Hi again ( I just posted as a new member)

So I have a question about the blood Prostaglandin D2 test. Anyone else have this (it was ordered by accident for me)... anyway, it came back positive 185 (ref range up to about 135?   (can't remember).  

Anyone know if menstrual cycle influences this? As I keep reading the uterus is a place P D2 is produced? I ask because I had that blood drawn the day before my cycle began.  (wishful thinking on my end to have a way to explain this test result).   I hear about false negatives all the time in relation to MCAD... but false positives?    

The test result came with a disclaimer that it wasn't approved by FDA and shouldn't be used solely as diagnostic and it intended for research purposes.

Thanks for any insight!!!
