DMV Campus TB (QuantiFERON vs PPD) & Titer Checker
Skip Skin PPD: Draw QuantiFERON-TB Gold (IGRA) Single-Visit Blood Test
Prior childhood BCG immunization triggers frequent false-positive skin indurations on a PPD test, forcing expensive Chest X-ray follow-ups and delaying registration holds. UMD accepts QuantiFERON-TB Gold directly to clear myuhc.umd.edu in one visit.
Closest TB Screening & Campus Compliance Lab
1. QuantiFERON-TB Gold vs Skin PPD Matrix
University immunization portals lock class registration within weeks of add/drop deadlines if translated childhood records lack exact dates or show an unverified TB skin test. Selecting the right test first prevents repeat clinic visits.
| TB Screening Method | Clinic Trips Needed | BCG Accuracy & Campus Verdict |
|---|---|---|
| QuantiFERON-TB Gold / T-Spot (IGRA) | 1 Blood Draw Visit | Zero BCG Cross-Reaction | Gold Standard |
| 1-Step Mantoux PPD Skin Test | 2 Visits (48-72h Window) | High BCG False Positives -> Forces Chest X-Ray |
| Quantitative MMR/HepB/Varicella Titers | 1 Lab Blood Draw | Replaces Missing Overseas Childhood Records |
2. Portal Deadlines & Clinical Rotation Redlines
Incoming Terps must submit the online TB questionnaire inside myuhc.umd.edu; UMD Health Center (301-314-8114) specifies IGRA blood testing when any TB risk trigger is answered yes.
Clinical rotations (MedStar, INOVA, Johns Hopkins) reject qualitative "Immune" summaries lacking numerical values (e.g., HBsAb >= 10 mIU/mL).
University registrars routinely reject smartphone photos of handwritten vaccination booklets lacking clinic stamps, exact day-month-year dates, or provider signatures.
Combining Yellow Fever & Campus Onboarding in One UMD Visit
Fellowship & Study Abroad Sync: University of Maryland Health Center sits on campus in College Park (20742) and handles both student immunization compliance and public-access CDC Yellow Fever ($200) + travel consultations.
Off-Campus MinuteClinic & LabCorp Option: When campus health appointment slots fill before orientation week, CVS MinuteClinics across Bethesda, Silver Spring, and D.C. issue lab requisitions for QuantiFERON-TB Gold drawn at Quest or LabCorp.
