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.

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.

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 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 lipid panel is the blood test that measures your cholesterol. It reads several blood fats, including the good and bad kinds and your triglycerides. Together they help a doctor judge your heart risk. A cholesterol test has traditionally asked for a fast, and our on-site lab gives same-day results for most panels.

A thyroid test is a simple blood test that checks the small gland in your neck that sets your energy and weight. If you feel tired, cold, or are gaining weight for no clear reason, a thyroid test can show whether the gland is slow. We run the test on site and explain your results.

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.

A vitamin D test is a simple blood test that checks how much vitamin D is stored in your body. Many expats in Koh Samui are low, even in this sunny place. Indoor work, sunscreen, and staying in the shade all block the sun your skin needs. A quick vitamin D test in Koh Samui gives you an answer the same day.

An iron and anemia panel is a group of blood tests that check if you have enough healthy red blood cells and enough iron to make them. It is one of the first tests a doctor orders for long-lasting tiredness. An iron and anemia panel in Koh Samui uses a small blood sample, with same-day results from our on-site lab.

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.
