How to Test for Inflammation: A Complete Guide to Your Options
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.
The most practical way to test for inflammation is measuring C-reactive protein (CRP), the most clinically validated inflammatory marker, produced by the liver in response to inflammation. Other markers include ESR, IL-6, and TNF-alpha. Options range from a traditional lab blood draw, which gives a single precise reading for clinical use, to at-home CRP tests like Sensa that use saliva instead of a needle and let you track trends across weeks and months. The right choice depends on whether you need a clinical diagnosis or ongoing wellness monitoring.
Why Testing for Inflammation Matters
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.
What Are Inflammation Biomarkers?
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.

Five testing methods evaluated across seven dimensions that matter most when choosing how to monitor your inflammation.
| 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 |
When to Choose Lab Testing vs. At-Home Monitoring
Both approaches have a role in a complete inflammation picture. Understanding which context each serves helps you use them effectively.
Choose lab testing when...
- A healthcare provider has ordered an inflammation test as part of diagnosing or managing a condition
- You are experiencing symptoms such as unexplained joint pain, fatigue, or fever that may indicate an acute inflammatory event
- You need results interpreted alongside other bloodwork such as a complete metabolic panel or lipid profile
- A very high CRP reading from at-home testing prompts you to seek clinical follow-up
- You need clinically validated precision to guide a treatment decision
- Your doctor suspects an autoimmune condition and wants a comprehensive inflammatory picture including ESR and cytokines
Choose at-home monitoring when...
- You want to understand how diet, sleep, exercise, or stress is affecting your inflammation over time
- You want to test more than once per year without scheduling clinic visits
- You are trialing a lifestyle change, such as a new eating pattern or recovery protocol, and want objective feedback
- You prefer a painless experience with no needles or blood draws
- You want to build a trend log of CRP readings to share with your doctor at your next visit
- You are managing a chronic condition and want to monitor your inflammatory baseline between appointments
What Your CRP Number Means
High-sensitivity CRP (hsCRP) is measured in milligrams per liter (mg/L). These widely referenced cardiovascular risk ranges are educational and not a substitute for a healthcare provider's interpretation.
| hsCRP level (mg/L) | Category | What it typically reflects |
|---|---|---|
| Below 1.0 | Low risk (optimal) | Low inflammatory activity |
| 1.0 to 3.0 | Average risk | Common range; may reflect diet, stress, or sleep |
| Above 3.0 | High risk | Meaningful inflammatory activity |
| Above 10.0 | Acute | Often an active infection or injury; consult a provider |

How Sensa Measures Inflammation at Home
Sensa uses a saliva-based lateral flow assay to detect CRP concentration. No needles, no clinic, no waiting room.
Collect a Saliva Sample
Use the collection tool included with your Sensa kit. No preparation needed. The whole process takes about 30 seconds.
Insert the Test Strip
Apply your sample to the Sensa test strip. The strip uses a lateral flow assay to detect CRP concentration in your saliva.
Read Your Result in the App
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.
Frequently Asked Questions
What is the best way to test for inflammation?
Measuring C-reactive protein (CRP) is the most practical way to test for inflammation, because CRP is the most clinically validated and widely used inflammatory marker. You can measure it through a traditional lab blood draw for a single precise reading, or through an at-home CRP test for ongoing tracking. Other markers include ESR, IL-6, and TNF-alpha.
What blood tests measure inflammation?
The main markers measured are C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-alpha). CRP is the most clinically validated and widely used because it responds quickly to changes in inflammation, typically within 6 to 12 hours, making it suitable for both acute and chronic monitoring.
Can you test for inflammation at home?
Yes. At-home CRP tests like Sensa measure C-reactive protein from saliva with no blood draw and no clinic visit, letting you track your inflammatory trends across weeks and months. At-home testing is a general wellness tool for monitoring, not a diagnostic replacement for clinical testing.
How often should you test your inflammation?
A single CRP reading at an annual physical gives you just one data point per year. Testing more frequently, across different diet patterns, sleep schedules, and stress loads, gives a continuous picture of how your body responds to your lifestyle, which is where at-home monitoring is most useful.
