How we see it

There is a set order
for finding the cause.

The same cough can have many causes. What you check first changes the outcome. Testing → reading → treatment → maintenance all continue inside one building.

01History · Exam

We ask when the symptoms began and about your living environment.

02Detailed tests

We look at allergens, lung function and immune markers together.

03Reading the cause

We bring the test results together and explain what the cause is.

04Tailored treatment

Medication and immunotherapy, with Korean Medicine when needed.

05Maintenance

We manage recurrence in step with the seasons and your environment.

The same cough,
but the cause can be different.

Frequently asked questions

What people ask most
before a visit.

For questions not covered here, you can also call us at +82-2-2222-4888.

QHow long should a cough last before I get tested?+
Three weeks is the benchmark. A cough from a cold usually settles within two weeks. Beyond three weeks, other causes such as asthma, postnasal drip from allergic rhinitis and gastroesophageal reflux need to be checked.
QIs allergy testing just one blood test?+
Allergens are identified with skin prick tests and blood tests, and the airways are assessed separately with lung function tests. We select only the items your symptoms call for.
QHow long does immunotherapy take?+
When the causative allergen is clear, it runs over 3–5 years. Before starting, we explain the duration and the likelihood of response.
QIs collaborative care with Korean Medicine available?+
Yes. The Korean Medicine Center is on the 6th floor of the same building, and if reduced immunity is confirmed, Korean medicine treatment is added to the plan.

Before controlling the symptom,
get the cause right.
