Testosterone Level

Testosterone is the male sex hormone involved in muscle mass, energy and sexual function. It peaks in the morning, which is why testing is usually done then, and it declines gradually with age.

What it means

Within the normal range (300–1000, adult male reference).

Formula

Result = band(Testosterone (ng/dL))

These bands do not apply to women or children. This is a reading aid, not a diagnosis — a low result should be confirmed with a repeat test.

Frequently asked questions

QHow is Testosterone Level calculated?

Result = band(Testosterone (ng/dL)) — Testosterone is the male sex hormone involved in muscle mass, energy and sexual function. It peaks in the morning, which is why testing is usually done then, and it declines gradually with age.

QCan you walk through an example?

With Testosterone (ng/dL) 350ng/dL, the answer is Result 1.

QWhat do I need to enter?

Enter Testosterone (ng/dL). The result recalculates as you type, and an empty box counts as zero.

QHow much does the answer move if I change a number?

Changing only Testosterone (ng/dL) (ng/dL) moves the answer to Testosterone (ng/dL) (ng/dL) 175 → Result 0 and Testosterone (ng/dL) (ng/dL) 700 → Result 1. The table below lays out five steps.

QHow are the numbers rounded?

Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.

QAnything to watch out for?

These bands do not apply to women or children. This is a reading aid, not a diagnosis — a low result should be confirmed with a repeat test.
