For 2 weeks in February, I had the flu & took flu meds, every 4 hrs. for 2 weeks. I was still a little sick when I had a blood test & my ALP was elevated from 153 to 574. My ALp has never been over 200 in the last 8 years. Does anyone know if the flu & meds could have elevated it this much? I asked my gastro Dr. & he answered...."who knows??" So maybe someone else's doctor has said.
