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 is sensitive to liver damage. The level of albumin in the blood drops when the liver is damaged, with a type of kidney disease called 'nephrotic syndrome, when a person is malnourished, if a person experiences severe inflammation in the body, or with shock. Albumin increases when a person is dehydrated.
How is the sample collected for testing?
A blood sample is taken by a needle from a vein.
Is any test preparation needed to ensure the quality of the sample?
No test preparation is needed.
