Tests that measure C-Reactive Protein

Post COVID-19 Panel

Laboratory
Quest Diagnostics
Test code
11454
Specimen
See individual tests
Fasting
Not stated as required

What the laboratory says this test is for

About 10-30% of patients continue with lingering symptoms four or more weeks after COVID-19 infection, including those who had mild, or no symptoms termed as post-COVID conditions. The Centers for Disease Control (CDC) provided Interim Guidance for Assessment and Testing for Evaluating and Caring for Patients with Post-COVID Conditions. The CDC recommends laboratory testing be guided by the patient history, physical examination, and clinical findings. A basic panel of laboratory tests might be considered for patients with ongoing symptoms to assess for conditions that may respond to treatment, until more information and evidence is available for specific laboratory testing for post-COVID conditions. This panel is to be considered for persistent symptoms if basic testing such as Complete Blood Counts, Basic Metabolic Profile, and Liver Function Tests has been completed.

This panel is to be considered for basic testing if no previous testing was performed.
