Radioactive iodine uptake (RAIU) is a test of thyroid function. It measures how much radioactive iodine is taken up by the thyroid gland in a given time period. See also:Thyroid scan
|
|
The T3RU test measures the level of proteins that carry thyroid hormone in the blood.
|
|
ESR stands for erythrocyte sedimentation rate. It is a test that indirectly measures how much inflammation is in the body. However, it rarely leads directly to a specific diagnosis.
|
|
The sedimentation rate test, also called the erythrocyte sedimentation rate (ESR) or sed rate test, measures the speed at which the red blood cells (erythrocytes or RBCs) separate from the liquid part of the blood (plasma) and settle to the bottom...
|
|
The erythrocyte sedimentation rate (ESR), or sedimentation rate (sed rate), is a measure of the settling of red blood cells in a tube of blood during one hour. The rate is an indication of inflammation and increases in many diseases.

|
C-reactive protein is produced by the liver. The level of CRP rises when there is inflammation throughout the body. This article discusses the blood test done to measures the amount of CRP in your blood.
|
|
The high sensitivity C-reactive protein (hsCRP) test is a blood assay used to estimate an individual's risk for heart disease and stroke . The test also measures the presence of inflammation or infection.
