What Tropical Screen (from 6 weeks post-travel) measures
Tropical Screen (from 6 weeks post-travel) is most often requested in connection with infectious diseases, travel-related illness and post-vacation health check, which is why it sits within the tropical and travel medicine group at Wimpole Street.
Travel-related tests look for infections acquired abroad: blood films and antibodies for malaria, serology or PCR for dengue, Zika, chikungunya and other arboviruses, and antibody or urine tests for schistosomiasis (bilharzia), filaria, leishmania, trypanosomes and other parasites. Post-travel screens combine the most common of these with a full blood count, liver tests and stool parasite examination, timed either within six weeks of return or afterwards once antibodies have had time to develop. A pre-travel DVT screen checks clotting factors before long-haul flights in people with risk factors.
Who considers Tropical Screen (from 6 weeks post-travel)
- People often consider these tests if they develop fever, chills or unusual tiredness within weeks of returning from the tropics.
- Swimming in freshwater lakes in Africa or Asia is a recognised reason to screen for schistosomiasis some weeks later.
- Those who have lived or volunteered abroad for extended periods frequently want a comprehensive post-travel check.
- Persistent diarrhoea, itching or an eosinophilia on a blood count after travel are common prompts.
- Some travellers arrange a pre-travel thrombosis risk assessment before very long flights.
Preparing for your Tropical Screen (from 6 weeks post-travel)
- 1Bring a list of countries visited, dates, activities (freshwater swimming, rural stays) and any anti-malarial medication taken.
- 2For antibody-based screens, wait at least six weeks after leaving the risk area, since earlier samples can be falsely negative.
- 3Fever after travel should not wait for a scheduled appointment — see the urgent guidance on this page.
- 4Stool samples for parasites are often requested as three separate specimens on different days.
Sample for this test: venous blood sample (serum).
Understanding your Tropical Screen (from 6 weeks post-travel) results
A positive malaria film or antigen indicates active infection and is treated as an emergency; antibody tests, by contrast, show past exposure and are not used for acute diagnosis. Positive schistosome or filarial antibodies can indicate infection acquired months or years ago and are usually followed by specific treatment or further tests. Arbovirus serology often cross-reacts between related viruses, so a positive dengue or Zika antibody may need confirmatory testing.
Travel infection tests are highly dependent on timing since exposure and on the region visited, so results are interpreted with a detailed travel history.
Fever within three months of visiting a malaria region can be a medical emergency. Do not wait for a booked appointment — call NHS 111 or go to an emergency department the same day and say where you have travelled.
