Hormone Level Interpretation Calculator

Work out hormone level interpretation instantly with clear inputs, formula shown and shareable results.

About Hormone Level Interpretation Calculator

Compares a hormone result with a commonly quoted adult reference range and reports where it sits relative to the limits and midpoint.

Formula

Reference comparison

Ranges used: total testosterone 300-1000 ng/dL, morning cortisol 5-25 mcg/dL, prolactin 4-23 ng/mL, TSH 0.4-4.0 mIU/L

Worked example

With the default values below, Hormone Level Interpretation Calculator returns Result status of Within the quoted reference range. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 2 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

Why do ranges differ between laboratories?

Assay platforms and local population sampling differ, so the report's own range always takes precedence.

Does timing matter?

Considerably. Testosterone and cortisol are highest in the morning, and prolactin rises with stress and sleep.
