The micro ESR method is quick 20 min and popular for babies, as the test requires very little blood. It is also useful for diagnosing neonatal sepsis [ 14 , 15 , 16 ]. Automated methods are faster, easy to use, and could be better predictors for autoimmune diseases. Yet, their sensitivity to technical procedures blood mixing, tube sizes, etc. Your doctor may order an ESR test if you have the following symptoms [ 25 ]:.
Factors and disease shown here are commonly associated with abnormal ESR values. Work with your doctor or other health care professional for an accurate diagnosis. The ESR test checks if you have an inflammation [ 3 ]. In inflammation, certain proteins will appear in the blood, such as fibrinogen. These proteins cause red blood cells to cling together and form clumps.
This makes them heavier, so they fall faster, which increases the ESR [ 5 , 26 , 3 ]. Therefore, high ESR shows inflammation.
The higher the ESR level, the higher the inflammation [ 5 , 26 , 3 ]. The ESR test cannot diagnose diseases, but it can track the progress of specific conditions [ 44 ]:.
ESR levels higher than normal may predict cancer or cancer progression, like metastasis [ 59 , 60 , 61 , 62 , 63 ]. Children should have an ESR lower than 10mm [ 3 ]. A low ESR is normal and does not cause any symptoms [ 25 ]. Technical errors during the test such as a tilted tube or dilution error can also give a false high ESR result [ 3 ]. High fibrinogen levels make the red blood cells heavier and increase the ESR. So, genes increasing fibrinogen production could theoretically increase ESR levels.
These include:. Low fibrinogen levels make the red blood cells lighter and decrease the ESR. Inflammation is part of your immune response system. It can be a reaction to an infection or injury.
Inflammation may also be a sign of a chronic disease, an immune disorder , or other medical condition. An ESR test can help determine if you have a condition that causes inflammation. These include arthritis , vasculitis , or inflammatory bowel disease.
An ESR may also be used to monitor an existing condition. Your health care provider may order an ESR if you have symptoms of an inflammatory disorder. These include:. A health care professional will take a blood sample from a vein in your arm, using a small needle.
After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes. There is very little risk to having an ESR.
