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.

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 testosterone and hormone panel is a blood test that measures the main male hormones, including testosterone. Doctors order it when a man has low energy, low sex drive, mood changes, or trouble building strength. A testosterone test in Koh Samui uses a morning blood sample, since levels are highest early in the day, with same-day results.

A cortisol test is a blood test that measures your main stress hormone. Doctors use it when tiredness, weight changes, or mood problems do not add up, to check if your body is making too much or too little cortisol. A cortisol test in Koh Samui is best taken in the morning, when the hormone naturally peaks, with same-day results.

An allergy panel is a blood test that checks how your body reacts to common triggers like dust, pollen, pet fur, mold, and certain foods. It helps find what is behind your sneezing, rashes, or itchy eyes. An allergy panel in Koh Samui uses one blood sample, so there are no scratches or needles under the skin, with results reviewed by a doctor.

Blood tests in Koh Samui are quick and easy at a private clinic. Our on-site lab runs common panels and gives same-day results for most of them. There are no waiting lists. You see a doctor, give a small blood sample, and get your results explained the same day, often within hours.
