STD Expanded Panel
Test Overview
The STD Expanded Panel is a comprehensive diagnostic tool designed to detect a wide range of sexually transmitted infections (STIs). This panel combines molecular testing (PCR), immunoassays, and culture methods to ensure precise and accurate detection. It is ideal for individuals seeking a thorough STI screening for peace of mind or due to concerning symptoms.
Conditions and Pathogens Detected
Bacterial Infections:
- Chlamydia trachomatis – Common cause of genital infections
- Neisseria gonorrhoeae – Causes gonorrhea
- Mycoplasma genitalium – Linked to persistent urethritis and cervicitis
- Ureaplasma urealyticum – Often found in genital infections
- Treponema pallidum (Syphilis) – Detects active syphilis infection
Viral Infections:
- Herpes Simplex Virus 1 (HSV-1) – Can cause oral and genital sores
- Herpes Simplex Virus 2 (HSV-2) – Commonly associated with genital herpes
- Human Papillomavirus (HPV) – Identifies high-risk strains linked to cervical and other cancers
- Human Immunodeficiency Virus (HIV-1 & HIV-2) – Screens for both types of HIV
- Hepatitis B Virus (HBV) – Identifies chronic or acute hepatitis B infection
- Hepatitis C Virus (HCV) – Detects hepatitis C infection
Parasitic Infection:
- Trichomonas vaginalis – Common STI that causes irritation and discharge
Symptoms That May Require This Panel
- Unusual genital discharge
- Burning sensation during urination
- Genital sores, ulcers, or irritation
- Pelvic pain or discomfort
- Painful intercourse
- Swollen lymph nodes in the groin
- Flu-like symptoms (fever, fatigue, body aches)
- Abnormal vaginal bleeding or spotting
Sample Collection
- Sample Type:
- Urine sample (preferred for bacterial STIs)
- Genital swab (for higher accuracy with some infections)
- Blood sample (for viral infections like HIV, HBV, and HCV)
- Container: Sterile urine collection cup, swab with transport medium, or blood vial
- Collection Tips: Avoid urinating for at least 1 hour before urine sample collection. For swabs, ensure thorough sample collection from the appropriate site
Result Interpretation
| Test Component: | Normal (Negative): | Abnormal (Positive): |
|---|---|---|
| Chlamydia trachomatis | Not Detected | Detected – Confirms Chlamydia infection |
| Neisseria gonorrhoeae | Not Detected | Detected – Confirms Gonorrhea |
| Mycoplasma genitalium | Not Detected | Detected – May indicate persistent urethritis |
| Treponema pallidum (Syphilis) | Not Detected | Detected – Confirms Syphilis |
| Herpes Simplex Virus 1 (HSV-1) | Not Detected | Detected – Confirms HSV-1 |
| Herpes Simplex Virus 2 (HSV-2) | Not Detected | Detected – Confirms HSV-2 |
| Trichomonas vaginalis | Not Detected | Detected – Confirms Trichomoniasis |
| HIV-1 & HIV-2 | Negative | Positive – Requires confirmatory testing |
| Hepatitis B Virus (HBV) | Negative | Positive – Indicates active or chronic HBV infection |
| Hepatitis C Virus (HCV) | Negative | Positive – Confirms HCV infection |
Treatment Guidance Based on Results:
- Chlamydia / Gonorrhea / Mycoplasma → Antibiotic therapy (Azithromycin, Doxycycline, or Ceftriaxone)
- Syphilis (Treponema pallidum) → Penicillin G (First-line treatment)
- HSV-1 / HSV-2 → Antiviral therapy (Acyclovir, Valacyclovir)
- HIV → Immediate referral to an HIV specialist for antiviral treatment
- Hepatitis B / C → Specialized antiviral treatment plans
Turnaround Time
- PCR Results: 24–48 hours
- HIV / Hepatitis Serology: 2–5 days
