TL;DR: The results support the use of HPV testing as the sole primary screening test, with cytology reserved for women who test HPV positive, with large demonstration projects needed to fully evaluate this strategy.
Journal ArticleDOI
Human papillomavirus DNA versus Papanicolaou screening tests for cervical cancer.
Marie-Hélène Mayrand,Eliane Duarte-Franco,Isabel Rodrigues,Stephen D. Walter,James A. Hanley,Alex Ferenczy,Sam Ratnam,François Coutlée,Eduardo L. Franco +8 more
TL;DR: HPV testing has greater sensitivity for the detection of cervical intraepithelial neoplasia than Pap testing, and Triage procedures for Pap or HPV testing resulted in fewer referrals for colposcopy than did either test alone but were less sensitive.
Journal ArticleDOI
Sorbitol-MacConkey medium for detection of Escherichia coli O157:H7 associated with hemorrhagic colitis
S B March,Sam Ratnam +1 more
TL;DR: SMAC medium stool culture is a simple, inexpensive, rapid, and reliable means of detecting E. coli O157:H7, and it is recommended routine use of SMAC medium especially for culturing bloody stools.
Journal Article
Human Papillomavirus Testing for Primary Screening of Cervical Cancer Precursors
TL;DR: It is concluded that HPV testing in conjunction with cytology improved the screening efficacy of cytology alone and may allow for a more effective and safe primary screening program with increased screening intervals.
Journal ArticleDOI
The laboratory diagnosis of syphilis.
TL;DR: The present paper discusses the various serological and alternative tests currently available along with their limitations, and relates their results to the likely corresponding clinical stage of the disease.
