Lab data

Patient is from (state withheld) and received vaccines at Medical Center. Our clinic is attempted to obtain vaccine records but we were noted father had to sign their HIPPA form either thru online database or in person at their clinic. Father was unable to do it through online database and wanted to vaccinate patient for school. Serology testing for Varicella was done, which showed patient was not immune to Varicella, and thus Varicella vaccine was given.
