I have had increasing hair loss over the past four or so months so decided it's time to see a doctor. I have the appointment in the morning. What blood test should I request? I've read about getting ferritin levels checked which I will ask for but I also want to get my vitamin levels checked. Do these blood tests have a special name or do I just list off all the things I want checked which I think may be related to my hair loss? Such as vitamin B? Are there any particular blood tests I should ask for? I have recently been diagnosed with a thyroid condition. Thanks.
