What is the meaning of ESR during the examination of human blood(routine blood count).?

Question

The ESR is derived While checking the routine blood count.
what is the meaning of ESR?
What is the acceptable limit of ESR for a man with 65 years

Answer 1

The erythrocyte sedimentation rate (ESR), also called a sedimentation rate, sed rate or Biernacki Reaction, is a non-specific measure of inflammation that is commonly used as a medical screening test.

Men over 50 years old: less than 20 mm/hr(millimeters per hour).

Answer 2

ESR (erythrocyte sedimentation rate) is a nonspecific screening test for various diseases. This 1-hour test measures the distance (in millimeters) that red blood cells settle in unclotted blood toward the bottom of a specially marked test tube. Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and a band or blood pressure cuff is placed around the upper arm to apply pressure and cause the veins below the band to fill with blood. ESR can be used to monitor inflammatory or malignant disease. Although it is a screening test (cannot be used to diagnose a specific disorder), it is useful in detecting and monitoring tuberculosis, tissue necrosis (death), rheumatologic disorders, or an otherwise unsuspected disease in which symptoms are vague or physical findings are minimal.

Answer 5

Why get tested?
To detect and monitor the activity of inflammation as an aid in the diagnosis and activity of the underlying cause

When to get tested?
When your doctor thinks that you might have a condition that causes inflammation and to help diagnose and follow the course of temporal arteritis or polymyalgia rheumatica

Sample required?
A blood sample drawn from a vein in the arm

Doctor’s do not base their decisions solely on ESR results. You can have a normal result and still have a problem.
Moderately elevated ESR occurs with inflammation, but also with anemia, infection, pregnancy, and old age.

A very high ESR usually has an obvious cause, such as a marked increase in globulins that can be due to a severe infection. The doctor will use other follow-up tests, such as cultures, depending on the patient’s symptoms. Persons with multiple myeloma or Waldenstrom’s macroglobulinemia (tumors that make large amounts of immunoglobulins) typically have very high ESRs even if they don't have inflammation. As noted before, polymyalgia rheumatica and temporal arteritis may also have very high ESRs.

A rising ESR can mean an increase in inflammation or a poor response to a therapy; a decreasing ESR can mean a good response.

Although a low ESR is not usually important, it can be seen with polycythemia (a condition where a patient makes too many red blood cells), with extreme leukocytosis (patient has too many white blood cells), and with some protein abnormalities. Some changes in red cell shape (such as sickle cells in sickle cell anemia) also lower the ESR.

ESR and C-reactive protein (CRP) are both markers of inflammation. Generally, ESR does not change as rapidly as does CRP, either at the start of inflammation or as it goes away. CRP is not affected by as many other factors as is ESR, making it a better marker of inflammation. However, because ESR is an easily performed test, many doctors still use ESR as an initial test when they think a patient has inflammation.

If the ESR is elevated, it is typically a result of globulins or fibrinogens. Your doctor may then order a fibrinogen level (a clotting protein that is another marker of inflammation) and a serum protein electrophoresis to determine which of these (or both) is causing the elevated ESR.
Females tend to have higher ESR, and menstruation and pregnancy can cause temporary elevations.

In a pediatric setting, the ESR test is used for the diagnosis and monitoring of children with rheumatoid arthritis or Kawasaki’s Disease.

Drugs such as dextran, methyldopa (Aldomet), oral contraceptives, penicillamine procainamide, theophylline, and vitamin A can increase ESR, while aspirin, cortisone, and quinine may decrease it.

Alternative names ESR

Erythrocyte sedimentation rate; Sed rate; Sedimentation rate
Definition

ESR (erythrocyte sedimentation rate) is a nonspecific screening test for various diseases. This 1-hour test measures the distance (in millimeters) that red blood cells settle in unclotted blood toward the bottom of a specially marked test tube.

How the test is performed

Blood is drawn from a vein, usually from the inside of the elbow or the back of the hand. The puncture site is cleaned with antiseptic, and a band or blood pressure cuff is placed around the upper arm to apply pressure and cause the veins below the band to fill with blood.

A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. During the procedure, the band is removed to restore circulation. Once the blood has been collected, the needle is removed, and the puncture site is covered to stop any bleeding.

In infants or young children:

The area is cleaned with antiseptic and punctured with a sharp needle or a lancet. The blood may be collected in a pipette (small glass tube), on a slide, onto a test strip, or into a small container. A bandage may be applied to the puncture site if there is any continued bleeding.

How to prepare for the test

There are no food or fluid restrictions.

How the test will feel

When the needle is inserted to draw blood, some people feel moderate pain, while others feel only a prick or stinging sensation. Afterward, there may be some throbbing.

Why the test is performed

The erythrocyte sedimentation rate (ESR) can be used to monitor inflammatory or malignant disease. Although it is a screening test (cannot be used to diagnose a specific disorder), it is useful in detecting and monitoring tuberculosis, tissue necrosis (death), rheumatologic disorders, or an otherwise unsuspected disease in which symptoms are vague or physical findings are minimal.

Normal Values

Adults (Westergren method):

Men under 50 years old: less than 15 mm/hr.
Men over 50 years old: less than 20 mm/hr.
Women under 50 years old: less than 20 mm/hr.
Women over 50 years old: less than 30 mm/hr.
Children (Westergren method):

Newborn: 0 to 2 mm/hr.
Neonatal to puberty: 3 to 13 mm/hr.
Note: mm/hr. = millimeters per hour.

What abnormal results mean

Elevated values occur with:

Kidney disease
Pregnancy
Rheumatic fever
Rheumatoid arthritis
Severeanemia
Syphilis
Systemic lupus erythematosus
Thyroid disease
Tuberculosis
Other inflammatory conditions
Markedly elevated values occur with:

Giant cell arteritis
Multiple myeloma
Macroglobulinemia - primary
Hyperfibrinogenemia (elevated fibrinogen levels in the blood)
Necrotizing vasculitis
Polymyalgia rheumatica
Lower-than-normal levels occur with:
Congestive heart failure
Hyperviscosity
Hypofibrinogenemia (decreased fibrinogen levels)
Low plasma protein (due to liver or kidney disease)
Polycythemia
Sickle cell anemia
Additional conditions that may affect test results:

Allergic vasculitis
Atrial myxoma
Autoimmune hepatitis
Endometritis
Eosinophilic fasciitis
Erysipelas
Juvenile rheumatoid arthritis
Legionnaire's disease
Osteomyelitis
Pelvic inflammatory disease (PID)
Pericarditis, post-MI
Retroperitoneal fibrosis
Skin lesion of blastomycosis
Subacute thyroiditis
Systemic sclerosis (scleroderma)
What the risks are

Excessive bleeding
Fainting or feeling lightheaded
Hematoma (blood accumulating under the skin)
Infection (a slight risk any time the skin is broken)
Multiple punctures to locate veins
Special considerations

Veins and arteries vary in size from one patient to another and from one side of the body to the other. Obtaining a blood sample from some people may be more difficult than from others.

The book is amazing in that it not only lowers your blood pressure without the help of medications; it also aids you in having a life that is healthy, happier, and less stressful. This book chanced my life.

Answer 9

Erythrocyte sedimentation rate

A test that measures the rate at which red blood cells settle out in a tube of anticoagulated blood, expressed in millimeters per hour; elevated sedimentation rates indicate the presence of inflammation

Answer 10

Erythrocyte sedimentation rate (ESR) 0 - (Age, +10 if female)/2 mm/hr

ESR (erythrocyte sedimentation rate) or just "sedrate" and CRP (C-reactive protein) are common blood tests often ordered for arthritis. Are ESR and CRP specific to a certain type of arthritis? Are ESR and CRP always necessarily elevated in all inflammatory conditions? What is the significance of the blood tests ESR and CRP?
