In Vitro Testing
  • Low risk for highly sensitive patients
  • Requires little staff time or overhead
  • Allows additional tests at a later date with serum sample
  • Medication suspension not required before testing
  • Ideal for testing food allergy
  • Quantifiable measure
  • Revenue stream in some states where allowed
  • Results available within 3-5 days
