MASLD triage is practical when anchored to fibrosis risk rather than transaminases alone. FIB-4 from routine bloods separates low-risk patients from those needing ELF testing, elastography, or hepatology referral, while 5%, 7–10%, and 10–15% weight-loss targets map to steatosis, inflammation, and fibrosis.

Peanut allergy is diagnosed by history first, not by a positive test alone. Rapid onset after exposure, multisystem features and high-risk eczema matter most, while early regular peanut introduction and prompt epinephrine remain the practical prevention and treatment anchors.
