What is this test?

This item documents that a healthcare professional reviewed your health conditions and discussed your increased risk of severe COVID-19. It is a status or notification record rather than a laboratory test.

Why might I need this test?

This record may be used to help guide preventive care, treatment decisions, and recommendations for avoiding or promptly managing COVID-19. It may also be included in your medical history for continuity of care.

How is the test performed?

A clinician reviews your medical history and underlying conditions, then documents whether you were informed about your risk of severe COVID-19. No blood sample, swab, or other specimen is required.

How do I prepare for the test?

No special preparation is needed. It may help to have an updated list of your health conditions, medications, allergies, and recent COVID-19 vaccinations available for the review.

Reference range

Adult males: 7-56 U/L; Adult females: 7-43 U/LN/A

Specimen: serum

No special preparation required. Avoid fatty meals before the test if possible.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

This record confirms that elevated COVID-19 risk due to an underlying condition was identified and communicated. It may prompt closer monitoring, earlier treatment if infected, or other preventive measures. It does not mean that you currently have COVID-19.

Short name

COVID-19 severe-risk notification

Frequently asked questions

Does this result mean I have COVID-19?
No. This is a risk-status or communication record and does not diagnose a current or past infection.
What should I do if I am at severe risk?
Ask your clinician about vaccination, antiviral medicines, exposure precautions, and when to seek testing or care. Recommendations depend on your individual health conditions and risk factors.
Can this record change over time?
Yes. Your risk may change as your health conditions, treatments, vaccination status, or other factors change, so regular review is important.
