A low ESR is normal and does not cause any symptoms [25].
What causes falsely low ESR?
Falsely decreased ESR results may be caused by low room temperature, delay in test performance greater than 2 hours, clotted blood sample, excess anticoagulant from the underfilled tube, foam from vigorous mixing, and/or abnormally shaped red blood cells, such as sickle cells or spherocytosis.
Is a sed rate of 2 good?
Results from your sed rate test will be reported in the distance in millimeters (mm) that red blood cells have descended in one hour (hr). The normal range is 0 to 22 mm/hr for men and 0 to 29 mm/hr for women. The upper threshold for a normal sed rate value may vary somewhat from one medical practice to another.
What is low sed rate?
Other Tests You May Need The sed rate test can only tell your doctor that you have inflammation somewhere in your body. It can’t show where the inflammation is or what caused it. Your doctor may also test for your erythrocyte sedimentation rate (ESR) or C-reactive protein (CRP) to help make a diagnosis.
What does low ESR indicate?
Sometimes the ESR can be slower than normal. A slow ESR may indicate a blood disorder, such as: Polycythemia. Sickle cell anemia. Leukocytosis, an abnormal increase in white blood cells.
What is a low ESR result?
A low ESR test result may be due to: congestive heart failure (CHF) hypofibrinogenemia, which is too little fibrinogen in the blood. low plasma protein (occurring in relation to liver or kidney disease) leukocytosis, which is a high white blood cell (WBC) count.

Can sed rate be too low?
The normal sedimentation rate (Westergren method) for males is 0-15 millimeters per hour, for females, it is 0-20 millimeters per hour. The sedimentation rate can be slightly elevated in the elderly. Falsely low sedimentation rates can occur in the blood of people with leukemia or polycythemia rubra vera.

What is considered a high ESR rate?
High ESR, value above the normal range. A mild or moderate increase from the normal values of ESR can be considered as an indication of bodily inflammations and the presence of other conditions such as anemia, aging, pregnancy, diabetes, cardiac diseases and some types of infections.
Low ESR is observed in certain conditions where the normal sedimentation rate of blood is suppressed. It is seen in conditions such as: Polycythemia vera where the red blood cell count is extremely higher than its normal value.
What is the normal range of ESR?
What is the normal range of ESR? The normal range for ESR is 0-10mm. With increasing age after 50 years, the ESR rises and, in the elderly, many apparently normal subjects have increased readings. Thus the ESR is of limited value in detecting disease in elderly patients. Physiological increases in the ESR occur in pregnancy and the puerperium.
