A POTS test is not a single blood draw you can do at home. POTS is diagnosed clinically, by measuring your heart rate and blood pressure as you move from lying down to standing, either with a supervised active stand test or a tilt-table test. An inflammation blood panel does not diagnose POTS. It can add context about immune signaling that standard labs leave out, to review with your own doctor.
Key takeaways
- A POTS test is a heart-rate and blood-pressure measurement on standing, not a blood biomarker. The standard is a sustained heart-rate rise of at least 30 beats per minute (40 for teens) within ten minutes of standing, without a large blood-pressure drop.
- The two clinical tools are the active stand test and the tilt-table test. Both are done with a clinician.
- There is no blood test that diagnoses POTS, and no at-home kit that replaces the stand or tilt-table measurement.
- Some people with POTS also carry signs of immune activation. An inflammation panel measures cytokines and chemokines as context, not as an autonomic diagnosis.
- This is measurement and benchmarking for research and informational use, to discuss with your clinician. It is not a substitute for medical care.
What is a POTS test, and can you do it at home?
POTS stands for postural orthostatic tachycardia syndrome. The defining feature is an excessive, sustained rise in heart rate when you stand up, in the absence of a large drop in blood pressure. A POTS test measures exactly that: your heart rate and blood pressure lying down, then across the first ten minutes of standing. The diagnostic threshold most clinicians use is a heart-rate increase of at least 30 beats per minute in adults, or at least 40 in adolescents, with orthostatic symptoms lasting several months and no other clear cause.
You can record your own heart rate at home with a monitor, and many people do this to bring a symptom log to their appointment. That home data can be useful, but it is not a formal diagnosis. A proper active stand test needs accurate, repeated blood-pressure readings and clinical interpretation, and a tilt-table test needs specialized equipment. So the honest answer to "can I do a POTS test at home" is: you can gather helpful data, but the diagnosis itself is clinical.
What is the difference between an active stand test and a tilt-table test?
The active stand test is the simpler of the two. You lie down for a set period, then stand actively while a clinician records heart rate and blood pressure at intervals. It is quick and needs little equipment, which is why it is often the first step.
The tilt-table test straps you to a table that tilts you upright passively, so your leg muscles do not pump blood back to your heart the way they do when you stand on your own. This can reveal patterns that an active stand misses. It is usually reserved for less clear cases or when fainting is involved. If you want the detail on what that procedure records and how to prepare, see our guide to the tilt-table test and what it measures. The patient organization Dysautonomia International is a reliable, plain-language starting point on both tests (Dysautonomia International).
Is there a blood test for POTS?
No single blood test diagnoses POTS. Bloodwork is often ordered around a POTS workup to rule out other explanations for a fast heart rate, such as anemia, thyroid problems, or dehydration, using routine labs like a CBC, ferritin, or thyroid panel. Those tests do not confirm POTS; they help exclude look-alikes. The diagnosis still rests on the heart-rate response to standing.
What research has noticed is that POTS does not always occur in isolation. A meaningful share of cases follow a viral illness, and some people with POTS also show signs of immune activation. This is an area of active study rather than settled diagnostic fact. It is why inflammation profiling is discussed as context alongside a POTS workup, never as a replacement for the stand or tilt-table measurement.
What can an inflammation panel add to a POTS workup?
An inflammation panel does not tell you whether you have POTS. What it can do is measure the immune signaling that routine labs skip. Instead of a lone CRP value, a broad proteomic panel reads many cytokines and chemokines at once, markers such as IL-6, TNF, IFN-gamma, and the interferon-inducible chemokine CXCL10, and benchmarks each against a healthy reference range. Because you can retest over time, you can see which signals shift and which stay steady.
For someone whose standard bloodwork keeps coming back normal, this is a way to gather objective data on the inflammatory-tone side of the picture, to bring to the doctor who is managing the autonomic side. If that fits your situation, you can see what Muno Mirror measures. It is a measurement and benchmarking tool for research and informational use, not a diagnosis of POTS or any other condition, and not a substitute for clinical care.

Frequently asked questions
Can a blood test diagnose POTS?
No. POTS is diagnosed by measuring your heart-rate response to standing, using an active stand test or a tilt-table test. Blood tests are sometimes used to rule out other causes of a fast heart rate, but no blood biomarker confirms POTS.
How do I test for POTS at home?
You can record your heart rate lying down and then standing, using a home monitor, and log your symptoms over several days. This can be useful information for your appointment, but it is not a formal diagnosis. A clinician needs to measure blood pressure alongside heart rate and interpret the pattern.
What heart-rate increase indicates POTS?
The commonly used threshold is a sustained rise of at least 30 beats per minute within ten minutes of standing in adults, or at least 40 beats per minute in adolescents, without a large blood-pressure drop, alongside orthostatic symptoms lasting several months and no other clear cause.
Why would someone with POTS get an inflammation test?
Some people with POTS, especially after a viral illness, also show signs of immune activation. An inflammation panel measures cytokines and chemokines as context, not as an autonomic diagnosis. It can add objective data to discuss with the doctor managing your POTS, particularly when routine labs read normal.
