Personally, if they said to see your doc immediately I would do just that. Just because your last lab report was fine doesn't mean a darn thing. Labs can change in a heartbeat, believe me.
So get in IMMEDIATELY and tell them that your instructor looked at your labs, and said to come in STAT. Make sure they look CLOSELY at your labs -- don't have them do it in the office -- perhaps you should have it done at the hospital. But DO IT. And do it SOON. God bless - and will you PLEASE let me (US) KNOW what the results are??? I REALLY want to know cause I care about you!! God bless and prayers are with you my new friend. Take care. Hugs, Lee
