TSAT and Iron Panel Algorithm for Hemochromatosis Screening
AASLD uses TSAT ≥45% as the sensitive phenotypic trigger (detects ~98–100% of C282Y homozygotes). Pair with ferritin, then HFE genotyping—do not use TSAT alone as phlebotomy endpoint.

HFE C282Y Genetics and Incomplete Penetrance Deep Dive
C282Y/C282Y is common in Northern European ancestry (~1/220–250) but severe end-organ disease is uncommon. Genotype is risk; TSAT/ferritin and organs are expression.

Ferritin Interpretation with Inflammation: Iron Overload Context
Ferritin rises as an acute-phase reactant. Pair with TSAT, sex-specific cutoffs, and the 1000 µg/L fibrosis node in HFE disease—never read ferritin alone during illness.

Iron Overload Diet Modifiers and Hard Avoidances
Diet is adjunct, not cure. Phlebotomy removes ~250 mg iron per unit weekly versus ~2–4 mg/day absorption swing. Hard stops: iron pills, vitamin C pills, raw shellfish, and alcohol with liver disease.

Reading an Iron Panel: Step by Step (2026)
Read ferritin with TSAT, separate inflammation from overload, know when HFE genetics help, and avoid ferritin-only panic.

Secondary Iron Overload: Transfusions, Anemias, and Parenteral Iron
Acquired iron excess from transfusions, ineffective erythropoiesis, or IV iron—not classic HFE hepcidin failure. Phlebotomy often fails when anemia is present.

Non-HFE and Juvenile Hemochromatosis: HJV, HAMP, TFR2, Ferroportin
About 10–15% of inherited iron overload is non-HFE. Juvenile forms (HJV/HAMP) load fast with early heart and endocrine disease—negative HFE is not “not genetic.”

Iron Overload Diet Modifiers: Alcohol, Vitamin C, Shellfish, Supplements
Diet is a modifier, not a cure. Phlebotomy removes ~250 mg iron per unit weekly; diet shifts absorption only a few milligrams per day.

MRI Liver Iron, Cardiac T2*, and When Biopsy Still Matters
MRI quantifies liver iron concentration and cardiac T2* noninvasively. In HFE HH, biopsy is mainly for fibrosis staging when ferritin exceeds 1000 µg/L or enzymes rise—not routine genetic diagnosis.

HFE Genetic Testing Workflow: Who to Test and How to Interpret
HFE genotyping follows elevated iron studies or first-degree relatives of known HH—not unselected population screening. Homozygotes, compound hets, and simple hets map to different next steps.

Hemochromatosis in Women: Menstrual Protection and Menopause Unmasking
Women inherit HFE risk equally but show lower clinical penetrance—until menses stop. Re-check iron status around menopause; never say women cannot get hemochromatosis.

Hemochromatosis in Men: Earlier Presentation and Higher Complication Rates
Men inherit HFE risk equally but present earlier and develop complications more often—about 28% vs 1% documented disease in one classic C282Y cohort comparison.

Hemochromatosis Screening: Family Cascade vs Population Genetics
Screen first-degree relatives with iron studies plus HFE testing. Societies recommend against universal population genotype screening because penetrance is incomplete.
