Use Yuljeon Public Parking Lot. We validate 30 minutes for outpatient visits and 1 hour for health screening.
Respiratory & Allergy Care
Is the Aridol bronchial challenge test available?
Yes. If asthma is suspected but routine pulmonary function testing is inconclusive, the doctor may arrange an Aridol (Mannitol) Bronchial Challenge Test to assess airway hyperresponsiveness. Preparation instructions are provided after consultation.
What allergy tests do you offer?
We offer allergy blood testing rather than skin prick testing . Tests are selected according to symptoms and history, including allergic rhinitis, asthma, recurrent cough, and urticaria.
Which tests are used when asthma is suspected?
Depending on symptoms and examination findings, pulmonary function and bronchodilator response tests are performed first. Aridol (mannitol) challenge testing may be added to assess airway hyperresponsiveness.
Health Screening
What health screening options are available?
National general and life-stage screening, screening for stomach, colorectal, liver, breast and cervical cancer, employee screening, comprehensive checkups, and group screening are available.

NHIS awarded the highest rating in Cycle 4 (2021–2023) and an Excellent rating in Cycle 5 (2024–2026). All six categories—general health screening and stomach, colorectal, liver, breast and cervical cancer screening—received Excellent ratings.
When should I stop eating before health screening?
Finish dinner before 20:00 the evening before, then fast. On the morning of the examination, do not eat, drink water, smoke, or chew gum.

When can I eat after endoscopy?
Food is usually permitted 30–60 minutes after the examination, as instructed by the medical team. Start with soft foods. Activity restrictions after sedation or treatment still apply.

Do not stop medicines on your own. Instructions for blood pressure medicines, diabetes medicines, and insulin depend on the examination and its timing. Tell us what you take when booking and follow the medical team’s instructions.
What if I take aspirin or another blood-thinning medicine?
Do not stop aspirin, clopidogrel, warfarin, or a direct oral anticoagulant on your own. Any adjustment depends on the possibility of polypectomy and your risk of thrombosis, and should be discussed with the prescribing medical team.
