From lab blood draws to saliva tests you can take at home, there are more ways to measure inflammation than ever before. This guide explains each option so you can choose the right one for your situation.
Chronic low-grade inflammation is linked to a wide range of conditions, including heart disease, type 2 diabetes, certain cancers, cognitive decline, and accelerated aging. The challenge is that it produces no obvious symptoms in the early stages. Most people have no idea their inflammatory burden is elevated until a clinical test reveals it.
Testing gives you information you cannot get any other way. A single CRP reading at an annual physical gives you one data point per year. Tracking CRP more frequently, across different diet patterns, sleep schedules, and stress loads, gives you a continuous picture of how your body is actually responding to your lifestyle choices.
The right testing method depends entirely on your goal. Clinical diagnosis requires clinical-grade testing. Ongoing wellness monitoring opens up faster, more accessible options that fit into everyday life.
Inflammation biomarkers are measurable substances in the body that rise or fall in response to the inflammatory process. C-reactive protein (CRP) is the most clinically validated and widely used. Others include erythrocyte sedimentation rate (ESR), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-a).
CRP responds quickly to changes in inflammation, typically within 6 to 12 hours, making it well suited for both acute and chronic monitoring applications.

| CRP Blood Test (Lab) | ESR (Sed Rate) Test | Cytokine Panels | At-Home Blood Spot CRP | Sensa At-Home Saliva Test | |
|---|---|---|---|---|---|
| Test Type | hsCRP from serum sample | Rate red blood cells settle in a tube | IL-6, TNF-a, and other signaling proteins | Dried blood spot CRP assay | Saliva-based CRP lateral flow assay |
| Sample | Venipuncture blood draw | Venipuncture blood draw | Venipuncture blood draw | Finger prick, dried blood spot card | Saliva, no needles or blood required |
| Where | Clinical lab or doctor's office | Clinical lab or doctor's office | Specialized research or clinical lab | At home, mail sample to lab | Fully at home, no mailing required |
| Turnaround | Hours to 1 to 2 days | Hours to 1 to 2 days | Days to 1 to 2 weeks | 3 to 7 days after mailing sample | Minutes, read in the Sensa app |
| Cost | Variable, often covered by insurance with a referral | Variable, typically covered with a referral | Expensive, often not covered by standard insurance | Moderate, subscription or per-test pricing | Affordable and predictable, no referral needed |
| Pain | Needle stick required | Needle stick required | Needle stick required | Minor finger prick | Painless saliva collection |
| Best For | Clinical diagnosis, physician-ordered monitoring, acute illness workups | Detecting active infection or autoimmune flares alongside other tests | Research protocols, complex immune profiling, specialized clinical cases | Infrequent at-home testing with lab-validated results | Regular wellness trend tracking, lifestyle feedback, daily or weekly monitoring |
Both approaches have a role in a complete inflammation picture. Understanding which context each serves helps you use them effectively.
Sensa uses a saliva-based lateral flow assay to detect CRP concentration. No needles, no clinic, no waiting room.
Use the collection tool included with your Sensa kit. No preparation needed. The whole process takes about 30 seconds.
Apply your sample to the Sensa test strip. The strip uses a lateral flow assay to detect CRP concentration in your saliva.
Scan the strip with the Sensa app to get your CRP reading in minutes. Your results are logged automatically so you can track trends over time.
Sensa gives you a simple, painless way to measure CRP at home and build a trend picture of your inflammation over time. Use it alongside your annual lab work for a more complete view of your wellness.
