T3 REVERSE -- "The mix of treatments needed varies from patient to patient. There are some abnormalities that are common. For instance, close to 100% of individuals with these syndromes have low thyroid. This is, however, usually not picked up on the standard blood tests because the TSH is not elevated in these individuals due to pituitary dysfunction. Many of these individuals will also have high levels of the anti-thyroid reverse T3, which is usually not measured on standard blood tests. In addition, the majority of individuals can also have a thyroid receptor resistance that is not detected on the blood tests. Consequently, thyroid treatment, especially with timed release T3, is effective for many patients. T4 preparations (inactive thyroid) such as Synthroid and Levoxyl do not work well for these conditions."

Sed Rate (ESR) --- The most consistent laboratory abnormality in patients with CFS is an extremely low erythrocyte sedimentation rate (ESR), which approaches zero. Typically, patients with CFS have an ESR of 0-3 mm/h. An normal ESR or one that is in the upper reference range suggests another diagnosis.
CD4 Count --- "We have 155 cases with random CD4 counts below 500, 62 cases below 400, 21 below 300 and 3 below 200." --- Dr. Paul Cheney
Cheney also says, "some of my sickest patients have elevated CD4 counts" Source: http://www.immunesupport.com/92fal007.htm

Holter Test (heart) "All 60 patients with CFS showed repetitively flat to inverted T waves alternating with normal T waves"
Cardiac involvement in CFS patients (highly recommended):
Most patients with CFS usually have 2 or 3 of the following abnormalities:
Decreased NK cells, either the percentage or their activity
Pathogen Testing --- EBV titer, CMV titer, HHV-6 titer (preferred methology & lab):
