Tests
A sodium blood test measures the amount of sodium in your blood. Sodium is a type of electrolyte . Electrolytes are minerals that have an electrical charge when they are dissolved in water or body fluids. You have electrolytes in your blood, urine (pee), tissues, and other body fluids. They help control the amount of fluid and the balance of acids and bases (pH balance) in your body. Sodium also helps your nerves and muscles work properly.
Tests
An aldosterone test measures the amount of aldosterone (ALD) in your blood or urine (pee). ALD is a hormone made by your adrenal glands, two small glands that sit above your kidneys. ALD helps keep your blood pressure stable by helping to balance the levels of two electrolytes in your blood, sodium and potassium .
Tests
The determination of the amount of unmeasured anions (computed as sodium minus the chloride and bicarbonate) present in a sample.

Tests
Osmolality tests measure the amount of certain substances in your blood, urine, or stool (poop). The tests can show how your kidneys are working and whether you have an unhealthy fluid balance .
Tests
The determination of the amount of para-aminohippurate sodium present in a sample.
Tests
This test measures the level of renin in your blood. Renin is an enzyme, a protein that speeds up certain chemical reactions in your body. It's made by your kidneys. When your blood pressure or sodium decreases or your potassium increases, your kidneys release renin. That's because renin also acts as a hormone (a chemical messenger in your bloodstream that controls the actions of certain cells or organs) to help control your blood pressure.
Tests
A quantitative measurement of the amount of sodium present in a sample of serum.
Tests
The determination of the amount of the sodium clearance in a sample.
Tests
A quantitative measurement of the amount of sodium present in a sample.
Tests
The determination of the ratio of sodium compared to creatinine present in a sample. The measurement may be expressed as a ratio or percentage.
