What This Test Measures

The test evaluates levels of specific proteins and markers that may indicate inflammation, lung stress, or organ dysfunction. These biomarkers are collected from a blood sample and analyzed to provide an overall risk assessment.

Why It’s Done

Your healthcare provider may order this test if you’re hospitalized with COVID-19 and at higher risk for severe symptoms, such as difficulty breathing or needing mechanical ventilation. It helps guide decisions about your care, including whether intubation (placing a breathing tube) may be necessary.

How the Test Works

Blood is drawn and processed to separate serum or plasma. Advanced laboratory techniques detect and quantify multiple biomarkers simultaneously, often using immunoassay or similar methods to measure their concentrations.

What to Expect Before the Test

No special preparation is needed. You may have a small needle inserted into a vein in your arm, and you’ll rest while the blood is drawn. The process usually takes a few minutes.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Will this test show if I already have COVID-19?
No, this test does not diagnose COVID-19. It assesses your risk of needing a breathing tube during the illness, based on biomarkers that may appear in response to severe infection.
What if my results are abnormal?
Abnormal results may indicate a higher risk of needing medical interventions like intubation. Your doctor will discuss these findings with you and adjust your care plan accordingly, possibly including closer monitoring or additional treatments.
How often will I need this test?
The frequency depends on your medical condition and response to treatment. Your healthcare team will determine if repeated testing is needed during your hospitalization or recovery.
