What is ESR Tube

ESR Tube, commonly known as erythrocyte sedimentation rate, specifically refers to the rate at which red blood cells in anticoagulated blood settle in a specific ESR Tube in a certain unit of time. It is a common clinical detection index.

What is ESR 

The principle of the erythrocyte sedimentation test is to place anticoagulant blood into an erythrocyte sedimentation tube and make it stand upright. The red blood cells sink due to their density. Erythrocyte sedimentation rate (ESR).

The rate of erythrocyte sedimentation rate is related to plasma viscosity, especially the aggregation force between erythrocytes. The greater the aggregation force between erythrocytes, the faster the erythrocyte sedimentation rate, and vice versa. To reflect certain diseases of the human body.

The erythrocyte sedimentation rate, often characterized by alterations, plays a crucial role in diagnosing, identifying, and observing clinical diseases— whether an increase or decrease is noted.

Some diseases suffered by the human body

  1. The erythrocyte sedimentation rate can facilitate the observation of changes in pulmonary tuberculosis and rheumatic diseases, as well as the assessment of the curative effect.
  2. Increased ESR indicates recurrent and active disease, and restored ESR indicates improvement or quiescence.
  3. ESR examination can identify myocardial infarction, angina pectoris, gastric cancer, gastric ulcer, pelvic cancer, and uncomplicated ovarian cysts.
  4. For patients with multiple myeloma, there will be a large number of abnormal globulins in the plasma, and the erythrocyte sedimentation rate is very fast.
  5. One of the crucial diagnostic indicators of this disease can be considered the use of ESR examination.

Provide dynamic ESR tubes

We provide dynamic ESR tubes for direct specimens and short 75mm tubes that require specimen transfer.

The dynamic erythrocyte sedimentation tube can be either positioned directly on the shelf for reading or employed with the dynamic erythrocyte sedimentation apparatus during blood collection.

What is an ESR test?

They may advise a blood test called an ESR (erythrocyte sedimentation rate) test. An ESR is a test performed on a blood sample that quantifies and settles at the bottom of a test tube.

The diagnosis of specific conditions is not facilitated by an ESR test. Instead, assistance in identifying the presence of inflammation and the determination of necessary further testing is provided by this test.

The utilization of the ESR test also accomplishes the monitoring of existing inflammatory diseases.

Side effects of ESR test

There are not many side effects of having an ESR test

At the spot where the needle was inserted, individuals may experience a slight sensation of pain or bruising, but most symptoms are alleviated rapidly.

What is the normal range of the ESR Test?

The ESR normal range for men is 0 to 15 mm/hr, while the normal range for women is 0 to 20 mm/hr. This test is nonspecific and only indicates the presence or absence of inflammation in the body. Therefore, doctors usually rely on other laboratory tests, clinical observations, and a person's medical history in conjunction with the ESR test results to make a diagnosis.

What is the ESR test procedure?

  • A healthcare practitioner will draw a small amount of blood from your vein using a small needle
  • The needle is inserted, and they will draw blood.
  • You might feel stung once the needle goes in and out
  • The entire process takes less than 5 minutes.

It is suitable for all kinds of automatic erythrocyte sedimentation apparatus.


What is an ESR tube used for?

The ESR (Erythrocyte Sedimentation Rate) tube is used for measuring the rate at which red blood cells settle in a vertical tube over a specific period. This test helps in detecting inflammation in the body.

What are ESR tubes for?

Erythrocyte Sedimentation Rate testing is specifically designed for by ESR tubes. They play a crucial role in diagnosing and monitoring inflammatory conditions by measuring the sedimentation rate of red blood cells.

What color tube do you use for ESR?

ESR tubes typically come in lavender or purple color. The lavender top indicates the presence of an anticoagulant, ensuring that blood does not clot during the testing process.

What is an ESR Tube normally used for?

Commonly, inflammatory conditions like infections, autoimmune diseases, and certain types of arthritis are identified and monitored using ESR. It serves as a valuable diagnostic tool in the field of medical testing.
