Blood tests reveal the presence of inflammation in the body.. know the details


Blood tests may reveal that you have infections in your body. If you have inflammation in part of your body, certain types of extra protein are often released from the site of inflammation and circulate in the bloodstream. About the presence of inflammation in the body, according to the "patient" website.


Blood tests reveal the presence of inflammation in the body


Inflammation and blood proteins

Tests for erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and plasma viscosity (PV) are commonly used to detect excess protein in the blood in this way as markers of inflammation.


ESR (erythrocyte sedimentation rate) blood test

 

A sample of blood is taken and placed in a tube containing a chemical to prevent the blood from clotting The tube is left to stand upright Red blood cells (erythrocytes) gradually fall to the bottom of the tube (as sediment) Clear liquid plasma is left at the top ESR measures the rate at which they separate Red blood cells separate from the plasma and fall to the bottom of the test tube. The rate is measured in millimeters per hour (mm/hr).


If some of the proteins coat the red cells, they will stick together and cause the red cells to fall off more quickly. Therefore, a high ESR indicates that you have some inflammation somewhere in the body.


ESR levels are generally higher in females. The level also increases with age.


CRP (C-reactive protein) blood test

 

The level of C-reactive protein increases in certain diseases that cause inflammation The CRP test measures the level of a specific protein, while the ESR takes into account several proteins.


Plasma viscosity (PV)

 

The conditions monitored by the ESR test can also be monitored by the PV test. It is another marker of inflammation, however, it is more difficult and is not as widely used as the ESR test.


What are the normal values ​​for ESR, CRP, and PV?

 

ESR: The normal range is 0-22 mm/hr for men and 0-29 mm/hr for women.


CRP: Most people who do not have any underlying health problem have a CRP level of less than 3 mg/L and always less than 10 mg/L.


PV: The normal range for an adult is 1.50-1.72 mPA.


Diseases that affect these tests

 

Elevated ESR, CRP, and PV levels are all signs of inflammation.


Rates of ESR, CRP, and PV are elevated in many inflammatory diseases - for example:


Certain infection (mainly bacterial infection).


- cysts.


Rheumatoid arthritis.


Many other muscle and connective tissue disorders - eg, polymyalgia rheumatica, giant cell arteritis or systemic lupus erythematosus.


Tissue injury and burns.


Some types of cancer - eg, myeloma and Hodgkin lymphoma.


Crohn's disease.


Refusal of organ transplantation.


- After operations.


Some conditions lower ESR - eg, heart failure, polycythemia, sickle cell anemia.


It is also lowered in situations where your body is low in protein levels - for example, in certain liver or kidney diseases.
