Bladder Cancer, FISH
Test Code10107
CPT Codes
88120 or 88121 depending on method performed.
Preferred Specimen
50 mL voided urine collected in PreservCyt®, CytoLyt®, or ethanol 50%
Minimum Volume
33 mL
Other Acceptable Specimens
Bladder washing collected in a sterile leak-proof PreservCyt, CytoLyt, or ethanol 50%
Instructions
Urine: A urine preservative transport kit, with handling instructions, is available upon request. Perform urine collection (50 mL) at the physician's office or Patient Service Center (PSC) in a sterile 100 mL urine specimen container. Mix voided urine with PreservCyt, CytoLyt, or ethanol 50% in a 1:1 solution. Alternatively, mix urine with preservative Carbowax™ (2% polyethylene glycol in 50% ethanol) 2:1 (v:v).
Bladder washings: Perform bladder washing collection (50 mL) at the physician's office in a sterile 100 mL urine specimen container. Mix bladder washing with PreservCyt, CytoLyt, or ethanol 50% in a 1:1 solution. Alternatively, mix bladder washing with preservative Carbowax (2% polyethylene glycol in 50% ethanol) 2:1(v:v).
It is recommended that specimens be processed within 72 hours of collection. Samples received without preservative will be assayed; any study under these conditions yielding insufficient cells or an abnormal result should have a follow-up study with urine in a preservative. Cold packs are recommended during transportation. If bladder washing is not shipped immediately after collection, refrigerate immediately (Do Not Freeze). Under no circumstances should bladder-washing specimens be stored or shipped at temperatures at or above 37° C.
