Tests
This test looks for smooth muscle antibodies (SMAs) in a sample of your blood. High levels of SMAs are usually a sign of a chronic (long-lasting) liver condition called autoimmune hepatitis .
Indicators
An element with atomic symbol Na, atomic number 11, and atomic weight 23.
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.

If you have an infection or chronic illness affecting the lungs or airways, sputum can settle in your lungs, and you may also cough it up
Glossary Term
A measure of the range of values in a set of numbers. Standard deviation is a statistic used as a measure of the dispersion or variation in a distribution, equal to the square root of the arithmetic mean of the squares of the deviations from the arithmetic mean.
Glossary Term
The standard deviations of the sample in a frequency distribution, obtained by dividing the standard deviation by the square root of the total number of cases in the frequency distribution.
Glossary Term
An established procedure to be followed in carrying out a given operation or in a given situation.
Glossary Term
The substitution of some value for a missing data point or a missing component of a data point.
Tests
A stool elastase test measures the amount of elastase in your stool (poop). Elastase is a type of digestive enzyme, a protein that speeds up certain chemical reactions in your body. The pancreas, a gland that sits behind your stomach, makes these digestive enzymes to help your body break down food and absorb nutrients. Your body can then use these nutrients for energy, growth, and repairing cells.
