I developed aloepecia areata in recent months, and my GP recommended a blood panel. The results came back mostly normal, except I have mildly low platlet count (139 x 10^9/L, as opposed to 150-400) and low blood serum iron (10.5mumol, as opposed to 14-31). Other iron specific indicators, like ferritin/transferrin, came back normal though. My other blood cell counts is normal as well.
I am to see my GP soon and I am most likely to be put on iron. I looked up in the net and there appear to be mixed opinion on aloepecia and iron deficiency. Is there any other differential diagnosis for my condition? Are there any tests I could ask my GP to conduct? Is there any auto immune problem I should ask my GP to check for? Or, is my problem to do with B12/folate deficiency? I am a lacto-vegetarian and I suspect I might not be getting enough B12. I don't go out in Sun much either, so D eficiency as well?
I am looking forward to here from experts.
