What This Test Measures

The test analyzes multiple blood components, including inflammatory markers, oxygen-related substances, and organ function indicators, to create a risk score. These biomarkers may reflect how your body’s response to COVID-19 could impact your breathing and overall health.

Why It’s Done

Your healthcare provider may order this test if you’re hospitalized with COVID-19 and at high risk for severe symptoms. It helps guide decisions about your care, such as whether you might need additional support like a ventilator.

What to Expect Before the Test

No special preparation is needed. A blood sample will be drawn from a vein, typically in your arm. The process is quick and usually painless.

What to Expect After the Test

After the blood draw, you may feel slight discomfort or bruising at the site, which should resolve within a few days. You can resume normal activities unless your provider advises otherwise.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Higher risk scores may indicate a greater likelihood of needing mechanical ventilation, which can help healthcare teams tailor treatments to your needs. While not a definitive prediction, it provides critical information to monitor your condition closely and adjust care plans as needed.
