High Quality Service and Rapid Response
City of Hope’s Histocompatibility Laboratory maintains high quality service and rapid response times. With the exception of unique circumstances, we communicate HLA typing results within a maximum of ten (10) working days upon receipt of a blood specimen. Results of histocompatibility testing can be reported by phone, fax or email as soon as they are available, and will be followed by an official written report.
