A comprehensive health checkup — sometimes called a "health screening" or "annual physical" — is one of the best things you can do for your long-term health. For expats and foreigners living in Busan, it can be especially useful: many chronic conditions (high blood pressure, elevated cholesterol, early diabetes, fatty liver) have no symptoms until they cause real problems, and catching them early makes a big difference.
This guide covers what is included in the comprehensive health checkup at Kim Joo-in Internal Medicine Clinic in Seomyeon, Busan, and what to expect on the day of your visit.
Why get a health checkup?
The main purpose of a health checkup is to catch problems before they become problems. Most adult health issues develop silently over years. High blood pressure usually causes no symptoms. Early diabetes causes no symptoms. Fatty liver causes no symptoms. High cholesterol causes no symptoms. But each of these, left unchecked, eventually causes serious damage to the heart, brain, kidneys, or other organs.
A checkup lets you find out where you stand now, so that if something is off, you can take action while the fix is still easy.
What's included at Kim Joo-in Clinic
The clinic offers the tests listed below, which can be combined in a comprehensive checkup depending on your needs. The exact combination is decided during your consultation.
1. Blood tests
Blood tests can reveal a wide range of conditions in a single draw. Typical panels evaluate:
- Blood cell counts (red cells, white cells, platelets)
- Blood glucose and HbA1c (for diabetes screening)
- Cholesterol profile — total, LDL, HDL, triglycerides
- Liver function (AST, ALT, gamma-GT, bilirubin)
- Kidney function (creatinine, BUN, eGFR)
- Thyroid function (TSH, T3, T4)
- Inflammation markers
2. Urine test
A simple urine test screens for early kidney problems, urinary tract infection, and abnormalities that point toward diabetes or other conditions.
3. Pulmonary function test
Especially useful if you smoke, have a history of respiratory symptoms, or are simply older than 40. The test identifies asthma, COPD, and other lung problems before they cause obvious symptoms. See our guide to pulmonary function testing for details.
4. Chest X-ray
A chest X-ray is a quick, non-invasive way to screen for pneumonia, tuberculosis, and other lung or chest abnormalities.
5. Electrocardiogram (ECG)
The ECG records the electrical activity of your heart and can detect arrhythmias, signs of past heart attacks, and other cardiac abnormalities.
6. Ultrasound imaging
The clinic offers ultrasound in three areas:
- Abdominal ultrasound — evaluates the liver, gallbladder, pancreas, kidneys, and spleen. Common findings include fatty liver, gallstones, kidney cysts, and other silent problems.
- Cardiac ultrasound (echocardiography) — evaluates the structure and function of the heart, including valves and chamber sizes. Often done together with ECG.
- Thyroid ultrasound — screens for thyroid nodules, enlargement, and other abnormalities.
7. Gastroscopy (upper endoscopy)
Gastroscopy is used to examine the esophagus, stomach, and the first part of the small intestine. It is particularly important for screening stomach cancer, which is more common in Korea than in many Western countries.
8. Allergy testing
If you have been having recurring respiratory symptoms, skin reactions, or other unexplained issues, allergy testing can be added. See our guide to allergy skin prick testing for details.
9. Bone density test
Recommended for older adults, especially post-menopausal women, to screen for osteoporosis.
How to prepare
Here are the standard preparation steps for a comprehensive checkup:
- Fast starting the night before. No food or drinks other than water for at least 8 hours before your appointment. This is important for accurate blood sugar, cholesterol, and liver function results.
- If you have a gastroscopy scheduled, fast completely after 10 PM the night before — no food or water. Follow the specific instructions the clinic gives you.
- Take your regular medications as usual unless the doctor specifically tells you to hold them. For blood pressure and other important daily medications, the doctor will typically have you take them with a small sip of water.
- Avoid alcohol for at least 24 hours before the checkup.
- Avoid intense exercise the day before.
- Wear comfortable, loose clothing.
- Bring your ARC (Alien Registration Card) or passport, and your NHIS card if you have one.
- Bring a list of your current medications and any relevant medical history.
What the visit looks like
A typical comprehensive checkup at Kim Joo-in Clinic follows roughly this order:
- Registration and consultation. Fill out a brief form, discuss your concerns and goals for the checkup with Dr. Kim in English.
- Blood and urine samples. Quick and straightforward.
- Vital signs. Blood pressure, pulse, height, weight.
- Chest X-ray.
- ECG.
- Pulmonary function test.
- Ultrasound imaging of whichever areas are included in your package.
- Gastroscopy, if scheduled.
- Follow-up consultation to discuss any same-day findings and plan for any additional test results that need more time (blood work, biopsies, etc.).
Not every test is done for every patient — the combination depends on your age, risk factors, symptoms, and goals. Dr. Kim will recommend a plan based on your consultation.
Getting the results
Some results are available the same day (blood pressure, ECG, ultrasound findings, chest X-ray review). Others take a few days:
- Blood and urine test results: typically 1-2 business days
- Gastroscopy biopsy results (if taken): 5-10 business days
- Allergy blood test results: a couple of days
You will have a follow-up review with Dr. Kim to discuss all findings, explain what they mean for your health, and lay out next steps if any.
Why do your checkup at an English-speaking clinic?
A comprehensive checkup produces a lot of data, and the value of that data depends on how well it is explained. It is one thing to receive a report in Korean with numbers and arrows next to each line — it is another thing to sit with a doctor who speaks your language and walks you through each finding: what is normal, what is borderline, what actually matters, and what you should do about it. That is exactly what Dr. Kim Joo-in provides, in professional English, with 14 years of university hospital experience behind every interpretation.

Frequently Asked Questions
Do I need an appointment for a comprehensive health checkup?
For a comprehensive checkup involving gastroscopy or multiple tests, it is best to call ahead (051-802-7550) so the clinic can plan your visit and give you specific preparation instructions. Regular consultations and simpler tests do not require an appointment.
Do I need to fast before a comprehensive checkup?
Yes. Fast for at least 8 hours before the checkup (no food or drinks except water) for accurate blood sugar, cholesterol, and liver function results. If a gastroscopy is included, fast completely after 10 PM the night before. Follow the specific instructions the clinic provides.
What tests are included in the checkup?
The clinic offers blood and urine tests, pulmonary function test, chest X-ray, ECG, abdominal/cardiac/thyroid ultrasound, gastroscopy, allergy testing, and bone density testing. The exact combination depends on your age, symptoms, and goals. Dr. Kim will recommend a plan during your consultation.
How long does the full checkup take?
It depends on which tests are included. A basic checkup (blood/urine, X-ray, ECG, consultation) is typically 1-2 hours. Adding gastroscopy and multiple ultrasound scans may take 2-3 hours. Results for blood work and biopsies come later, over 1-10 days depending on the test.
