The events "liver enzymes are 5 times the normal limit", "feeling a little more tired than usual" and "his resting heart rate went up from 60 to 70 after he got the booster vaccine" were evaluated at the physician office visit.

Additional Information: He was calling about Pfizer covid booster. For the last several years he has been donating plasma once or twice a week. Last Wednesday he made a plasma donation and the following day on Thursday he got the Pfizer covid booster. This Monday, he made another plasma donation and he also got his blood work done for his annual physical. When he went back Wednesday 05Jan2022 to donate plasma, he was informed that his liver enzymes are way higher then they need to be. Yesterday he went in for physical and to talk about his labs. His doctor told him he needs to stop drinking alcohol and that his liver enzymes are 5 times the normal limit. He does not drink alcohol. The reason he is tying this perhaps to the Pfizer booster, is since his liver enzymes were tested twice a week for several years, he was never informed of any abnormality. Last Wednesday 29Dec2021 his liver enzymes were normal, and this Monday his liver enzymes are more than 5 times the upper limit after getting the booster. At the time when he met with doctor yesterday he felt fine, he still feels fine. He did not make a connection with the vaccine till his visit with the doctor had ended. His doctor thought/assumed he was eating a horrible diet based on his labs. He was informed of elevated Liver enzymes on Wednesday 05Jan2022, after his blood work was drawn on Monday for plasma and annual physical. Treatment, he declines any, he was told to come back in 6 weeks to get another blood test. Outcome was not had labs again yet. He donated plasma again on Wednesday and he should find out about his labs that were drawn on Wednesday, next Monday. Every time he goes in to donate plasma on Mondays and Wednesdays, he gets his blood drawn. He has not taken aspirin for about a year. He has no known medical issues. He takes an allergy pill and a nasal spray. Other than feeling a little more tired than usual, he did not attribute it till he went in the doctor. Reports maybe he has a little mental fogginess and a little more tired. Today is better than yesterday. He has a Fitbit and a way he can tell if he gets sick is that his resting heart rate goes up. In Nov2021 when he got the flu his resting heart rate went up to 80 over the course of two weeks, it gradually increased, then it came back down over the next couple of weeks. His resting heart rate went up from 60 to 70 after he got the booster vaccine. Yesterday morning he thought he was fighting something, states it may be just be a normal reaction to vaccine since a vaccine triggers an immune response.  No follow-up attempts are possible. No further information is expected.
