HOMA-IR
Insulin resistance, worked out from your fasting insulin and fasting sugar.
A useful early warning, but it is calculated — no extra sample was taken for it.
This one isn’t a test
HOMA-IR = (Fasting Insulin × Fasting Glucose) ÷ 405
No extra sample was taken for this and no extra assay was run. It is arithmetic on numbers already on your report — but it still adds a line to the advertised test count.
Computed from Fasting Blood Sugar and Fasting Insulin.
That does not make the number useless — eGFR is calculated and doctors act on it every day. It means it should not be counted as a separate test when you are comparing what a package costs.
Calculated from this result
Once a lab has this measurement, these lines cost it nothing to add.
