Sodium Level

Sodium is the key electrolyte that regulates body water and the osmotic balance across cell membranes. An abnormal reading is usually driven by a change in water balance — dehydration or fluid overload — rather than sodium itself.

138mEq/L

What it means

Within the normal range (135–145).

Formula

Result = band(Sodium (mEq/L))

This is a reading aid, not a diagnosis. A sudden shift can be a medical emergency and needs clinical follow-up.

Frequently asked questions

QHow is Sodium Level calculated?

Result = band(Sodium (mEq/L)) — Sodium is the key electrolyte that regulates body water and the osmotic balance across cell membranes. An abnormal reading is usually driven by a change in water balance — dehydration or fluid overload — rather than sodium itself.

QCan you walk through an example?

With Sodium (mEq/L) 138mEq/L, the answer is Result 1.

QWhat do I need to enter?

Enter Sodium (mEq/L). 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 Sodium (mEq/L) (mEq/L) moves the answer to Sodium (mEq/L) (mEq/L) 100 → Result 0 and Sodium (mEq/L) (mEq/L) 180 → Result 2. 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?

This is a reading aid, not a diagnosis. A sudden shift can be a medical emergency and needs clinical follow-up.
