What should you know about a COVID-19 check?

A clinician may ask when your illness started, whether you have cough, fever, fatigue, headache or a general feeling of being unwell, and whether you have been near someone with an infection. A home or clinic test may be useful, but a result must be interpreted with the timing of symptoms and the test used. No single question can diagnose COVID-19.

The check also considers your breathing and medical background. Older age, pregnancy, long-term illness or reduced immunity can change how quickly you should seek advice. If symptoms persist after the initial illness, your clinician may consider several explanations, including Long COVID, rather than assuming one cause.

Write down symptom onset, medicines, relevant conditions and any exposure before contacting a healthcare service. Follow local instructions for testing and avoid close contact while you feel unwell. Rest and take fluids regularly. If a clinician recommends a test, follow the collection and result instructions carefully, then ask what to do if the result does not match how you feel.

Do not wait for routine testing if you have severe breathlessness, chest pain, confusion, blue or grey lips, fainting or difficulty staying awake. Seek prompt advice for worsening cough, persistent fever, repeated vomiting, dehydration or a clear decline after temporary improvement. Emergency services can guide you when breathing or alertness changes suddenly.

Ask which test is suitable, when to take it, how to interpret the result and whether anyone at home needs extra protection. Ask which symptoms warrant review and whether your existing medicines or conditions alter your plan.
