I recently got this done at the request of the functional medicine guy I am working with. I also ejaculated twice 12 hours before doing the test so I primed my body to be in a POIS state. We got the RA panel done in the attempt to rule out autoimmunity. All my markers seem normal and healthy.
ANA: < 160 (ref range: < 160)
RF: < 14 (ref range: < 14)
CCP: < 5 (ref range: < 5)
ESR: 2 mm/h (ref range: < 11)
Uric acid: 0.32 mmol/L (ref range: 0.18-0.47)
CRP: < 0.7 mg/L (ref range: 3.0)
25-hydroxy Vitamin D: 104 nmol/L (ref range: < 50 nmol/L deficiency, < 20 nmol/L severe deficiency)
I am currently waiting on the result of 1,25 Vitamin D (according to my functional medicine guy, a different type of vitamin D that can be useful to potentially diagnose autoimmunity when you take into account the ratio between the two types).
Keep in mind my POIS symptoms are considerably low nowadays. I continue to get body aches (most significant in first hour or two), relatively low energy for a day or two, and slight mood changes (most significant in first hour or two, clears up after a good sleep). My symptoms also seem to be correlated with plant foods I eat so I currently abide by a strict diet to keep this at bay. It would have been interesting to get these tests done when my symptoms were at their peak years ago (chronic fatigue, chronic anxiety, chronic brainfog).
The only marker I've been able to see a direct correlation with my POIS is neutrophils. They drop immediately after experiencing POIS (and must take a bit of time to return to normal). I've tested this now multiple times with different blood tests.
