Step 2 Identifying abnormal items through trend analysis
→
Step 3 Not knowing which department to visit or when after discovering abnormal findings

Problem

45% of people in their 50s who receive abnormal findings on health checkups never follow up with detailed examinations (NHIS 2024 statistics). Even after getting a result like 'Findings: Abnormal liver function,' they don't know which department to visit (gastroenterology? hepatobiliary surgery?), how much the detailed exam costs, whether national health insurance covers it, or by when they should go. As a result, they miss early detection opportunities and discover worsened conditions at the next year's checkup.

Solution

(1) Enter abnormal checkup findings to get a breakdown of required follow-up exams by item, which department to visit, estimated cost (with national insurance coverage), and recommended deadline, (2) auto-generate a 90-day follow-up calendar (schedule exam → review results → lifestyle adjustment), and (3) send email/push reminder notifications for follow-up actions — all as a web service.

Target: Ages 45-60, with 1+ abnormal findings on health checkup, currently delaying follow-up exams
Revenue Model: Basic guidance and calendar free. Personalized health management plan (3-month) at $7.50 (~9,900 KRW). Referral booking to specialized checkup clinics.
Ecosystem Role: Regulation
