: All patients with STDs should be counseled about notifying partners for testing and treatment 1

  5. Missing reportable diseases: Providers must be aware that syphilis, gonorrhea, and HIV/AIDS are reportable in all states, while chlamydia is reportable in most states 1

By following these comprehensive testing guidelines, providers can effectively screen for and treat STDs, reducing transmission and preventing long-term complications that affect morbidity, mortality, and quality of life.
