At a glance
Long COVID blood testing measures markers of inflammation, organ function, coagulation, hormones, and immune activity in people whose symptoms persist after a COVID-19 infection. The lineup ranges from a 5-test mini screen (32 biomarkers) to a 19-test comprehensive evaluation (101 biomarkers), plus targeted cardiac-pulmonary, coagulation, cytokine, rheumatological, and EBV-reactivation panels. It is designed for adults with lingering fatigue, shortness of breath, brain fog, chest discomfort, or joint pain who want objective lab data to review with their doctor.
Best suited for
- Adults with symptoms that persist weeks or months after a COVID-19 infection, fatigue, shortness of breath, brain fog, joint pain, or heart palpitations
- Anyone who wants objective baseline data on inflammation, organ-function, and clotting markers after COVID-19
- People working with a physician or post-COVID clinic who want lab results to inform the conversation
- Those tracking recovery over time who plan to retest key markers and watch trends

Key biomarker ranges
Commonly used adult reference ranges for markers this panel measures, labs vary, so always interpret results against your lab's stated ranges and with your doctor.
Commonly used cutoffs: under 1 mg/L low, 1–3 mg/L average, over 3 mg/L high; acute illness or injury can spike results, so retesting confirms a trend.
| Zone | Range |
|---|---|
| Low | 0–1 mg/L |
| Average | 1–3 mg/L |
| High | 3–10 mg/L |
For eGFR, lower is worse: 90+ is consistent with full kidney function, while sustained values below 60 are the commonly used threshold of concern.
| Zone | Range |
|---|---|
| Kidney failure range | 0–15 mL/min/1.73m² |
| Reduced | 15–60 mL/min/1.73m² |
| Mildly reduced | 60–90 mL/min/1.73m² |
| Optimal | 90–120 mL/min/1.73m² |
The importance of testing
A COVID-19 infection can leave measurable changes across several body systems long after the acute illness resolves. These panels measure organ-function markers, including troponin, D-dimer, and renal markers, that reflect how the heart, lungs, and kidneys are working after infection, giving you and your doctor concrete numbers instead of guesswork.
Inflammatory and immune markers such as CRP, ESR, and cytokines help characterize lingering inflammation, one of the most closely watched features of post-COVID symptom patterns. Autoimmune screening flags immune responses associated with the infection, and a dedicated panel measures markers associated with Epstein-Barr virus (EBV) reactivation, which researchers have studied in connection with persistent post-COVID symptoms.
Coagulation testing tracks D-dimer and fibrinogen activity, markers associated with blood-clotting function that clinicians often monitor after COVID-19. Hormonal, metabolic, and nutritional markers round out the picture, since endocrine shifts and nutrient deficiencies are associated with symptoms like fatigue, weight fluctuation, and mood changes.
Because post-COVID recovery is typically gradual, a practical approach is to establish a baseline now, then retest periodically to track trends. Bring your results to your physician or a post-COVID clinic to decide which findings warrant follow-up.

What does a Long COVID blood test panel measure?
Long COVID panels measure markers of inflammation (CRP, ESR, cytokines), organ function (troponin, D-dimer, renal markers), coagulation (D-dimer, fibrinogen activity), hormones, nutrients, and autoimmune activity. Together these results describe how different body systems are functioning after a COVID-19 infection and give you specific values to review with your doctor.
Can these tests confirm Long COVID?
No, there is no single lab test that confirms Long COVID. These panels measure markers associated with inflammation, organ function, clotting, and immune activity so you and your physician can see which systems merit follow-up. Any out-of-range result should be reviewed with a healthcare provider.
Do I need a doctor's visit to order post-COVID lab testing?
No doctor's visit is required to order these panels, you can order online and have your sample collected at a local lab. Results are delivered to you directly, and you can then share them with your physician or a post-COVID clinic for interpretation.
Which Long COVID panel should I start with?
The 5-test Mini Panel ($99 with the current promotion) is a practical starting point for a first baseline, while the 10-test Expanded and 19-test Comprehensive panels cover more systems in one draw. If your symptoms are concentrated, for example chest discomfort, joint pain, or profound fatigue, the targeted cardiac-pulmonary, rheumatological, coagulation, cytokine, or EBV-reactivation panels focus on those marker groups.

Is direct-to-consumer lab testing available in every state?
No, direct-to-consumer lab testing is restricted or prohibited in New York, New Jersey, and Rhode Island, so residents of those states may be blocked at the partner's checkout. If you live elsewhere in the US, you can typically order online and visit a nearby patient service center for collection.
