5 succinct key points
- Derangement in liver enzymes is common in patients with infectious
mononucleosis.
- The reported median time to resolution of deranged liver function
tests is 8 weeks but can persist beyond six months in a minority of
patients.
- Deranged LFTs caused by infectious mononucleosis is self-limiting in
majority of patients.
- Evidence suggests serial blood tests until resolution is not required
in immunocompetent patients with subclinical derangement in LFTs.
- Routine abdominal ultrasound is not required in IM to investigate
deranged liver function test in immunocompetent patients with
subclinical derangement in LFTs.
