Diagnostics

An ECG is a quick, painless test that records your heart’s electrical activity through stickers on your skin. It takes about five minutes and shows your heart rhythm and signs of some heart problems. An ECG in Koh Samui is a useful first heart check, but it is a snapshot, so a doctor reads it alongside your symptoms and history.

A liver function test is a blood test that checks how well your liver is working. It measures several markers that can rise when the liver is stressed or inflamed. On the island, heavy drinking is a common reason to test. Our on-site lab runs a liver function test and a doctor explains what your results mean.

A pre-employment or work permit medical is a health check that an employer or Thai visa office asks for before you start a job. It usually includes a doctor’s exam and a set of basic tests, ending in a signed medical certificate. A pre-employment medical in Koh Samui can often be done same-day at our walk-in clinic, with the certificate you need.

A kidney function test is a blood test that shows how well your kidneys filter waste from your body. It checks markers like creatinine and urea, and can estimate your filtering rate. Kidney problems are often silent early on. Our on-site lab runs a kidney function test and a doctor explains what your results mean.

A food allergy is a fast immune reaction that can be dangerous, while a food intolerance is a slower digestive problem that is uncomfortable but not life-threatening. They need different approaches. A food allergy test in Koh Samui uses a blood sample, while intolerances are usually found through a doctor-guided food diary and elimination, not a single blood test.

A full blood count is one of the most common blood tests. It counts your red cells, white cells, and platelets, and measures your haemoglobin. From this one test, a doctor can spot signs of anaemia, infection, and other problems. Our on-site lab runs a full blood count with same-day results for most panels.

An HbA1c is a blood test that shows your average blood sugar over the past three months. Unlike a fasting sugar test, an HbA1c needs no fasting, so you can take it any time of day. Doctors use it to check for diabetes and to track it. Our on-site lab runs an HbA1c with same-day results for most panels.

The dengue NS1 test is a fast blood test that can confirm dengue in the first days of fever, often within an hour at our clinic. It looks for a protein the dengue virus makes early on. On Koh Samui, dengue is a real risk. Our on-site lab runs the NS1 test with quick, same-day results.

H. pylori is a common stomach bug that can cause ulcers and long-term gastritis. An H. pylori test checks whether you carry it, using a breath, stool, or blood sample. If it is found, treatment can clear it. Our clinic runs H. pylori testing and a doctor explains your results and next steps.

A uric acid test is a blood test that helps confirm gout, a painful form of arthritis. Gout happens when uric acid builds up and forms sharp crystals in a joint, often the big toe. The test measures the uric acid in your blood. Our on-site lab runs a uric acid test and a doctor explains your results.
