hello Dr. Grief - I just had norovirus last weekend which lasted about 48 hours(horrible thing). I was due for a blood test which I get every 4 months to monitor liver function because of my medications for RA. I went the morning following the virus for no particular reason except it was a convenient day to do a fasting test along with the other requested tests. My liver readings were elevated and I was wondering if vomiting, diarrhea, and not eating or drinking normally could skew the test results? If you do not have enough information I can call my doctor s office tomorrow to ask, but thought I d check here now.
Yes a norovirus infection can cause raised liver enzymes. What I would do is repeat the liver enzymes two to four weeks after the infection has settled to see the trend of the liver enzymes. If the liver enzymes are settling then I would not worry and would attribute it to the viral infection and this is not something to worry about.
