Post-recovery tests for COVID 19 or severe influenza Dont neglect your health

In many cases, the journey with illness doesn't end once the symptoms disappear—especially after an infection with COVID-19 or a severe flu. Some symptoms may linger, or hidden complications may affect vital organs such as the heart, lungs, or immune system. That’s why it's important to undergo medical tests after recovery to ensure your overall health and detect any underlying issues.In this article from   Dalili Medical, we provide you with a complete guide to the most recommended tests after recovering from strong influenza or COVID-19.

✅ Why Are Post-Recovery Tests Recommended?

Even after feeling better, some viruses—like COVID-19 or severe influenza—can continue to affect your body for weeks or even months. Post-recovery blood tests help:

• Assess heart and lung function

• Detect signs of inflammation or blood clots

• Monitor immune system recovery

• Check liver and kidney function

 Key Medical Tests After COVID-19 or Severe Flu

Here are the most important tests you should consider after recovering:

1. Complete Blood Count (CBC)
What it detects: Anemia, infections, immune cell abnormalities
✅ Useful for evaluating white and red blood cell levels post-illness.

2. C-Reactive Protein (CRP)
What it detects: Levels of inflammation in the body
✅ Indicates if your body is still experiencing an inflammatory response after the virus.

3. D-Dimer
⚠️ Why it's important: Detects blood clot risks, a common complication of COVID-19
✅ Recommended for those who experienced chest pain or shortness of breath.

4. Liver Enzymes (ALT – AST – GGT)
What it shows: Liver function and any damage
✅ Some medications used during treatment can elevate liver enzyme levels.

5. Kidney Function Tests (Creatinine – Urea – eGFR)
Why it matters: Assesses kidney stress after dehydration or strong medications
✅ Important especially if symptoms included vomiting or fatigue.

6. Ferritin Test
What it shows: Iron levels and inflammation status
✅ Ferritin often rises due to strong immune response or ongoing inflammation.

7. Troponin Test or ECG (for those with heart symptoms)
Purpose: Detects any damage to the heart muscle
✅ Crucial if you had severe COVID-19, chest pain, or irregular heartbeat.

8. Lung Function Test (optional)
When to do it: If shortness of breath persists after recovery
✅ Assesses how well your lungs are functioning post-viral infection.

⚠️ When Should These Tests Be Done?

• Ideally 1 to 2 weeks after full recovery from COVID-19 or severe flu

• If symptoms like fatigue, shortness of breath, heart palpitations, or body aches persist after recovery

• Before returning to intense physical activity or heavy work

❓ Frequently Asked Questions
