Plasma, the liquid component of blood, can be tested in various ways to assess different aspects of health. One common method, as described in the reference, involves conducting plasma protein tests.
Plasma protein tests are specific blood tests that detect the amount of proteins in the blood. These tests measure different types of proteins present in the plasma, providing insights into nutritional status, liver and kidney function, and other health conditions.
What are Plasma Protein Tests?
These tests are analytical procedures performed on a blood sample. After the blood is collected, the plasma is separated, and laboratory techniques are used to quantify the levels of specific proteins or the total amount of protein.
According to the reference:
- They are blood tests that detect the amount of proteins in the blood.
- They are also known as a total protein test.
Why are These Tests Done?
Testing plasma proteins serves multiple diagnostic purposes. The total protein level and the levels of specific proteins (like albumin and globulins) can indicate various health issues.
As stated in the reference:
- The tests can help your doctor determine your overall health.
For instance, abnormal protein levels might suggest problems with:
- Liver function: The liver produces most plasma proteins.
- Kidney function: Kidneys filter blood, and protein in urine or low levels in blood can indicate kidney disease.
- Nutritional status: Low protein intake or absorption issues can lead to low plasma protein levels.
- Inflammation or infection: Certain proteins increase during inflammatory responses.
- Specific diseases: Conditions like multiple myeloma affect plasma proteins.
Test Procedure Context
Plasma protein tests are frequently ordered as part of a routine check-up.
The reference notes:
- This lab work is usually ordered as part of a comprehensive metabolic panel (CMP) during a physical exam.
A CMP is a group of blood tests that provides a broad picture of your body's chemical balance and metabolism. Including plasma protein tests within a CMP allows doctors to get a general overview of protein levels alongside other key indicators like blood sugar, electrolytes, and kidney and liver function markers.
In summary, while plasma can undergo various tests, plasma protein tests are a key method used to evaluate health by measuring the amount of proteins present in the plasma.
