* Requirement
  r.t. = room temperature; fridge = 4-8oC (household refrigerator, lower compartment)
frozen = -10oC or less (household freezer, upper compartment)
ThinPrep and SurePath cell suspensions are stable > 2 weeks for cytology at room temperature. But do not keep them for more than
       3 days for DNA testing because it might affect the typing of high risk HPV types; keeping at 4oC or frozen is recommended.
