A fever on the second day of your holiday, vomiting before a flight, or pain when passing urine can quickly turn a planned day in Athens into a medical concern. The right testing options for sick travellers depend on your symptoms, how quickly they started, your medical history and whether you are getting better or worse. A prompt clinical assessment matters more than choosing a test at random.
For many travellers, the priority is simple: speak to an English-speaking doctor, find out what is likely causing the problem and receive treatment without spending hours trying to navigate an unfamiliar healthcare system. Some conditions can be diagnosed during a consultation. Others need rapid testing, laboratory analysis or, occasionally, hospital imaging.
Start with a medical assessment, not a test menu
A test result only becomes useful when it is interpreted alongside your symptoms and examination. A sore throat may be viral, bacterial or related to irritation from air conditioning. Diarrhoea may be caused by a short-lived foodborne illness, a virus, medication or a more serious infection. Testing every possible cause is rarely necessary and can create delays or confusing results.
A doctor will usually ask when your symptoms began, where you have travelled, what you have eaten or drunk, whether anyone around you is unwell, and whether you have existing conditions or regular medication. They may check your temperature, oxygen level, pulse, blood pressure, throat, ears, chest and abdomen before recommending the most appropriate next step.
This approach can save time. If symptoms are mild and clearly improving, supportive treatment and safety-net advice may be all you need. If symptoms are severe, persistent or unusual, testing becomes more urgent.
Common testing options for sick travellers
Rapid tests for respiratory symptoms
If you have fever, cough, sore throat, blocked nose, body aches or sudden fatigue, a rapid test may help identify certain respiratory infections. Depending on your symptoms and local clinical guidance, this can include tests for COVID-19, influenza or streptococcal throat infection.
Results from some rapid tests are available during the consultation, which can help guide immediate decisions about medication, rest, isolation around vulnerable people and whether it is sensible to travel. However, a negative rapid test does not always rule out infection, particularly very early in an illness. Your doctor may advise repeat testing, a laboratory test or reassessment if symptoms continue.
Blood tests when symptoms need a broader answer
Blood testing can be useful when you have persistent fever, marked weakness, dehydration, abdominal pain, suspected infection, an allergic reaction, unexplained dizziness or concerns about inflammation. It may also be needed if you have a chronic condition such as diabetes, kidney disease or a weakened immune system.
Common blood tests can assess signs of infection or inflammation, hydration, kidney function, liver function, blood sugar and electrolytes. Results may be available quickly for urgent cases, while other tests take longer. The key question is whether the result will change your treatment or determine whether you need hospital care.
Urine testing for pain, fever or dehydration
Burning when passing urine, frequent urination, lower abdominal discomfort, back pain or fever can point to a urinary tract infection. A urine dip test can provide useful initial information quickly. In some cases, a urine sample should also be sent for culture to identify the bacteria and confirm which antibiotic is most likely to work.
Urine testing can also help assess dehydration and may be relevant when vomiting, diarrhoea or hot weather has made it difficult to drink enough. Pregnant travellers, men with urinary symptoms, and anyone with fever or flank pain should seek assessment promptly rather than self-treating with leftover antibiotics.
Stool tests for prolonged or severe diarrhoea
Traveller’s diarrhoea often settles with fluids, rest and practical advice. Testing is more likely to be helpful when diarrhoea lasts several days, contains blood, comes with a high fever, follows recent antibiotic use, or is accompanied by significant abdominal pain or dehydration.
A stool test may look for bacteria, parasites or other causes of gastrointestinal illness. Results do not always arrive immediately, so your doctor may treat symptoms and make a clinical decision while awaiting the laboratory report. Do not take anti-diarrhoeal medicines if you have bloody diarrhoea, a high temperature or severe abdominal pain unless a clinician advises it.
Pregnancy, sexual health and other focused tests
Unexpected illness can overlap with other health concerns. A pregnancy test may be appropriate before prescribing certain medicines or investigating abdominal pain, nausea or vaginal bleeding. Sexual health testing may be recommended after a possible exposure, new genital symptoms or pelvic pain.
Tests for allergies, malaria, dengue and other travel-related illnesses are not routine for every unwell visitor. They are considered when your destination history, symptoms and timing make them clinically relevant. Be open about where you have been in the weeks before arriving in Athens, including stopovers, cruises and rural travel.
When imaging or hospital assessment is the safer option
Laboratory tests are not always enough. Severe or localised pain, a suspected fracture, breathing difficulty, chest pain or signs of a surgical problem may require an X-ray, ultrasound, CT scan or specialist review. These investigations are usually arranged through a hospital or diagnostic centre rather than performed at a routine consultation.
A private clinic can assess your condition, stabilise immediate concerns and coordinate with a private hospital where needed. This is particularly valuable if you are travelling alone, do not speak Greek or are unsure which service is appropriate.
Warning signs: do not wait for routine testing
Seek urgent medical help immediately if you have chest pain, severe difficulty breathing, fainting, confusion, a seizure, blue lips, a severe allergic reaction, weakness on one side of the body, sudden speech problems, or uncontrolled bleeding. In Greece, call 112 for an emergency.
You should also arrange same-day medical assessment for a high or persistent fever, severe dehydration, repeated vomiting, bloody diarrhoea, a stiff neck, severe headache, worsening abdominal pain, a painful swollen leg, or symptoms that are rapidly getting worse. Children, pregnant people, older adults and people with significant medical conditions may need earlier assessment even when symptoms appear less dramatic.
Choosing the most practical care option in Athens
If you are well enough to travel, a walk-in consultation can be the fastest route to examination and testing. If leaving your hotel, flat or Airbnb feels difficult, a hotel visit or home visit may be more suitable. Telemedicine can be useful for initial advice, reviewing symptoms, discussing test results and deciding whether in-person examination is necessary.
HOMED Clinic provides 24/7 English-speaking support through walk-in consultations, hotel and home visits, telemedicine, diagnostic testing, prescriptions and coordination with private hospitals. This means you can receive clear advice on whether a rapid test, laboratory test, prescription or urgent referral is the appropriate next step, without guessing.
Bring your passport or identification, travel insurance details if applicable, a list or photo of your regular medicines, and any recent results you have. If you are concerned about an upcoming flight, tell the doctor your departure time. Some tests and treatments can be arranged quickly, but results from specialist laboratory tests may not be ready the same day.
Frequently asked questions
Can I get antibiotics after a test?
Possibly, but antibiotics are not the right treatment for most coughs, colds and many cases of diarrhoea. A clinician may prescribe them when there is evidence or a strong clinical suspicion of a bacterial infection. Taking antibiotics unnecessarily can cause side effects, worsen certain bowel illnesses and make future infections harder to treat.
Will travel insurance cover testing?
Coverage depends on your policy, the reason for testing and whether the condition is considered pre-existing. Keep itemised receipts, medical notes and test reports. If your insurer requires pre-authorisation for hospital treatment, ask for help contacting them before non-emergency admission where possible.
Can I fly if I am unwell?
It depends on the illness. Mild cold symptoms may be manageable, but fever, dehydration, active vomiting, significant diarrhoea, severe ear pain, shortness of breath or suspected contagious infection can make flying unsafe or extremely uncomfortable. A doctor can advise based on your condition and provide medical documentation when appropriate.
Feeling ill abroad is stressful enough. Arrange an assessment early, especially if symptoms are progressing, so you can make a clear decision about testing, treatment and the rest of your stay.
