The following is a list of possible tests to diagnose or help manage the symptoms of myalgic encephalomyelitis, fibromyalgia, Ehlers-Danlos syndrome, postural orthostatic tachycardia and mast cell activation syndrome. Many of these tests have not been established as the standard of care and are thus in the research phase.

Test Type Lab(s) ME/CFS EDS POTS MCAS
Red blood cell magnesium Blood (intracellular) US: Quest A randomized, double-blind, placebo-controlled trial found that patients with CFS had lower rbc magnesium than controls. Treatment with magnesium sulphate via intramuscular injection improved symptoms.[1]
Carnitine Serum
Acetylcholine autoantibodies
Pyruvate dehydrogenase
Natural killer cell function
VO2 Max Test
2-day cardiopulmonary exercise test

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.

postural orthostatic tachycardia syndrome (POTS) - A form of orthostatic intolerance where the cardinal symptom is excessive tachycardia due to changing position (e.g. from lying down to sitting up).

serum - The clear yellowish fluid that remains from blood plasma after clotting factors have been removed by clot formation. (Blood plasma is simply blood that has had its blood cells removed.)

VO2max - the maximum amount of oxygen the body can utilize during a specified period of usually intense exercise

two-day cardiopulmonary exercise test (CPET) - A diagnostic test which involves testing an ME/CFS patient exercising on an exercise machine, while monitoring their respiration, especially oxygen consumption. This test is repeated the following day in order to confirm the patient's inability to replicate the first-day performance. This test is thought to be the most objective way to detect post-exertional malaise.
