The Test Sample

What is being tested?

Albumin is the most abundant protein in the blood plasma. It keeps fluid from leaking out of blood vessels; nourishes tissues; and carries hormones, vitamins, drugs, and ions like calcium throughout the body. Albumin is made in the liver and its concentration in the blood is sensitive to liver damage. The concentration of albumin in the blood drops when the liver is damaged or with a type of kidney disease called 'nephrotic syndrome if a person experiences severe inflammation in the body, or with shock. The albumin concentration in the blood increases when a person is dehydrated.

How is the sample collected for testing?

A blood sample is taken by a needle from a vein.
