Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
This test is designed to hold the sample and delay fluorescence in situ hybridization (FISH) testing while preliminary morphologic assessment or flow cytometry testing is in process.
Hold policy: Upon sample receipt, the specimen will be held in the laboratory. FISH testing will not be performed unless the client contacts the laboratory and indicates that FISH testing is desired. The client must contact the Cytogenetics Laboratory at 800-533-1710 by 4 p.m. (central time) no later than 4 business days (96 hours) after the specimen was collected. If no notification is received by this time, the order will be processed as "cancelled". Weekend communication can be deferred until Monday.
