TB Blood Test vs TB Skin Test for School
Last updated: May 31, 2026
Quick answer
Many schools accept either TB blood testing or TB skin testing, but students should follow their school form. A QuantiFERON TB blood test usually requires one visit, while a TB skin test usually requires a return visit for reading.
Quick comparison
| Test | Typical visit pattern | SchoolTiters option |
|---|---|---|
| TB Blood Test / QuantiFERON | Usually one blood draw visit | QuantiFERON TB Gold Blood Test |
| TB Skin Test / PPD | Usually placement plus return visit for reading | TB Skin Test |
| 2-Step TB Skin Test | Multiple visits | 2-Step TB Skin Test |
Which should you choose?
- Choose what your school form specifically requests.
- If both are accepted, TB blood testing may be simpler because it usually avoids the return visit needed for skin-test reading.
- If your form asks for a TB skin test specifically, order the TB skin test option.
