Blood Tests in Bang Tao
A fever on day three of a holiday is a different proposition from a fever at home. It could be an ordinary virus that will pass in two days, or it could be dengue, and those two possibilities are managed very differently. Blood tests in Bang Tao are processed in our own on-site laboratory, so most results come back during the same visit rather than tomorrow afternoon.
Tests we run on site
The panels that answer most of the questions a holiday actually raises:
- Dengue rapid test — NS1 antigen and antibodies
- Full blood count, which shows infection patterns and the falling platelets of dengue
- Malaria film, where the travel history calls for it
- Influenza and COVID swabs
- Liver and kidney function
- Blood glucose, HbA1c, cholesterol and thyroid
- Rapid HIV and syphilis
- Inflammatory markers such as CRP
Why a fever here gets a blood test
At home a short fever is usually watched for a few days and that is entirely reasonable. In Phuket that approach misses things that matter.
Dengue is common here, and the moment it is a possibility the management changes — paracetamol only, no ibuprofen and no aspirin, because those affect platelets at exactly the point when dengue is lowering them. A full blood count also distinguishes a bacterial pattern from a viral one, which decides whether antibiotics will help at all.
Getting that answer in half an hour rather than after two days of guessing is the practical argument. See dengue fever and fever treatment.
How long results take
Rapid tests — dengue, HIV, syphilis, influenza, COVID — take about twenty minutes. Full blood counts and basic chemistry usually come back within the hour. More specialised tests are sent to an external laboratory and take one to three days.
You do not have to sit at the clinic waiting for send-out results. We message them to you, and where something needs acting on the doctor telephones rather than leaving you to interpret a column of numbers against reference ranges.
Do you need to fast?
For most tests, no. Come in as you are, particularly if you are unwell — nobody should be starving themselves while running a fever.
Fasting for eight to twelve hours matters for cholesterol and fasting glucose, so a health check up is best booked for the morning before breakfast. Water is not only allowed during a fast but actively helps: dehydration makes the blood draw harder and skews kidney results.
Results that need acting on immediately
Some findings mean we keep you at the clinic rather than sending you back to the hotel:
- Platelets falling in confirmed dengue, which needs monitoring and sometimes admission
- Markers suggesting severe bacterial infection
- Very high blood sugar in an unwell traveller
- Kidney function that has dropped significantly with dehydration
- Haemoglobin low enough to suggest bleeding somewhere
Where a result needs hospital care, we arrange the referral and send the results with you so nobody repeats the tests from scratch and loses another two hours.
Making sense of your own results
You get a printed copy with your values alongside the reference ranges, and the doctor goes through what each one means in plain language rather than handing it over.
Two things are worth understanding before you read them. A single value slightly outside a reference range is very often meaningless — ranges are defined so that a percentage of perfectly healthy people fall outside them by definition. And results move with circumstances: dehydration, a heavy night, hard exercise the day before, and an acute infection all shift numbers temporarily.
The pattern across several results, and the trend over time, matter far more than any one figure. Where something genuinely needs following up, you are told what it is, whether it needs acting on now, and when to repeat the test — either here or with your own doctor at home, since the report is issued in English with standard international ranges.
The blood draw itself
It takes about a minute. A tourniquet goes on the upper arm, the skin is cleaned, and a small needle draws into one or more tubes depending on which tests were ordered. Different coloured tubes contain different preservatives, which is why several may be filled from the same puncture rather than several punctures.
If you faint at blood tests, say so before rather than afterwards — it is common, it is nothing to apologise for, and it is entirely manageable by lying you down for the draw instead of sitting you up. Being well hydrated makes the veins easier to find and the whole thing faster, so drink water beforehand unless you are fasting for glucose, in which case water is still fine and still helps.
Bruising afterwards is normal, particularly on thin skin or if you are on blood thinners. Press firmly on the site for a couple of minutes rather than bending the elbow up, which is the traditional method and the one that produces most of the bruises.
Frequently asked questions
How much do blood tests cost?
Each test is priced separately and a rapid dengue test or full blood count is inexpensive. Larger panels cost more. You are given the price for the specific tests the doctor recommends before any blood is taken.
Can I just ask for a test without seeing a doctor?
You can request specific tests and we will run them. A short consultation first is usually better value, because the doctor may order the test that actually answers your question rather than the one you guessed at.
Can blood be taken at my hotel?
Yes. On a doctor hotel visit the sample is drawn in your room and processed back at the clinic, with results sent to you.
How soon after a mosquito bite can dengue be detected?
The NS1 antigen becomes detectable from about the first day of fever, which is why we test on fever rather than on the bite. Testing before any symptoms appear tells you nothing useful.
Will you explain the results?
Yes, in plain language, and you get a printed copy to keep. That copy is also what your travel insurer will want if you claim.
Are the results accepted by doctors at home?
Yes. Reports are issued in English with standard international reference ranges, so any doctor can read them without translation or conversion.
