Abstract:  Objective Toinvestigatetheclinicalvalueofcellsfreeferrousprotoporphyrin
(
FH ) andthin-cytologictest ( TCT ) inthescreeningofcervicallesions.Methods FH wasused
toexamine100patientswhohadbothTCTresultsandpathologicalexaminationresults.Based
ongoldstandardofpathologicalexamination ( >CIN Ⅰ wasdefinedaspositive ), thesensitivity ,
