Final answer:
Women younger than 30 with an ASCUS cytological result should undergo reflex HPV testing, and based on those results, either receive a colposcopy if positive for high-risk HPV or repeat Pap smear in three years if negative.
Step-by-step explanation:
Women younger than 30 who receive an ASCUS (Atypical Squamous Cells of Undetermined Significance) cytological diagnosis should be managed according to current medical guidelines. Following an ASCUS result, it is recommended to perform reflex HPV testing. If HPV testing is positive for high-risk types, the individual should undergo colposcopy. If HPV testing is negative, it is advisable to repeat Pap smear screening in three years. Women under 30 are less likely to have HPV infections that persist and more likely to clear the virus naturally, emphasizing the importance of HPV testing post-ASCUS results to guide appropriate management.
