Thymoma-associated myasthenia gravis is a severe form of autoimmune muscle weakness that occurs when a thymoma (tumor of the thymus gland) triggers the production of antibodies that attack muscle receptors. It is caused by abnormal immune system activation from the thymus tumor, leading to high levels of striated muscle antibodies and acetylcholine receptor antibodies. The Myasthenia Gravis Panel 3 is the most important test for diagnosis because it detects striated muscle antibodies that specifically indicate thymoma presence.

Thymoma-associated myasthenia gravis is caused by a thymoma, which is a tumor of the thymus gland that triggers abnormal immune system activity. The thymus tumor causes the body to produce antibodies that attack acetylcholine receptors at the neuromuscular junction, preventing proper muscle contraction. Additionally, the thymoma stimulates the production of striated muscle antibodies that directly indicate tumor presence and correlate with more severe muscle weakness and fatigue.
The Myasthenia Gravis Panel 3 is the most important test for thymoma-associated myasthenia gravis because it detects striated muscle antibodies, which are specific markers that indicate the presence of a thymoma in patients with myasthenia gravis. High levels of these antibodies are particularly associated with more severe forms of the disease and help confirm the thymoma-associated variant. This comprehensive panel is essential for distinguishing thymoma-associated myasthenia gravis from other forms of the condition, allowing healthcare providers to determine appropriate treatment strategies including potential surgical removal of the thymoma.
You should get tested if you experience progressive muscle weakness that worsens with activity and improves with rest, especially drooping eyelids, double vision, difficulty swallowing, or trouble breathing. Testing is particularly important if you have already been diagnosed with myasthenia gravis and your symptoms are severe or rapidly worsening, as this may indicate thymoma presence. You should also get tested if imaging studies suggest a mass in your chest or thymus area, or if you have unexplained muscle fatigue that affects your daily activities and quality of life.

What this means
Your testosterone levels are slightly below the optimal range. While this is not necessarily cause for concern, it may contribute to occasional fatigue, reduced motivation, or lower muscle mass over time.
Recommended actions
Increase resistance or strength training
Prioritize 7–8 hours of quality sleep per night, try to reduce stress
Include more zinc- and magnesium-rich foods (like shellfish, beef, pumpkin seeds, spinach)
Consider retesting in 3–6 months
Not overhyped or overpriced. Just comprehensive blood testing made simple and for everyone.
