COVID-19 testing remains important for international travelers, with many destinations still requiring negative test results for entry or return flights. PCR tests detect the virus's genetic material and are considered the gold standard for accuracy but typically take 24-48 hours for results. Antigen tests identify viral proteins and provide results within 15-30 minutes but may be less sensitive for asymptomatic cases. Antibody tests determine past infection or vaccination response by detecting COVID-19 antibodies in the blood. Testing is particularly important if you've been exposed to someone with COVID-19 or are experiencing symptoms like fever, cough, or loss of taste/smell. Mexico offers testing at competitive prices, often with same-day results at major tourist destinations to accommodate travel requirements.
