As part of Pathology Laboratories, Inc.’s (PathLabs) continuous dedication to providing quality results and assure optimal cytology specimens, all Routine Non-Gynecologic fluids (e.g., urine for cytology and sputum) must be submitted in ThinPrep® CytoLyt® Solution. The ThinPrep® CytoLyt® Solution is a water-based, buffered cell wash solution designed to lyse red blood cells, prevent protein precipitation, dissolve mucus and preserve the morphology of the cellular material. When all Routine Non-Gynecologic fluids (e.g., urine for cytology and sputum) are placed in ThinPrep® CytoLyt® Solution, the specimen cellular material is properly preserved.
