The Workwell Foundation provides exceptional expertise, particularly with their 2-day CPET testing. Jared and Staci were incredibly professional, thorough, and knowledgeable throughout the entire process. Their clear communication, attention to detail, and deep understanding of ME/CFS made a complex evaluation feel manageable and informative. Their work is both scientifically rigorous and deeply compassionate, an invaluable resource for anyone seeking clarity through objective testing.

It was a pleasure to come to the Workwell Foundation for my 2-day CPET (the physical exertion for the test and resulting PEM wasn't pleasurable, but you catch my drift). The entire process went smoothly, and I felt like I was well taken care of from beginning to end (from the initial referral, scheduling, doing the test, and follow-up). I'd highly recommend if you need some objective medical evidence to demonstrate your disability regarding Long Covid & ME/CFS.

I had an excellent experience with the Workwell Foundation. They got me scheduled quickly and provided clear instructions before my appointment. The office was comfortable and clean. Jared explained the steps of the CPET and EEG tests in detail, which put me at ease. I received the results report promptly, and I found the follow-up call with Staci to be thorough and educational. I recommend the Workwell Foundation for their professionalism and great service.

I highly recommend the Workwell Foundation for the 2 Day CPET test. Jared was professional and very informative from the beginning, with quick communication and clear instructions. He explained each step of the process along the way. I had to travel from out of state, and he was even kind enough to consider that and provide recommendations for air travel. The location was easy to get to with affordable accommodations nearby. Staci promptly scheduled a follow-up to explain the test results, which I much appreciated as they can be challenging for someone outside of the medical field to understand.

Frequently Asked Questions

Cardiopulmonary exercise testing (CPET) is considered the most accurate non-invasive tool for assessing maximal aerobic capacity and determining submaximal sustained exercise performance.

During the test, you pedal a stationary bicycle for about eight to twelve minutes. In some cases, the test may be shorter. As you exercise, we measure the air you breathe out to see how your body is using oxygen and producing carbon dioxide. We also monitor your heart rate, blood pressure, and oxygen levels using an electrocardiogram, a blood pressure cuff, and a pulse oximeter.

To learn more about CPET, you can browse our FAQ page.

Workwell Foundation developed the 2-day CPET protocol to assess post-exertional malaise and the ability to work on consecutive days. In many cases, a single test may not be sufficient to document an abnormal test.

The National Academy of Medicine states that 2-day CPET can objectively measure post-exertional malaise or a decline in functional capacity after physical exertion. If an individual is unable to work or recover from daily activities, a test-retest protocol can be used to document functional impairment and/or fatigue.

A signed physician referral is not always required. It is necessary for high-risk patients and those planning to submit a claim to health insurance.

If the patient is considered low- or moderate-risk and does not intend to submit an insurance claim, the physician referral is not required, and a superbill will not be issued.

Workwell Foundation specializes in conditions that involve exercise intolerance or PEM, including:

  • Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS)
  • Long COVID
  • Fibromyalgia Syndrome (FMS)
  • Other Fatigue-Related Illnesses

We provide educational materials that explain our services in clear, easy-to-understand language. 

The final report typically takes 2-3 weeks but can sometimes be expedited.

Workwell Foundation prepares a comprehensive report interpreting CPET results for those with complex fatiguing conditions. This report can be used for disability purposes due to its objective nature and ability to document fatigue and post-exertional malaise. Writing the report requires expertise and knowledge that combines health, exercise science, and the legal aspects of disability evaluation.

Most health insurance providers cover a portion of the testing fees. Medicare does not. Workwell Foundation is not a Medicare provider nor a member of any insurance group. Some patients have reported 100% coverage. The amount covered depends on the insurance company and plan.
