Mobile Phlebotomy in San Antonio
For people with limited mobility, anxiety around in-person blood draws, packed schedules, or young kids at home, mobile phlebotomy, an in-home blood draw service, can be a practical fit.

These services send a phlebotomist to your home, and availability or added convenience fees may depend on location and appointment time.
Appointments typically 6:00am–10:00pm, 7 days a week.
- Sample is drawn in your home, not a waiting room
- No travel time to a lab

- Helpful for limited mobility or anyone who prefers privacy
For another option, at-home blood test kits let you collect a finger-prick sample yourself and mail it to a CLIA-certified lab.
