Need proof of immunity for your I-693 immigration exam?
This Immigration Titer Panel includes key blood tests used to verify immunity when vaccination records are missing—helping support your USCIS medical exam (Form I-693).

✔ Verify immunity without repeat vaccinations

✔ Helps prepare documentation for Civil Surgeon exam

What This Panel Includes

This basic immigration panel (blood testing only) includes:

MMR Titers

Measles, Mumps, Rubella IgG (Quantitative)
Confirms immunity to all three viruses

Varicella (Chickenpox) Titer

Varicella IgG
Confirms immunity to chickenpox

Hepatitis B Titer

Hepatitis B Surface Antibody (Anti-HBs IgG)
Confirms immunity to Hepatitis B

TB Blood Test (IGRA)

QuantiFERON®-TB Gold
Screens for latent and active tuberculosis

📌 All titers are quantitative whenever applicable, providing numeric antibody levels with reference ranges

Why This Panel Matters for Immigration (I-693)

U.S. immigration law requires vaccination or proof of immunity for:

• Measles
• Mumps
• Rubella
• Varicella (Chickenpox)
• Hepatitis B

👉 If you do not have vaccination records, titers can help demonstrate immunity without repeating vaccines.

Why Choose TB Blood Testing (IGRA)?

Many individuals born outside the U.S. received the BCG vaccine, which can affect TB skin test results. TB blood test is required by the USCIS. TB skin tests are not acceptable.

The TB blood test (IGRA):

✅ Not affected by BCG vaccination
✅ No false positives from prior BCG vaccine
✅ Preferred method for accurate TB screening
✅ Requires only one visit
