rheumatoid arthritis blood test

rheumatoid arthritis blood test

to find out that someone suffering from rheumatoid arthritis blood test needs a physical examination and several other medical tests such as blood tests and scans to help diagnose rheumatoid arthritis blood test, because the symptoms caused by rheumatoid arthritis are similar to some other diseases.


Blood test

Some blood tests can show indications of rheumatoid arthritis blood test, but cannot yet confirm with certainty. Here are some blood tests that can be done:

1.      Sedimentation rate (LED)

This LED blood test is also used to detect inflammation in the patient’s body. When taking samples, blood is placed in a tube in the tube. When the inflammation occurs, the red blood cells in the blood sample taken will fall to the bottom of the tube faster than before.

2.      C-reactive protein (CRP)

This test is done to measure the amount of protein in the blood. This C-reactive protein measures the overall level of growth in the body. By aiming for high CRP levels caused by infections and various long-term illnesses.The right time to undergo a CRP (C-reactive protein) test This test is done to check inflammation in the body. This is not a specific test, in other words this test shows inflammation but cannot show the location of inflammation of rheumatoid arthritis.

3.      Rheumatoid factor and anti-CCP (anti-cyclic citrullinated peptide) antibodies

This test is to examine certain antibodies including anti-cyclic citrullinated peptide antibodies (ACPA), rheumatoid factors (RF), and antinuclear antibodies (ANA), which are present in most RA patients. Some rheumatoid sufferers who are examined for rheumatoid factors and / or anti-CCP antibodies are tested positive, so they are at risk of suffering from severe cases.

So far to detect rheumatoid arthritis is based on symmetrical small and large polyarthritis joints in the lower bones, then supported by the presence of distinctive joints based on rheumatic factors and increasingly high radiography. Rheumatoid factors are often undetectable at the start. And the detection of rheumatoid factors is not specific to RA. This test provides additional information about the diagnosis of patients with rheumatoid arthritis.

Cyclic citrullinated peptide (CCP) antibody tests can be done together with or after a rheumatoid factor (RF) test with this to help diagnose rheumatoid arthritis (RA) to assess its severity. Ten CCP antibodies were also asked to help evaluate the progression of rheumatoid arthritis in people who showed symptoms but did not meet the criteria of the American College of Rheumatology (ACR) for RA.

Anti CCP antibodies are found up to 10 years before the onset of joint symptoms, by developing rheumatoid arthritis it is easier to detect earlier than the rheumatoid factor. From 10% to 15% of RA patients remain seronegative for rheumatoid factor test results. For sampling taken from the blood vessels of the arm.The results of the test When a person has positive rheumatoid signs and symptoms for both CCP and RF antibodies, it is very likely that they have RA and there is a possibility that they can develop a more severe form of this disease.

CCP RF Keterangan
+ both have low levels, and have clinical signs showing RA, so it is likely that they have early RA or that they will develop RA in the future.
+ Clinical signs and symptoms are more important in determining whether they have RA or some other inflammatory conditions.
it is unlikely that they have RA.

However, rheumatoid arthritis to diagnose it can be done without having a positive test for antibodies. This CCP antibody test is quite new, and is currently being used more and more but it is still rare compared to rheumatoid factor tests.Regarding costs, the difference in costs between the rheumatoid factor and the CCP antibody test. The cost of the $ 102 anti-CCP arthritis test and rheumatoid factor is around $ 43 in a reference laboratory at the Cleveland Clinic

4.      Comprehensive blood test This test is done to measure the number of red blood cells that affect anemia.

5.      Antinuclear antibodies (ANA test)

This anti-nuclear antibody test (Antinuclear Antibodies test or ANA) is used for activity patterns and measures the level of antibodies in the blood against the body (autoimmune reaction). The immune system in the human body is used to kill foreigners such as bacteria and viruses. When a person has an abnormality in the body’s immune system which is autoimmune, this immune system attacks normal tissue in the human body. If this happens, the immune system will produce antibodies that attach to the cells of the human body, this will affect the body’s cells to be damaged. This rheumatoid arthritis is an autoimmune disease.

Prevention & warning

What should I know before undergoing antinuclear antibodies (ANA test)?Autoimmune diseases can be diagnosed using only ANA test results. Complete medical history. Other tests and physical examinations were used with ANA to identify autoimmune diseases, such as rheumatoid arthritis Healthy people can also have an increase in ANA in their darrah, as by some people who have a history of autoimmune diseases in their families. The higher the ANA level, the more likely someone is exposed to autoimmune disease. The ANA level can also die with increasing age.

What should I do before undergoing antinuclear antibodies (ANA test)?There are no special preparations, but if certain medications that you take, such as procinamind, pill, thiazide diuretics can affect the accuracy of the test results. Then make sure the doctor knows the medication you are taking.

What is the process of antinuclear antibodies (ANA test)?Following are the steps of the medical personnel in charge of taking blood as follows:

1.      The medical team first wraps an elastic belt around your upper arm to stop the blood flow. This makes the blood vessels under the bond enlarge making it easier to inject needles into the vessels

2.      Then the medical team clears the part to be injected with alcohol

3.      After cleaning the medical team injects a needle into a blood vessel. More than one needle may be needed.

4.      The medical team attaches the tube to a syringe to fill it with blood

5.      Next the medical team releases the ties from your arms when taking blood is enough

6.      Then the medical team takes the gauze or cotton and attaches it to the part that was injected, after the injection is finished

7.      Then the last medical team put pressure on the section and then put on a bandage.


Explanation of Test Results

What do the test results mean?Positive test results if anti-nuclear antibodies are found. But the results of this positive test may not necessarily have an autoimmune disease. A woman who has 65 years of age generally has a positive test result without having an autoimmune disease.
If your doctor suspects you have an autoimmune disease, the doctor will submit a number of other tests. This ANA test is one of the tests used to determine the cause of your symptoms.
