My Friend Had Some Lab Work And Said The Blood

My friend had some lab work and said the blood in the syringe was yellow. She has very swollen feet and legs. She is bloated and looks as though she has gained 20 pounds. Her doctor gave her an antibiotic and advised that she go to a hospital which she refused to do. Her english is poor and she is having a lot of difficulty focusing. Any idea what could be causing these symtoms? I would like some advise before I see her tomorrow. Thank you.
