The green-card medical exam (Form I-693) must be performed by a USCIS-designated civil surgeon — no direct-to-consumer test replaces it. What this panel does is let you walk in prepared: it screens the same infectious-disease markers the civil surgeon will test, weeks before your appointment. A positive TB blood test discovered AT the exam means chest X-rays, possible latent-TB treatment, and months of delay at the worst possible moment; discovering it early means you can start any needed follow-up on your own schedule. The panel includes the QuantiFERON-TB Gold Plus blood test (the modern TB test that is not affected by BCG vaccination, which most immigrants received), syphilis screening with automatic confirmatory testing, and urine-based gonorrhea/chlamydia screening — the same test types listed in the CDC's Technical Instructions for civil surgeons. Results are CLIA-certified and yours to keep.
Pre-screens the infectious-disease markers evaluated at the USCIS civil-surgeon medical exam (tuberculosis via IGRA blood test, syphilis with reflex confirmation, gonorrhea/chlamydia) so applicants can identify and address issues weeks before their I-693 appointment. Does not replace the civil-surgeon exam.
Green-card and adjustment-of-status applicants who want to know their TB and STI screening status before the official civil-surgeon exam — especially anyone BCG-vaccinated who has previously had a positive TB skin test.

The short answer
Worth it if a surprise result would hurt your immigration timeline - which is exactly what a positive TB test discovered AT the civil-surgeon exam does. This panel screens the same three lab markers the I-693 exam checks (TB, syphilis, gonorrhea) weeks ahead, for less than the cost of a second civil-surgeon visit. It does not replace the exam.
We would rather you order the right test than the most expensive one.
This is a walk-in visit: a venous blood draw (TB + syphilis) plus a urine sample (gonorrhea/chlamydia) at Labcorp, or BioReference for NY/NJ. Don't urinate for at least an hour before your visit so the urine portion is valid. No fasting. One visit covers all three markers.
An at-home draw is not recommended for this test — it needs a lab-based collection to be accurate.
The markers that matter most and what an out-of-range value can mean. Reference ranges vary by lab, age and sex.
| Marker | Typical range | What it means |
|---|---|---|
| QuantiFERON-TB Gold Plus | Negative | Positive means TB exposure (not active disease) - the finding that delays I-693s when discovered late. Early discovery means a chest X-ray and, for latent TB, a short treatment course on your schedule. |
| Syphilis RPR (with reflex confirmation) | Non-reactive | Reactive screens are automatically confirmed with treponemal testing. Confirmed syphilis is treatable with antibiotics; treated and documented infection does not make you inadmissible. |
| Chlamydia / Gonorrhea RNA (urine) | Not detected | Both are often symptomless and both are curable with antibiotics. The exam screens gonorrhea for applicants 18-24; knowing beforehand means treating beforehand. |

No — and be wary of anyone who says otherwise. The I-693 exam can only be performed by a USCIS-designated civil surgeon, who orders their own testing as part of the exam. What this panel does is screen the same markers in advance, so a surprise (like a positive TB blood test) doesn't derail your green-card timeline at the appointment. You can also share your results with your civil surgeon.
Per the CDC's Technical Instructions, civil surgeons test applicants for tuberculosis using an IGRA blood test (QuantiFERON) for ages 2 and up, screen for syphilis (ages 18-44), and screen for gonorrhea (ages 18-24), plus review vaccination records. This panel covers all three lab markers.
A positive TB blood test discovered at the exam typically means a chest X-ray, possible latent-TB treatment, and weeks-to-months of delay — discovered at the worst possible time. Around 1 in 4 people worldwide carry latent TB, and it's especially common in many countries immigrants come from. Knowing your status early lets you complete any follow-up on your own schedule, before it can hold up your application.
Not because of BCG. The QuantiFERON blood test in this panel is not affected by prior BCG vaccination, unlike the older skin test (PPD), which frequently reads falsely positive in BCG-vaccinated people. That's exactly why the blood test is the standard for immigration screening — and why it's the right choice if you've had a 'positive' skin test before.
This panel is $159.99 (the three tests ordered separately would be $184.97). Civil-surgeon exams themselves typically run $200-500+, and repeat visits after a surprise finding add more — pre-screening is inexpensive insurance against a delayed application. No insurance or doctor's referral is needed, and HSA/FSA cards are accepted.
No. The I-693 exam can only be performed by a USCIS-designated civil surgeon, who orders their own testing. This panel is pre-screening: the same marker types, run early, so you and your doctor can address anything before the official exam. Bring your results to the appointment - they inform the civil surgeon even though they don't replace their tests.
Per CDC Technical Instructions: an IGRA TB blood test for ages 2+, syphilis serology for ages 18-44, and gonorrhea screening for ages 18-24 - plus a vaccination-record review and physical exam. This panel covers all three lab markers; for the vaccination side, see titer testing.
That is the panel doing its job. Latent TB means a chest X-ray and a 3-4 month preventive antibiotic course; syphilis, gonorrhea, and chlamydia are curable with antibiotics. None of these findings, treated and documented, makes you inadmissible - they only cause delays when they surface mid-application. Positive results deserve a prompt conversation with a healthcare provider.
The panel is $159.99; ordering the three tests separately would be $184.97. Civil surgeons typically charge $200-500+ for the exam, and a surprise finding usually means paying for a follow-up visit. Pre-screening is the cheap half of the process - and the only half you can control the timing of.
Immigration Exam Prep Panel results are typically ready in 3–5 business days after your draw at Quest or Labcorp. TestWell emails you the moment they post, and your results dashboard shows each marker against its reference range with a plain-English explanation.
No, fasting is not required for an Immigration Exam Prep Panel — you can eat normally and book any time of day. Do not urinate for at least 1 hour before your lab visit — a urine sample is collected for the gonorrhea/chlamydia portion.
