Inflammatory markers in the blood

C-reactive protein (CRP) (marker for inflammation in the body), ferritin (acute phase reactant), and D-dimer (helps in ruling out a harmful blood clot and tells if you need a blood thinner or not) are blood tests which can tell about inflammatory markers in the blood.

"You might not have a lot of symptoms, but if your inflammatory markers are high, you need to have an aggressive approach. The doctors may recommend a CT scan to check if there is mild pneumonia. All of this helps in controlling the infection on time," says Dr Tickoo.

Symptoms to watch out for

Patients who have tested positive for COVID-19 will have symptoms like dry cough, breathlessness, fever, loss of sense of taste and smell, tiredness and chest pain amongst others.

In case the infection has spread to the lungs, it may show symptoms like persistent cough and fever, chest discomfort, breathless on exertion, low oxygen saturation and blood inflammatory markers mentioned above. "It usually happens after five days of the infection," Dr Tickoo adds.

Important to be in constant touch with the doctor

A person who has tested positive for COVID-19 is most likely to already be in constant touch with the doctor. "Once you have involvement in the lungs, the doctor will take a call if you need a CT scan, or if need to be prescribed some steroids, or if you need admission in the hospital for appropriate treatment," he explains.

If the condition progresses to be more severe with complications, patients may land up in Intensive Care Unit (ICU) or have respiratory failure. However, in majority of the cases, people who don't have severe symptoms and have mild pneumonia can get better with medicines and steroids, Dr Tickoo shares.
