or viam . visual inspection with lugol’s iodine vili also known as schiller’s test uses lugol’s iodine instead of acetic acid. slide overview this is a partial list of the types of vision based tests available for testing for cervical cancer or precancer. the key differences in these tests are whether or not magnification is used and whether acetic acid or some other technique of highlighting abnormalities is used. note for after last bullet this talk focuses on via which has also been referred to as cervicoscopy or direct visual inspection dvi . what does via involve performing a vaginal speculum exam during which a health care provider applies dilute ۳ ۵ acetic acid vinegar to the cervix. abnormal tissue temporarily appears white when exposed to vinegar. viewing the cervix with the naked eye to identify color changes on the cervix. determining whether the test result is positive or negative for possible precancerous lesions or cancer. slide overview via is a relatively simple procedure. note for bullet ۱ acetic acid is used to enhance and mark the acetowhite change of a precancerous lesion or actual cancer. differences in precancerous cell proteins make the abnormal cells temporarily appear white when exposed to vinegar. note fur bullet ۳ results of the test are available immediately and do not require laboratory support. what infrastructure does via require private exam area examination table trained health professionals adequate light source sterile vaginal speculum new examination gloves or hld surgical gloves large cotton swabs dilute ۳ ۵ acetic acid vinegar

ulcer oozing and or bleeding on touch. slide overview here is an overview of via test result categories and a very general description of the clinical findings for each. after discussion of the table training manuals including classification tables with more detailed descriptions are available to help providers differentiate between the three generally used test result categories. categories for via tests results acetowhite area far from squamocolumnar junction scj and not touching it is insignificant. acetowhite area adjacent to scj is significant. negative positive photo source jhpiego slide overview the location of the acetowhite area needs to be considered in the final judgment call as whitish areas representing metaplasia or other things may make assessment of acetowhite changes more challenging. note for bullet ۱ the squamocolumnar junction scj is the point at which columnar cells meet ectocervical squamous cells on the cervix. this junction marks the furthest extent of the transformation zone towards or in the case of post menopausal women into the cervical canal. whitish areas far from the scj are more likely to be metaplasia or warty lesions the woman should not be considered test positive. note for bullet ۲ acetowhite areas that are present on abutting or immediately adjacent to the scj are more likely to be precancerous the woman should be considered test positive. categories for via tests results suspicious for cancer photo source paho jose jeronimo slide overview this imageshows a via test result that is suspicious for cancer. management options what
